P0010/P0017? Cam solenoid?

[ptschram]

New client, truck runs great, but the CEL comes on periodically.

Scanned it and got the above codes, but can't find much guidance on the resolution, except for murky reports that replacing the cam control (VANOS) solenoid resolved the issue.

Anybody got a definitive opinion on this one?

TIA

I assume this is an 03-05 with the BMW m62 engine. Camshaft position sensor(s) failures are common and is the likely reason for the code. It was the first failed part I had to replace on my BMW. ONLY REPLACE WITH GENUINE BMW/RR PART! Many, many people have tried to use aftermarket, only to have the codes reappear (including myself). It takes 5 minutes to replace the sensor. I think 010 is the driver's side bank. The 017 should be a rationality code for the sensor disagreement.

While I appreciate your independent confirmation of what I was thinking was the issue, Land Rover and BMW don't make those parts, a third party, tier one supplier, makes them for them. I worked for one of those companies, you wouldn't believe the parts we shipped in OEM boxes.

I understand how OES works. You need to use an OES part. If not, you will be explaining to your client why the code came back on and why you are having to go an buy another part. I can tell you that the O'Reilly's sensor I bought (FEBI maybe), which is the identical aftermarket brand part, did not work. The BMW sensor I purchased from the BMW dealer has worked with no CEL for 20k miles. I think it is a genuine Bosch part. Unless your business plan includes charging your customer for multiple repairs, make sure you get the sensor from a genuine OES supplier.

Do a search on Bimmerforums.com and see how many failed aftermarket CPS sensors you read about. There will be many pages. Good luck to you and your client.

It is possible that the VANOS selenoid has failed, but you would be getting additional codes. I think it is unlikely. The CPS is the most likely culprit. One way to test it without buying a new one is to swap sides (there is a driver and passenger side) and see if the code triggers for the other bank. This is how I confirmed mine had failed.

Thanx for the input, it did the trick. Looked like someone had been there before me as the cable was twisted, crimped and strained.

Put the new one on (man, are they easier to replace than on the Rover V. Cleared the codes, test drove it (had a great time doing THAT). CEL didn't come back on in about 40 miles. I think it's fixed and can go home now.

PT what part did you replace I could guess but i would rather hear it from you, thanks!

[ptschram]

Camshaft position sensor.

[Mrmerlin]

Thanks PT where does the camshaft position sensor go.
I thought the other posted was suggesting to replace the crankshaft position sensor
but you replaced the camshaft position sensor?
are there two of them?
this is not the Vanos solenoids?

[ptschram]

In spite of my best efforts, seven miles after delivery, the CEL came back on.

The CmPS is on the front of the head, held in by a socket head cap screw, the cable is beneath the acoustic cover.

I'll let you know what the code is when it comes back later today.

I was chatting with a BMW shop owner in CA and he mentioned that when the M62 engine starts throwing engine codes,
that usually replacing the Vanos units will cure the issues,
he said they usually go bad due to oil not being changed as frequently and they can gum up and internally wear out.
Fortunately they are easy to replace he also suggested to replace the oil valves behind the vanos units as they plug in easily when the vanos unit is slid out.

Could be. This truck only has 55K miles on it and the inside is pristine. I've seen many of them that were abused and ran fine. This one appears to have been pampered and look what we get? Typical Rover!

[BMWRover]

Did you buy BMW or aftermarket?

Genuine Land Rover in a pretty green and white box. Even said BMW on the side of the part.

Ok. I think your guess at the Cam Selenoid is good. Do you have access to a diagnostic scanner rather than just a generic OBD code reader? This would help you confirm. If you are not getting rattle from the VANOS unit, the selnoid is another good place to look.

You will need a special thin walled deep pocket 32mm socket to get the selenoids out. It's almost as easy as the position sensors. The RAVE manual has the procedure.

Update: The truck returned today (some clients are far more gracious than others, man do I like the nice ones!) and provided me with P0010-not present and P0017 Camshaft/crankshaft out of sequence.

I reset the adaptations but was not able to run a VCC test for whatever reason.

I'm hoping my scan tool has the functionality to reset camshaft adaptations, or that they can write a script to allow me to do so.
