PCV VALVE REPLACEMENT BMW E90 N46 ENGINE PLUS NON START

Nightmare on the E90 with a non start issue and oil consumption issue.
A few vidoes back we did the crank sensor and the car is is still displaying the same symptoms so as, in an attempt to fix the oil consumption by replacing the PCV value, we took the inlet manifold off, we changed the crank sensor again!
Before taking the inlet manifold off we also changed the camshaft sensors as had a couple lying around and an easy replacement to try.
Going from an occasional misfire to a non start situation though, the problem has grown and I don't know how to fix it!

Thanks for taking the time to help - I’ve actually sorted it now (see next video if you’re interested)!

Check the fuel rail for fuel rail pressure

Thanks - if ECU doesn’t fix it I will do this

I don't think your problem related to hardware Please check following: 1-OBD fuse in the fuse box 2-If rubber seal is bad under the windshield, water somehow finds a way to ecu. Cleaning the ecu socket with brake cleaner or contact spray sorts the problem. 3-Fuel pump may be failed which doesn't throw fault code. 4-You can manually spray gas to throttle valve while cranking to see if ignition is ok. Do you have any weirdness at cabin electronics? Do you have water at passenger side carpet?

Thanks for this. I think you’re on the mark with the ECU - it’s currently off for repair but they’ve opened it up to find water damage so I’m getting a new one!

@@DaveReevesVXR unfortunately e90 has much weaker ecu box than e46. Will you get a ecu, immobiliser and key set ?

@DaveReevesVXR Ай бұрын

They tell me they will be able to program the new ECU and it will plug and play! We shall see…

@@DaveReevesVXRhey Dave - do post an update to hear on progress/resolution- I’m also experiencing crank no start with no tach reading while cranking and have changed crankshaft sensor -thx

I’m working on the solution and next video - hoping to upload in the next few days - should be before Wednesday!

Did the car show any codes when connected to a code reader?

@DaveReevesVXR Ай бұрын

I’ve currently can’t communicate with the engine ECU. I have since used ISTA and can communicate with other computers in the car and various codes re lack of comms with engine ECU… so ECU is currently where my focus lies!

@@DaveReevesVXR I had my ECU throwing wobblies Dave it was simply due to rain water getting into the housing. I too threw money on sensors etc etc. Not sure if this is a E90 thing.

Thanks that’s useful to know! ecutesting.com lists common faults and one where my symptoms are consistent with E90 ECU failure so here’s hoping 🤞🏼

How many miles ?is it smoking badly? if so valve stem seals will definately need changing,did mine last year.

@DaveReevesVXR Ай бұрын

104k miles. It doesn’t smoke badly, I’ve never noticed any myself but it has been commented on when someone was following me a few months back. If the PCV value doesn’t cure the oil consumption then value seals will be my next attack I think.

tnx so much for video... I have same e90 and codes : P1100 and P 1101.. if you can help me.

@DaveReevesVXR Ай бұрын

What’s the code description? A quick Google suggests the codes relate to the MAF but my experience with the E90 has taught me that some codes are manufacture specific so may not be MAF related.

@ghrezakhoshdel8233 Ай бұрын

@@DaveReevesVXR , tnx indeed. I cheched MAF and with new Replaced it.. codes still alive. ( air system gone to sniffing I think )

@DaveReevesVXR Ай бұрын

So you are confident the code relates to MAF? Possible vacuum or intake leak? Issue with PCV valve? O2 sensors?

Hi Dave. I experienced the same issue a week ago. I initially thought it was the ABS sensors or something related but a mechanic confirmed those errors wouldnt prevent the car from starting. Eventually I removed the ECU cover and there was water at bottom of ECU box. Dismantled the ECU and water was inside ECU as well as corrosion on ICS and components. I purchased replacement ECU and car started right up. Water got into the box as the windscreen bottom trim wasn't installed correctly a few weeks ago by Windscreen glass replacement company in Durban and hence water wasn't channeled away from ECU box. Hope this helps. Cheers

Hey - thanks for taking the time to write that. It’s very helpful and you are spot on! I’m hoping to get the next video on this out later tonight…
