you need to wiggle them in a circular motion when pulling them out. I took mine out in around 10 mins, the screws are the worst bit!

By the way DO NOT take out the VANOS solenoids! (unless you absolutely have to!), it took me 6 hours to get them back in! it was a complete nightmare! for some reason BMW decided to design in a ridiculous o-ring compression tolerance in the timing cover holes, you have to lever them back in with a special tool! definitely not a job for the faint hearted!

No your fine, the VANOS solenoids are right at the front of the engine, two on each side. I will post a pic of what they look like.

Edit:

This is what they look like.



The green o-rings seem far to big, they may have swollen in the cleaning fluid I used, I'm not sure exactly.

That's definitely the camshaft sensor you have pulled out!

They were 100 times easier to put back in! A tip: smear a little engine oil on the green o-ring to aid in refitting.

Stuart

Yeah you have nothing to worry about! Yeah clean off the dirt and oil deposits and reuse it, it should be ok. I can see it has a slight flat on it. as long as its still 'rubber' like you should be fine. I reused mine and they were in great condition.

Out of interest, is there any manufacturer part numbers on the new CPS? I notice it does not have the BMW logos and part numbers like the original, this was bought from a BMW dealer correct?

i bought it from a guy who sells BMW and Mercedes parts only. His part # matches the BMW part #12147518628 from the dealer. I bought a CPS for my Mercedes E320 and I took it to the dealership, they verified that it was MBZ part but it didn't have the MBZ logo either. I hope it is the same story with the BMW CPS I ordered.

In any case, I replaced both CPS on the passenger side. Now I am getting P0365 Camshaft Position Sensor B circuit bank 1.

Is this the code on the driver side? I am so stressful trying to fix this. Sorry guy.

Please let me know what the above code means?
thanks

Double check installation and plug connections on bank1, pass side. Worse case you got a bad one. Are your symptoms still there? Did you clear codes?

yes i did clear all codes. after i replaced the lower/left cps (standing from the front of the car) the car ran fine still. Until after i replaced the top/right cps, then the problem occurs. would the code indicate which one? lower/left one or top/right one? for my knowledge, which one is for the intake and which one is for the exhaust?

Also the car ran after replacing bottom with no codes? Then top threw a code?

Sorry guys been asleep here in the UK!

Yeah your is LHD, Bank 1 will be passenger side head. Sensor B should be the exhaust sensor, that's the one to the furthest left lower down like mentioned above.

What was the condition of the plug when you removed it? Did it have oil in it?

What was the original fault code?

Stuart

I will have to check again, but I always thought these sensors were the ones on the front of the heads.. those connectors in the back are caked in oil IIRC.

wow although my work is not a success but knowing there r guys from the UK are willing to help, i m happy.

the darn plugs are so hard to get to on the passenger side. my cousin who is a toyota master mechanic looked it up in the computer and it advised a mechanic to charge 30 minutes to replace a plug. if i knew that, i would let the expert do it. on the other hand, if i had to replace on the driver side, i would agree.

oh well, that why i m not a mechanic.
cheers

Dont be so discouraged, reaaaaally make sure that they're seated properly and make sure there is not oil in their plugs. (Look proper use of their there and they're! Lol) i guess especially the exhaust in your case

Camshaft and eccentric shaft sensors are at the back of the cylinder heads. The connectors at the front on the upper timing chain cover are for the VANOS solenoids.

I would suggest swapping sensors from bank 1 to bank 2, then see if the faults follow the sensors.

There are a few benefits with owning a V8..... The power, the noise! And the ability to swap sensors to different banks to diagnose faults!

quick question please guys: when installing the cps, since there is an o-ring, I didn't make any effort to push it in bc of the space issue on the passenger side. I just placed it in and tightened the screw hoping that would push it down. Would that be the cause of it? You know what I mean?
Thx
