Smart Fortwo 450 Starter Motor change. First, remove everything...
Автокөліктер мен көлік құралдары
What a stupid place to put the starter motor! We opt to drop the entire rear subframe to gain access, but it still isn't easy! The Smart 450 or Fortwo is a bit of a pain to work on.
Huge thanks to Matt and Craig for their help, Evilution for useful information and you for watching.

Next time you drop the subframe it’ll be under two hours,welcome to Smart ownership, you’ve reached the first qualifying criteria. That looks to be remapped to me from the look of speed accrual/ sound of the engine. Safe mode is triggered through overboost, it could be down to exhaust manifold leaks (which you may be able to see underneath) or someone has ‘wound tight’ the wastegate arm for more boost beyond what has been mapped for. All of these items are accessible from underneath/ at the back. Best of luck from a fellow (very experienced) Smart owner!
User manual department: Everything is way too difficult. People will just think this is a really stupid car. Marketing department: Well in that case we'll call it a Smart. That'll fool 'em.
The part you circled is the fuel pressure regulator and the hose goes to the intake on the other nipple where you repaired the breather hose. Also the one-way valve on the breather is often faulty as well so check it, too. And you really should've done the spark plugs when you had the engine down, much easier that way!

Great to see the Smart motoring on up the road, she looks very gutsy. That looked like a whole bunch of work, very well done to the guys who helped too. Amazing how much can be achieved when the weather is with us. Fascinating how they package all the engine and running gear into such compact cars. Been very tempted to buy one myself to teach my son to drive.
Nice work Ian 👍
Well done to friends that give you a hand! Plus MiniHubnut’s camo game is strong!
Great video. Really enjoyed the progress on this one. Good to have supportive pals. I do like your Smart.
That was a job and a half, crikey! Well done Ian and friends.👍 Fingers crossed you're able to get the running issue sorted.
A Superb result!
Brilliant job on the Smart, top stuff, best wishes.
Well done
A top job Hubnutters and helpers. She lives again to enjoy time out on the open road. I guess this is one of those jobs that if you know how to do it from the outset takes a lot less time. The amount of jobs that I've tried in the distant past that required taking all sorts of stuff off just to learn how to get to other stuff took ages then finding out that I needn't have bothered doing half the stuff. Anyway, let's hope that the limp mode issue is diagnosed and hopefully an easy and cheap fix.

I had one got rid after 6 months, horrible things everything is hard work.
I’ve had two smart 450 and I loved them both, especially the cabriolet. Top tip is to change gear yourself and ignore auto unless you are in city traffic and get used it before you judge it. The clutch servo is quite easy to take off and service and you can dramatically improve the gear change speed. The electrics will play up due to the horrible lead free solder that results in dry joints. Well done for getting that started done, I bet that now you have done one you could do another In a third of the time. These cars were just not designed to be serviced by home mechanics, but it’s all doable.

Well done Ian. Limp mode could be down to over boost protection or a boost leak around that iffy rubber coupler on the throttle body to boost pipe joint. Either of those or a slightly duff MAP sensor. Hope you get to the bottom of it

Good to see it now starts, I rebuilt the engine on mine, the first rebuild i have ever done but it was straightforward. Once the engine/subframe is lowered its not much more work to take it out completely and its then much easier to work on.
Excellent, Ian , enjoyed that. Pleased, it's on the road 👌, You could try disconnecting the battery for 10 min and reconnect , it can sometimes reset things ... check the Turbo /manifold, make sure it is nice and tight, and also make sure there are no leaks in the vacuum pipes ... it may have also had a remape ?that can cause issues sometimes 🤔

Well done on a difficult task.
What a result, well done you lot! "Bloody Cowling", wasn't he the boss in The Professionals?

My mate had one of these brand new back in 2004, and he said you either take it to a dealer, or drop the rear subframe. I think he ended up doing most of the stuff him self on his, due to the cost and time, when it ran out of warranty. His ended up been scrapped off, due to the mileage and what it needed doing. He had done 70k and the engine was an oil burner by then. He said it was getting very expensive to fix, and that was him doing it. The car didn't see 10 years old at all, might have been lucky to have seen 6 years. A work mate had a newer model and that had some trouble, and no garage was keen on going anywhere near it at all, Due to the faff on. He was either getting quoted on what the car was worth at the time, or they said we cannot touch it.

I'm so glad you got some kind of win out of that. I had a random flashback to my last year at school, and a friend who had a pre-war Morris 8, which he worked on in his garage. There is no question that modern cars are better: but I do wonder if all the complexity is necessary for that improvement. 13:50 If only everybody switched to sustainable fuels, smelly cars would be less of a problem. I was driving on the motorway and started getting hungry. I wondered why, and then saw that the van in front proclaimed its use of bio-diesel. No wonder I was suddenly fantasizing a nice serve of chips.
Smart Because Hubnut
Having owned several Smarts, I feel your pain but stick with it, they really are fun and economical little characters.
Imagine if you couldn't do it yourself -the labour charges in a garage would be more than the car is worth! Thinking of the days when I could swap the starter motor of my MK1 Cortina in 20 minutes flat!
Well done, Ian. You may find an intermittent problem with either the throttle position sensor or the mass air flow sensor. Keep in mind that the electrics of that era are multiplexed, which is Bosch taking up the burned out torch from Lucas Electrics. Lucas invented darkness. Robert Bosch refined and perfected it. Wait until you have to change an indicator bulb! Even better, the front wing comes off to change a headlamp bulb.

I see you have the milk container lid washer bottle update too. 😂
When you turn the ignition key to the "start" position on a Smart you're doing no more than telling the computer that you'd like the car to be running. To begin with it feels like a conventional car, where that extra bit of twist controls the starter motor but on the Smart it doesn't. You can turn the key then release it and the starter motor might not activate for another five seconds or so after you've released it.
this explains why, when these start having some trouble, they can become breakers. Due to the time and hassle, from what i have read in the past. i would hate to think how much that would have cost in labour at a garage, just to change a 3 bolt starter motor out, that would have been normally 2 hour job if that on some cars.
Halfway thru I thought, oh god, tell me he’s tested the used starter - it worked, so well done but what a job. I recently bought a older Skoda fabia for my son and to check the power steering you have to take the battery out, which you can only do after removing the air box so of course no one’s ever done it and the top won’t unscrew without breaking it #grumble.
Awful to work on but, a great result. Happy days.

Nice job. Im sure once you’ve done this the first time, subsequent times become trivial.
Interesting Job Ian, well done for having the patience to see it through. Sounds like you might have a degrading coil pack on one plug maybe? can you put a tester on them to check if they degrade as they warm up? or does have a traditional coil? if it does maybe clean the connections and replace the lead for a new one.

Imagine my surprise when yours just started up without the brake depressed. And yes, mine sounds like trying to start a car that's had timing too far advanced as well. Disconcerting at first but I am used to it now.

Well done getting 'one job' done on the car that gives back like a smart Alec ... Do you have a diversion planned when on route back from the auto-jumble? From the experience of having paid for storage for 'stuff too good to throw that has been taken to several car boot sales and still not sold', I can recommend cutting your losses ... virtually nothing that didn't sell the first time was sold after that. I'd suggest only keeping items small enough to post and offering the hublets all profits on ebay sales ... though perhaps for rare parts, once you have catalogued them, you've got a large enough reach in the car community to find a good home for the real rarities. Good luck!

Sounds like a vacuum issue. Since I had the problem on both my old 9-5 and VW T4, all the little vacuum pipes are the first things I change on any « new » turbo car I buy…
Variable boost: My 2016 LPG converted Fiat Doblo T-Jet used to have (and once in a blue moon stil has) the same issue: normally near 1 bar of boost but sometimes only wastegate pressure of about .2-.3 bar, mostly in spring and autumn, no fault codes, clearing up after a few drives. First thing to check (wasn't the issue with mine): the electronic bleed valve that regulated the boost pressure Second thing (this was the issue with mine): I noticed I had this issue when I sat in traffic shortly after cold starting, causing the automatic petrol-to-LPG switch to happen while idling, making the air-fuel mixture temporarily too rich for just long enough to trigger some sort of limp mode, but not bad/long enough to trigger a fault code. Some adjustments in the LPG settings solved this for me (mostly). Residual old fuel (especially if there's ethanol in it) or the injectors not entirely performing to spec could cause the same issue.
Obviously they were designed to never ever break down! ;-)
