Lots of how to videos on how to remove, rebuild and install all of those cylinders. Anybody with mechanical ability and the willingness to make the effort can do so for a couple hundred bucks. I did all mine only to find a damaged plastic hydraulic line in the trunk that I was able to source on ebay for 30 bucks. Works perfect now. Probably shouldn't own one of these unless you have deep pockets or, like me, enjoy the challenge of fixing it myself. No excuse these days with all the info out there.

True. Now that my auto repair and diagnosis experience has gone way up over the last couple years, sometimes I contemplate getting the next gen SL class with ABC and all of the pentosin soaked fun that comes with. As any Mercedes enthusiast will know, having a second, reliable vehicle is paramount. But then, when you deal with other people's automotive drama for a living, you won't have much appetite left for your own vehicle going "but wait, there's more".

Mine is mint, 51k original miles… One thing wizard didn’t point out is that ‘98 was the last real Mercedes year. 4 cam, 32 valve… the ‘99 that he showed is a very different engine (2 cam, 24 valve), ever since they took over Chrysler, from model year ‘99 and up, the quality is far different. The hydraulics in all r129’s is a huge issue. It’s easy to do manually, or you can spend 4k to do it with a button, but if you keep the car it will leak again in a few years. R129 ‘89-‘98 is one of the best Mercedes 0:04 ever made, the best looking, and with the best engine (m119)

Daimler-Benz took a controlling stake of AMG in 1999. There is in fact AMG models in these model years (1999 - 2003) and even prior: these are the SL 55 AMG, SL 60 AMG, SL70/ 72/ 73 AMG.

I have owned 4 R129 models, 2 sl500s and 2 sl600s, but I still have a 94 sl600. I have replaced all the cylinders along with numerous other repairs,fairly easy cars to work on. Most issues are created by a lack of knowledge of the people working on them. My best and most reliable R129 was my 98 sl500, a near flawless car for the 8 years I had it,but I did replace the top cylinders and the oilers for the cam shafts. If you leave these cars sit and don't use the top,it will develop leaks in the cylinders,it is also a good practice to change the fluid and clean the reservoir when replacing all the cylinders. And as far as relearning the top,it takes about 2 minutes,all the cylinders combined take a morning to do,not to difficult. You can buy all the cylinders in a kit from top hydraulics, or send yours for a rebuild,it was about a thousand dollars last time I checked, and you can also rebuild them yourself which I did do on one of mine. Overall,these are very good cars with a few items you will need to do every ten years or so,but I do agree to replace all the cylinders at the same time.

The 500 is probably more "fun" as far as fast driving goes,and I could see 29 mpg on interstate trips with those,but I sold my last 500 about a year ago after a several year debate between the two as to which one would go. I would convince myself the 500 would go,then I would drive it and couldn't sell it,the decision to sell that one came as I simply needed the space,and a friend really wanted it. I have a small handful(well,two handfuls)of cars and trucks I like,and having two SLs didn't make sense. The older 600 is not a car I would recommend for everyone, I have been in the business for 40 years now and do all my own work,if not for that,I would stick with a 500,or become very good friends with guys like the wizard.

your lucky.. i belong to a mb web site the stories I read made me hard pass those cars.

This is 1 really safe automobile. Built like a tank🎉

I had a shop tell me my caliper was frozen, and quoted me $450 for replacement. I had noticed no symptom consistent, so I said I would do the job. It was the parking brake. So your advice to get a second opinion is spot on. I remember seeing this car - 1999 brand new at a dealer, when I test drove a smaller and cheaper Mercedes. Sweet looking car if you can afford it. Servicing these cylinders looks like a total nightmare.

As the video started, I thought, the customer doesn’t have to drive it with the top down… he can do it manually. Great info Wizard. It is all in the owners manual and several KZread videos cover it too. I bought one of these almost 2 years ago. Been loving it. No top issues so far. But head gaskets was the first big thing to fix. Next is a dash out to repair the AC. Oh, Wizard I found a shop in FL that serviced my non serviceable driveshaft. Where there is a will there is a way!

It makes sense to do all 11 cylinders at the same time. You only want to remove and dismantle the roof mechanism only once. SLs aren't cheap to run unless you're a DIYer. I'll stick with my W204 saloon (sedan).

I replaced the two front hydraulic cylinders in my 99 SL500 when one began to leak a few years ago. Top works fine with no other issues at this point. This car has been very reliable for the past 9 years and 40k miles. Not as much good professional advice out there on these cars as I would like. Especially since I DYI as much as I can. Looking forward to your future coverage on this model. Thanks very much for your video, you do a great job with them!

I was lucky 5 years ago, I purchase a 1996 sl 500 from an old man. He spent almost 10000$ fixing the roof and the faulty biodegradable wiring harness. I bought the car for 5k$ and it's my daily driver. Love it!

My 280sl is fully manuel by me..

I was on a driving tour in Germany in 92 and we had one of these SL's. When you were lowering the top, it was important not to disturb the dance the car makes. Panels open, the windows lower, things whirr - and if you so something like foolishly open a door, the system hangs. At first , we thought we had broken something. Neat car though - incredible turning circle (as tight as a small Toyota!). I preferred the 850i BMW. My favorite Mercedes was the 500E which was so damn stealthy. We had a 190 Evolution but it was hard to see around the rollbar and spoilers. I loved the SL as it looked so cool with the top down. Spending thousands keeping one doesn't seem like such a bad deal - you are driving one of the finest cars ever made and how do you put a price on that? If saving money IS the ultimate goal of owning a car, just buy a damn Toyota.

My God those are great looking cars. Maybe it's because I was a teenager during that period but the late 90s to the very early 2000s overall produced the best looking cars. There was an intersection of curves and straight lines where neither was dominant over the other. I don't think the singular best looking car came from that period, but as far as the number of models goes it's the best.

Holy cow, that second non factory paint job was done by the lowest bidder. Underneath the trunk lid was the first clue. Not sure it makes financial sense on a $6000 car to spend $4500 on a top repair unless its a forever car.

The dead gauge cluster issue reminds me of hondas like mine, where a blown brake light fuse will keep the shifter lock solenoid from disengaging so you can shift out of park.

I had one of these (92) and this is 100% accurate - once one of those cylinders go and you fix it - the rest will soon follow, and there are 11 of them, I am laughing and getting PTSD just watching this!!! got covered in fluid from the cylinder over the driver side seat in the windshield, I only fixed that one and I didn't know about the release levers but wouldn't have mattered.

One guy came up to my dad and told him I will pay $25000 USD if you let it go, but my dad turned down the offer. After 3 months, he sold to his friend for $13000 USD.

This happened to my 2007 SLK55 last month. The hydraulic system cannot take intense heat. If you park outside in the south in the summer a hose will eventually rupture. It is a common issue. I manually put it up and tricked the rear switch in the trunk to believe the trunk was closed (you have to do this for the windows to fully close). It’s now a hard top. I’m not paying 6K to have a 17 year old car fixed just to have a convertible.

“They designed it so that you can manually operate it on purpose” in case the top gets stuck open and it starts raining. All it takes is an 11 mm wrench (not the more common 10mm, that would be too plebeian) and an Allen wrench (both of which you hope the prior owner left in the factory-supplied toolkit), removing the trunk interior panels and the header trim, and contorting yourself to get to all of the manual releases.

It's still less expensive than purchasing almost any new car, but you can't own an old German car and think you can run it like a Honda. And of course, no matter how well you take care of it, it still deteriorates with time, and shows it's age with wear. If all that is ok with you, then buy a Benz.

MB used to be proud that their cars were engineered to be fixable by any sensible mechanic anywhere in the world. I've owned old Mercedes and I was so impressed by that. But now even the 'certified technicians' at your dealer often don't know whether their butts are bored , punched of countersunk. They assure you that your car is 'fixed' and the truth is obvious before you are a block down the road. What MB dealers are really good at is reaching into your pockets and smiling sweetly.

For that kind of repair cost, I'd just put the roof up and leave it there. But then again, I'd avoid convertables in general because I've heard of far too many issues with their roofs. Same thing with sunroofs - I've seen too many people get a free shower when those things inevitably start leaking.

The answer to these convertible top problems is to ditch the Mercedes and buy a Lexus SC430. The convertible hard top on my wife's 2004 still works perfectly (as does everything else on the car). They're both boulevard cruisers anyway. There's no one driving the Mercedes like the sports car it pretends to be.

A mate picked up a SsangYong Musso (not sure if they were ever sold in the US, but the whole model range takes the prize as the ugliest car maker of all time)... They used a fair bit of Mercedes tech and are made in Korea. Back to the mates car. He got it really cheap, because the four wheel drive system was not working. The owner was told the transfer case was faulty and it would be worth more than the car was worth to repair or replace it. So, the mate just drove it around like a regular car, he did not care about the 4x4 system... One day, he was talking to an auto sparky mate... and mentioned the problem with the Musso. The auto electrician suggested he check the four wheel drive light in the dash.. He removed the instrument cluster, replaced a blown bulb and the car had 4x4 again (the transfer was shifted electrically).. This was something he could laugh about... but it might not be so funny if you are half way along the Canning Stock route (1100 miles / 1900 km of 4wd only track in Western Australia with no residents along the way) when the light bulb blows.

I remember seeing a video a long time ago where someone was taking those locking cylinders out on the windscreen because at the attachment point on the cylinder, the line would break off. The rebuilder redesigned that so the line couldn't break off again. I couldn't see these well enough to see if these were that way, or maybe mercedes redesigned them to eliminate that problem.

M113 V8 engine. I've also heard that this in its relatively simple design is a durable and strong engine. Its only downside is that it doesn't seem to be possible to rebore the cylinders if there is scoring and wear on the cylinder walls. I am glad the Wizard showed how it is possible to maneuver the top manually. Me,, being on a budget I would just design some cables with levers so I could take up and down the top manually without having to access the "locks" from the trunk or have to use an Allen key. But Shure! I'm on a budget. If not? Rebuild all the cylinders etc. But what about next time some little sensor brakes and the system stops working again.🤔😬

A bluetooth OBDII dongle and an app like Torque (Android) will display your speed, rpms, fuel, etc even if your gauge cluster goes out as long as the data is on the canbus. It'll also let you read your error codes so you have an idea what's wrong before you go to a shop so you're not shocked by a price or know when you're possibly being scammed. Had a 2008 Nissan Versa and more than once the bluetooth OBDII reader was a huge boon. Not an expensive one, just a little $12 deal. Left it in place as a permeant part of the car.

I don't know about the tops, but I know the suspension hydraulics can fail because MB insists on using fittings that deteriorate over time and little bits of plastic get in to the pumps and cylinders. So thousands upon thousands of dollars because they save a dollar or two on the original fittings.

Love your videos Wiard! Very relaxing, enterntaining and informative all at the same time. Please do not change how you do videos!

I got to drive one of those, pretty fun car, i remember it wanting to spin the tires on the 1-2 shift

I had a 2005 Porsche Carrera S cabriolet. The top worked improperly, so I took it to my local Porsche dealer. (My mechanic told me to NEVER bring that car to him for any reason.) Porsche wanted $2000 to replace a potentiometer, located behind the driver's side rear interior panel, just to be able to "further diagnose the problem". Looking at a potential huge repair bill, I said no thanks. Other necessary repairs would have put me in the poorhouse. After spending $14,000 on various repairs in a year, I was ready to sell the car. Fortunately for me I broke even by selling the car.

You can buy a computer safe logic probe for about ten bucks at harbor freight. Let's you safely check fuses like a pro. Occasionally, a visual inspection can miss a bad fuse and it takes longer to pull each one out and put it back in.

On an NA Miata with automatic transmission, the horn fuse share it's power with the rear brake lights and the brake/shift interlock, fun times

Thanks, I may be getting a CLK 500 with top issues. it is up now and that's what I prefer. BUT it's good to know the expense involved. It runs well and is German built. Fun to drive

Lots of cars are like that I have found in my years working on cars they don’t always tell you were the power comes from .

The next weakest point will always tell you you should go for a full rebuild . That work in everything that shortcuts are made👍👍👍

A million years ago when I worked on those, we had a guy at a hydraulic shop rebuild all the pistons. It was far better, used aircraft grade hydraulic fluid which was the best stuff out there.

so glad i sold my 1999 sl 500 sport 6 years ago for 15k . It had 45k miles on it and the roof was perfect nothing was changed

What do you think of producing a "manual latch kit" that attaches to the hidden releases for those of us who dont mind raising and lowering the top manually. The kit would make the hidden latches completely accessible and easily manipulated. (Maybe even go so far as to remove all hydraulics)

Always fancied an R129 but the roof and the bio-degradable engine loom have always scared me away. I'll admire from a distance thanks.

The inter-related electronics and hydraulics on late 90s-early 2000s Mercedes was ahead of its time, and absolutely sucks for repairs. Our CLK top will not go down and will cost more than the car is worth to fix. Too bad, because the car is almost immune to rust and the engine runs like a champ.

Funny and irritating things and from a design point of view about German cars: 80% state of the art engineering and design - the other 20% so OBVIOUSLY poorly conceived with unsuitable materials and fragile cross-sections that can hardly make it out of warranty. Almost like the entire product is is split between 'Klaus' and 'Fong Kong where the result is: mostly working but an infinite list of complete irritation.

@@godfreyberry1599 Overly complex and it's necessary to take too many things apart to get to the part that needs to be replaced or repaired. Scanning for codes results in a huge laundry list of faults even when the car seems to be operating just fine. But the car is as solid as a tank and runs like a top 99% of the time.

For many years American cars were wired with the tail lights in series with the instrument panel lights. I'm surprised you didn't know this. Years ago if your instrument panel lights went out you knew you had no tail lights!

Not really a mercedes guy, but I like the styling they had between the 80s, 90s, and beginning of the 2000s, a lot more than the 2010s and 2020s.

Really hope to own that particular year of sl500, even if it had a bad top. As long as it still has its hard top and everything else is in really good shape, that’s something I could have fixed later on but I can still enjoy the car.

I have one and I love it. Mine came with hardtop. Surprisingly the drivetrain hasn’t given me any problems and it’s a 1992.

I'd like to add that at 5:00 you could say that even taking this car to an HONEST non-dealer mechanic could cost a bunch of time to find such an idiotic electrical problem... My Buick has two IP fuses (instrument panel) and the rear lights are totally separate.

There were AMG versions sold through official MB dealers. SL 55 AMG, SL 60 AMG, SL 70 AMG, SL 72 AMG and SL 73 AMG! If you can afford one of those you can afford roof repairs. Many owners with the normal cooking versions just use the removable hardtop.

they said this is the zenith of Mercedes but 1. the biodegradable wiring harness 2. unfinished workmanship (e.g. unfinished paint of the trunk lid)

Also, back in 1992 I believe, when the SL first moved to BEFORE the numbers, I went car shopping with a friend for either an SL300, SL500 or a Cadillac Allante. If the Cadillac salesmen hadn't damaged the very simple top mechanism for the Allante (which also gave 2X the trunk space as the Benz) I think he would have bought the Cadillac. I could not believe that the SL had SEVENTEEN hydraulic cylinders involved in the top and the rollover bar!! And after all that, it had a plastic rear window... I think the old Thunderbird and Lincoln four-door convertibles were actually simpler. By comparison, my 55-year-old Wildcat now needs 1 top-cylinder rebuilt or replaced... and it text about 15 minutes to remove the rear seat and the side panel to get at it.

Hi Wizard, I have a '94, hardtop on 90 percent of the time. Took it off and soft top worked fine but after a couple of uses, small leak driver main cylinder- a few drops on the floor after using, nothing continuous. The way I see it, in summer I keep top down, can always manually raise if a surprise storm (check the forecast).The rest of the year, hardtop is on. So I don't have to rebuild the hydraulics until I want to. In fact, unless the one cylinder starts badly leaking, it is the "weak link", actually de-stressing the others, and I will monitor the hydraulic fluid level in the trunk. Worst case, a rebuild for $5k is well spent, unlike those BMW's, this engine is bulletproof, the body is great,it is a fantastic value.So if you buy a good one for $6-8k and add the $5K, you are still under 20K for a great roadster like they don't build anymore, even MB doesn't. This was the pinnacle, the 90's and Bruno Saco.

Hello reality check a white one cherry 80k gorgeous would not sell for 4k in san jose ca a very wealthy area. Over 1 year. not a ding clean engine. I hard passed knowing they are money pits. He finally did a trade to get rid of car. THATS REALITY.. and they need more then 5k to fully maintain the car. A lot has to be redone at that age. i redid my 280sl I know the costs and aresa that fail. driveline, top, list goes on.

@@peter-pg5yc Good points but maybe he has a Prius now and is happy. Agree if you can't afford the expense get a reliable daily driver. The "reality" is that it will be a very sensible daily driver, a Prius or Subaru, won't cost much, and may be the only car you will ever need.

Yup I always get hardtops. My current car I special ordered without a sunroof as well.

Very wise move. Sometimes extra complexity is worthwhile, but IMO sunroofs and convertibles are just asking for trouble. If you really MUST get something like that, a T-Top is arguably the best option, but a simple hard top is so much less trouble in the long run.

What a great instruction. Everyone who has an SL should keep an Allen Tool set and a couple of spanners in the car to be ready for the roof fail. Thanks for doing this video!

They actually come with a tool for this. It is a 10mm (not 11mm) thin wrench on one end and the 6mm hex on the other end.

I have a 1990 Corvette Convertible, the top is manual, it's engineered to open and fully store in seconds. Why would Mercedes over engineer and inevitably complicate required costly service in the future. I believe that would create buyers remorse and affect future sales of Mercedes

The engines work great in old cadillacs ,not as reliable as cadillac engines but it does go faster.

When I changed the cylinders in my 2001, I used the service from Top Hydraulics where they sent me a set (big deposit), and refunded my deposit when I returned my 'cores'. Allows a single mechanic's session...

I'm so thankful to own a Miata. I reach back with one hand and open or close the top is seconds manually.

It'd be interesting to see a comparison between this type of convertible top system to that of a Lexus and Miata PRHT systems. I'm sure the latter two do not include hydraulics. My Miata with PRHT is now 16 years old and still works perfectly.

Their a lot of shops witch refuse to repair Soft Tops. God bless the Wizard.

You are quite the professional in your craft, and a fine speaker.😊

Looks like tubes from ABS braking systems on that top system. Classically over-engineered Mercedes. Love it.

ill just ride and manually put the top down and up that sounds good to me just got to make sure the AC is working 😊

Bottom line is I would stay away from the R129 unless it was a dream car for you as a kid, like it was for me. This top is a major concern for a car that is still not very valuable, it would be different if it was a $40-$50k car but a $4K top rebuild for a car worth $7-$8 grand? Doesn't make much sense. Too bad they just didn't make a manual top like the 107 had.

My first ever girlfriends mum had an sl320, used to cram in it to go home from school, I remember thinking being able to stick my finger out of the back of the convertible top being pretty poor. My mum had an Audi cabriolet at the time and you couldn't do that, the top was much tighter and felt like a hard top car. Ahhh memories.

Love these SLs!

That's a golden information for convertable top owners.

Stupid design for a top. Cables and a couple electric motors were fine for DECADES.

Reminds of why I liked my C5 convertible, well engineered manual top. I get the luxury aspect of a motorized top...but I'd much rather have a manual, simple, mechanical top. That's more or less never going to happen again though I'm sure

Respect to Wizard! 6:03

Those are like 25-35k here at north europe. Pretty valuable sports car

Jesus the Wizard is doing his best to drive down the prices on these cars. I spent 8 grand on mine, over 3 years and 21k miles I have put 4K total in the car. It is a dream to drive.
