Thanks for your help Dean. I have an E46 with 26X,XXXmi I've had for 6 years and put 140,000 miles on, just purchased and X5 with a N52 and 167,XXX miles. I'm going through it. and needed a list of things to check. Between you and Nathan, I feel confident I can get this beast back to snuff. Just did the OFHG and OFcooling gasket. Vanos Solenoids, Thrust arms and end links scheduled to arrive today. Had to do the wiper fluid pump last week. Disa and CCV is next.

With absolutely zero car knowledge your channel has saved my car. It was in brutal condition when I bought it, and now it runs like a gem. Appreciate it brotha

Good luck with the winter, doing the same in the north east states, lil snow is a blast a lot is a pain

Learning so much from your videos!! Can’t wait to start building my N52, currently have a 07 E90 328i sedan and I love it so I can’t wait to squeeze some power into the car

I liked and subscribed keep on bringing n52 stuff plzzz

Thank's . My issue was idle drop at start and a error on exhaust solenoid,after i clean the exhaust vanos solenoid i solve that.Keep up the good work!

Thanks for the very informative video. Just wanted to ask how do you update the engine software since I just replaced my vanos solenoid?

Thanks for the video - useful information. I have changed everything you have identified except the disser valve. However I waited until I got codes or other faults. I only replaced one coil not the hole set. A new coil on one cylinder does not put extra load on old coils as they are completely independent of each other. The only additional item I had to replace was the starter motor. Sold the car with 320,000 kms. The new owner has the full history of the items replaced. PS - changing the water pump and thermostat requires the coolant to be replaced and should be the only time anyone needs to touch the coolant.

I bought a 200k mile 325i manual and videos like this have kept it a happy machine. I lost the water pump once in a dramatic explosion of steam. Fixed it for 150$ amazon replacement and a 10$ metal hose flange to replace the original chocolate hose flange. Lets go another 5-50k miles :)

Just picked up a 03 325i coupe on 122k. Going to work my way through this things over the next few months bit by bit. Thanks!

Man, you're so correct!!! I had all of those changed except the belt tensioner

It's not that hard to do all these things. Really good info. The secret of motoring is to concentrate on the weaknesses of whatever you drive. This has been true since the beginning of the car.

Thanks for the part on the valve cover bolts. My records show the valve cover gasket was done ~20k miles ago, but I just found a leak and a couple of the bolts could be turned by hand!? I had just changed the CCV system and it was crap. So either they torqued em wrong on install, or they were loosened from the increased pressure like you said. Once again you clear up a strange situation.

I disagree about the temperature gauge. They could easily include one set to the appropriate temperature range of the engine. Ie hot for hotter than normal. A gauge gives you warning of a temp increase before it's critical

BMW Doctor O2 sensors agree that basically never fails but some have noticed big improvements in fuel consumptions as they get aged.

Just bought a 09 328i from a Police Impound Acution and it has 188K miles, so this helps on what I need to get changed, just the other day replaced the starter, crank sensor, oil housing gasket, intake manifold gaskets, oil pressure sensor, crankcase vent...the intake has a lot of oil inside of it as well.... and will be replacing all the vanos BS and installing a Aluminium valve cover and of course the belts and transmission service.

Just picked up a 2008 125i cabriolet manual with the N52 with 104,000 miles and it’s got an oil leak dripping oil near exhaust manifold, I’m going to order the replacement and new bolts this weekend. Paid £3400 for her and don’t mind paying to bring the engine and components as close to new as possible. I’ve had DSG golfs and stuff in the past and I really have a soft spot for the configuration of this little car N/A 6 cylinder, 6 speed manual, RWD, Coupe. this is now unheard of!

Excellent information. I got 220,000 miles on my 08 528i and have already gone through the valve cover gasket, spark plugs. Football gasket, eccentric sensor, oil filter case gasket, expansion tank, battery and vanos solenoids. Im getting ready to order new vanos solenoids again 4 years later. The waterpump still has a strong jet of coolant at the expansion tank. Are the motor mounts a bad failing point for these cars? My 528i makes a sound right at the start only and dont know how to trouble shoot it. I know my sister is having her motor mounts on her 07 328i replaced due to a rear end collission. As soon as she got hit, her cars started vibrating like crazy. Just like I thought, it was the motor mounts. Keep up the good work and thanks in advance.

I've done the OFHG so many times at this point, there's really no issue doing it as needed whenever they do start leaking.

And if you do where are you base? Would like to bring my one to you for it btw great videos!

They could have put a temperature gauge on the cars. All they had to do was to design the gauge to read normal unless the temperature is out of tolerate according to water pump operation thermostat operation and the coolant temperature itself. All my cars the temperature gauge sits exactly in one spot no matter what. However outside of that parameter it will show a higher reading. You are right I was thinking since the electrical water pump and thermostat came on BMW's they took the coolant gauge off at the same time. So it makes sense.

I bought a 08 BMW z4 3.0si with 127k on it. It seems everything has been replaced from just looking as for what I can tell. The Valvetronic gasket is the only slight leak it has but I am replacing that this week. I think the Disas have been replaced but not 100% the top caps are green in color if that makes a difference.

Great video! I have the problem that my N52 engine has a rough idle only on cold start. Already changed the spark plugs, solenoids, chain strengthener and the twi DISAs on the engine. What else could I replace?

Hi dean. I am a international student and studying in Canada. I bought a 2011 328xi three years ago. Now it just hit 100k km. I am planing to change those parts that you mentioned in this video. But I am having a hard time to understand your speech. So can you make a list that could help me to find all the parts easier? and how I can do the engine module update? 0:45 for the engine oil filter components, do you mean need to replace the whole engine oil filter housing parts, not only the cap. is that right? 4:05 do you mean the CCV intake manifold needed to be replaced? 5:00 do you mean the valve cover gasket set need to be replaced? and for these bolts what size i need to get?

I have a question about the solenoids I have some issues whit my n52 we did diagnostic and found that 1 of the solenoids is not working the car is lacking power and is slow on the trotile when. i press it hasetate to speed up. I am waiting for the new solenoid but I wonder is it possible the rataling noise to be from that as well. because it didn't show nothing else on the computer? will be. super thankful for any advice sorry for. my bad english :)

@@BMWDoctor Please allowed me to put you a question; I own an 2006 E90 325i with N52 engine and about 120.000km; I have it since 3 years ago. The engine runs smooth, no major issues while running. Excepting a little bit higher oil consumption, about 1l at 2000km. But the main issue would be the idle when the engine is cold(more than 8 hours). And this happens only when it's warm outside in the hot seasons; no issue in the cold season. After starting the engine, for about 5 to 10 seconds, the idle could be a little bit unstable but after that time, everything is ok. But sometimes, the idle just drops bellow suddenly and the engine just stops. After I start it again, no more issues, the idle is stable. Please advice what could be the problem. The ignition coils and spark plugs have been changed two years ago at a BMW dealer. At low rpms, I do not feel lack of power( caused by potential vanos solenoids issue).I never had the check engine shown in the dashboard.

The best upgrade on my 2011 X3 with 100k somewhat problem free miles was trading it for a Lexus.... these 9 problems, and several other more was the final straw on a long list of things that cost way more than the car was worth to fix. I also have a 2013 328i F30, with 143k miles on the 4 banger...zero problems, but its not worth two dollars so I just tool around with it until the engine has a catastrophic failure....

However I do love the F10 five series as well and a 528 I would probably be a reliable right, Of course with a thorough inspection and proper maintenance history

You have said to update the engine (what do you mean by that)? And if i have the n52 without vanos solenoids can i put them and how to make them work with the ecu

Hello DR. I have a 09 528i and the ccv diaphragm keeps breaking I replaced it with the quick fix from Amazon because I did not want to change the intire valve cover , unfortunately it only last a week. Does the vanos cause that?

This is all spot on. My 180K N52 (328i) has all of these except the vanos done. Most items got replaced at ~80K. But did my coils and second set of plugs about 170K. The valve cover had to be replaced because the CCV is built into it, at 175K. What a stupid design that is. At the current time I periodically get an oil burning smell, but no drips are visible on the car or the garage floor. Any ideas?

Dr. BMW! I have a question I recently purchased a 2006 Z4 with N52 engine and only has 6k miles on it, kept good and checked engine bay very clean no oil leaks. I've done the oil change and windshield sprayer waterpump. Is any of the 9 points I will need be alarted soon?

you spoke about upgrading the modules. What model would you recommend and what performance increases would I gain?

Just bought a 2007 530i with 240k but it runs great. It was maintained really well the car drives and looks loke almost new. What should I keep an eye on at 240k

Did the N52k suffer water pump problems or did they upgrade with the K variant ? 2009 e60 LCI

I have ruff idal for a couple of seconds only when engine is cold and it's frowing up vanos inlet exhaust codes ?. Thinking it's vanos solinoids so changing then but how do I update the engine as explained on video ?

i have a friend that has the same engine and never had any issues with the engine other than oil leaks. and now is 177.000 miles and still gOing

I got i oil leak come from the left side of the engine by those bolts you mentioned so does that mean I need a new head gasket? Also I have a code that pops up saying my car is not getting a good fuel to oxygen ratio ( bank 1 and bank 2, are rich) what would that be?

Engine runs GREAT ! I had Mom appointment for her to look at a Subaru... They had sent it out for detailing and pulled the gold onto the screen. Mom said , " I want it, I'm tired of looking. For $11,000, Mom got the E60 N52 528i 2009 (or 08 * lol * ) - 88k miles - in May '22. I asked sales rep to pop hood after test ride (10 miles maybe) ( with a weird disturbance mid run). Residue all over, but not thick black... Just moistened , so I asked what was leaking... "Oh nothing, probably last guy to oil change spilled a little..." After home a month, total brake and rotors, then top front coolant hose connector (one of many things readily emitting residues). So then oil cooler filter housing gasket change and pulleys belt and tensioner, valve cover gasket.... But a vibrating was irritating to Mom ... I re-lubed/replaced caliper pins, no fix... Then recalled for pcv valve tube change... They told me needed rotors ... The ATE's I got for it weren't quality enough .... BMW's rotors next great, but pinhole steering fluid leak low pressure and old intake clamp inches from steering pump pulley made belt jump and shredded everywhere... ugh....a piece melting belt clabbered on the water pump bolts and melted up the rubber washers.... NEXT....

Where do you go to "update" the ecu?

Hi I have a BMW 325i with the n52 engine I'm getting a 2d0f air mass metre code. when you start the car on a cold start and you press on the brake pedal the RPMs go up and down between 600 to 1000 once the car is warmed up pressing the brake does not effect the rpm also the car doesn't want to start in temperature bellow -5 Wich I assume is because of the the code

Great, informative video, pity about the dumb music lol!

Mine was ticking when I first got it, but after some quality oil it went away on its own.

Around 100k is when you need to replace the expansion tank, those almost have the exact life span of 100k. It is hell trying to get it seated right, and if yours goes, it sprays everywhere and possible shorts the fan, and a few electric components.
