[@dazeboy79]

So that's where the coolant is going! Oil filter housing gasket. I'll address this next. I couldn't figure it out. Thank you very much BMW Doctor!! I am changing my valve cover gasket, eccentric shaft sensor/seal and VVT gasket thanks to you.. Update when complete.

Great breakdown of cause and effect of many possible problems, we just got years of ownership experience in a few minutes. Literally will enjoy my car more tomorrow having a better understanding of its systems. Thanks Doc!!!

[@BMWDoctor]

no problem mate thats what I do these videos for

[@mikeb2496]

Doc, so I started my 09 128i about 25°f no codes on the dash upon start up. Went in the house, came back out and had "service engine soon" light. Pulled codes, bank 1& bank 2 lean. I'm thinking immediately bad maf , no way 2 o2s failed at the same time. So there are no drivability issues, basically no symptoms present. I need to get ista from u asap. I heard that a blocked PCV can cause this also. Any thoughts? Have a great weekend!

[@calebcrouch6652]

@@BMWDoctor I'm getting intermittent misfire and ignition codes. I've replaced the plugs and ignition coils. In some of the spark plug wells I do see a little oil and I know that the valtronic motor gasket is leaking as I can see oil pooling beneath it. I don't have Ista, but do have bimmer link/bimmer code. I'm at a loss and don't know what to do next.

​@@BMWDoctorwhere are you based mate?

[@David-gl7rg]

I’ve experienced and fixed just about everything you’ve listed on your video. Coolant hose that’s next to the oil filter went bad last week. The fuel pressure regulator gasket went bad. (Long cranks) replaced regulator and fuel pump. Now transmission need a new oil (6L45) will rebuild it next week with new gasket+filter...thanks to ISTA-D is a MUST for anyone who owns and wants to work on their own car. Oil separator is a common issue in the n52. Check your oil level regularly to find if you’re burning it. Radiator failed and all the ignition coils from Bosch. Currently have Delphi installed.

@@BMWDoctor The catalytic conversion codes due to failing ccv was in the money. I recently had parts of my ccv replaced namely the return pipe after my mechanic told me that's where my oil leak symptoms was coming from. I was going to do the job myself since I've done the valve cover gasket, spark plugs ignition coils, vanos solenoid etc, I'd figured the ccv should be easy for me to replace, especially after watching your video. Unfortunately I had my mechanic do it and they told me one of the tubes to the ccv besides the return pipe I got a replacement for was duct tape together. So apparently they bought some tubing and made their own replacement for it. I got catalytic conversion and catalytic conversion 2 code in my scanner after the job was done, I've never seen these codes before as long as I had my car. I've cleared the codes and they havent come back since I had the job done a month now but I think I'll just buy the whole ccv replacement kit from fcp and do the job over myself after the winter. Wish me luck lol

Your welcome mate

[@mickmaloney1956]

Very nice video. I have two X3's with the N52 engine and have done quite a bit of work over the years. I have an unusual problem that just came up on my 2007. Up until yesterday ran great. Driving on the highway, suddenly the engine started to momentarily cut out the start up. Managed to get off the highway and the idle was smooth and normal. Even at moderate speeds the engine would repeatedly cut out then cut back in. Died once. Almost like it was starving for fuel. Weird hat the idle is rock steady. I actually had an appointment today at a BMW dealer to change the PVC heater under recall. I believe that it is shorted and has blown the #4 fuse under the hood. The only codes that I have are for the O2 sensor heaters that run off this fuse. Thanks.

[@donnymoore03]

Great video. Quick question: Does a 2005 530i E60 M54 engine have the same type of Vanos filter built into the oil filter housing that N52 does?

And there is coolant near there . Is this my problem?? Or just another one ? . It's a 2003 Bmw 530i

Hey Doc Thank you for al information that your willing to help repair our Beemers. I have a 2004 330ci-BMW automatic. When you say don't by after market. I believe you. The problem is that once the throttle body boot went out due to cracks everything else decided to wanted to be replaced. I just got replacing fuel injectors and plugs and coils, and the disa maf again (both aftermarket). Now the car runs really rough and dies after about 12 seconds. Also replaced brake light switch and fuse. Brake lights and trunk light come on and stay after I turn the key.. I truly need some help.

[@rihasanatrofolo2472]

My e90 320d drives flawlessly most of the time, but on some ocassions when I'm pressing the gas to the middle point, it starts to make a slight BRR BRR - BRR BRR BRR- BRR BRR etc sound, until I take the foot of the gas and press again. Sometimes it just goes away, sometimes it stays a while. It's not making the car undriveable, but when that happens it jerks slighty, like it connects and disconnects the gass a little, not fully. Do you have any idea what this might be? My local BMW mechanic was unable to locate the issue, he was also unable to reproduce it, since it happens randomly.

[@ToxicLadyBG]

I had rough idle and cylinder shut downs mid-drive on high rpms on my bmw e90 330xi n52b30A last year. The dealer said that my cylinder head needs replacement due to heavy wear on the camshafts. So i went and bough a new engine instead. Now i have the same issues with the new engine. I replaced the plugs, coils and ccv too. Where should I look next? And did they took advantage on me just to squeeze some cash out?

Question Dr. Dean. I’ve worked my 2008 328xi over. It was running great and now when it gets to temp it feels like my torque converter is not locking and making the car jerk and judder. I have the GM GA6L45R trans which I’m sure is the worst gearbox. I’m wondering if it’s worth changing the fluid and putting a converter additive in or just replacing the torque converter. Any advice is appreciated. Thanks!!

@@BMWDoctor i just read the Wikipedia article to the n52 and they say the same. vanos is for the timing and uses the solennoids, and the valvetronic is variable valve lift wich controlls the amount of air going in and the throttle body schould be in a full open position wenn the engine is running, same as in the n42. yes the n42 is a 4 zylinder but it is the first engine with valvetronic l and the n52 has Valvetronic ll. But it has the same funktion :)

[@alexm2016]

Valvetronic, in addition to throttle body, allows more precise air control. At the same time, engine still can work without valvetronic - in case of valvetronic actuator fails, you can unplug the connector and engine will work only with throttle body.

[@michihoffi69]

@@alexm2016 yep i tried it on my dads winter car (e46 316i with n42b18) and my Observation was when you unplug the sensor it works fine, but when you unplug sensor and motor it is way down on power, wich i guess comes from the valves not opening wide enough:)

[@BMWDoctor]

You just answered your own question exactly that your down on power as the motor is used for the valveteonic system can I ask why you come to this channel with a 4 cylinder engine ??? I’m getting a lot of people with this engine YET it’s a car that won’t ever be on here it’s like your hoping some day it will but it won’t I assure you on that This is a channel like the rest of USA channels straight N52 and 3.0 diesel only

thank you so much dean.very helpful information

[@BMWDoctor]

Glad it was helpful!

[@splne1]

Thank you so much! This videos has been extremely helpful to me dealing with what began as a stall at a red light. 2009 328i N51 I have replaced many of those parts to include, ess, cam and crankshaft sensors, maf, map, injectors and rail, fuel pump, vanos sensors, spark plugs, ignition coils, throttle body, crank case valve. I still have a random start and shut down but afterwards will start and idle fine. All I have left is the fuel purge valve, disa valves, ess motor and leak detection pump. Right now no codes but sometimes it throws the bank 1 and 2 lean codes. What should i replace next??

that's a lot of work put into an n51

Mate whats the intro song on this vid?? cant find it anywhere

[@Hoetobeajew]

Any tips for taking the manifold off without breaking the ccv?

[@BMWDoctor]

There ain’t no way mate if it’s never been off before the hoses will break that’s just how they are so your better off to have a new one ready to go because otherwise you will not be able to put it back on without the hoses

[@MrShaunys1210]

Great vid mate 👌 very knowledgable!! Do you know what would cause the car to kangaroo/buck when planting your foot in an automatic, like it doesnt know what gear to be in if that makes sense? If it helps I could mail you a video of what I'm suffering with 😞 only had it a week and I've changed more or less everything lol

[@BMWDoctor]

Yes mate the vanos solenoids cause that as they control the timing and advance and retard it when you kick down the dme wants to advance the timing but can’t quick enough as your solenoids are failing

My ground strap isn't connected to the ignition coil system..but still starts. ?? My valvetronic motor wasn't working..but the connecter was just loose so it was falling off.

[@BMWDoctor]

Maybe they changed on your engines over there it’s not something I would know about AS we stopped production of N52 here in 2007 it only ran for a year here and we got rid was to problematic

[@raiderED]

@@BMWDoctor it wouldn't cause me any issues tho.?..would you recommend I connect it to the ignition system instead.?and yeah I don't know about that.i just needed my engine swapped and found the n52 to be the best allowed in the US for my car/E60 after a few upgrades. (3StageDisa, Euro Air Box) N53 not legal in US.
