P0015 - Cam Position Sensor

I don't have an SES light on, but I do have this trouble code

B Camshaft Position Timing Over Retarded - Bank 1

Is this what it is refering to -item 6?



Which is B Camshaft - Bank 1?


Is this typically a sensor problem or should I be looking else where?

(I cleaned the two solenoids out with compressed air a couple of months ago when I was doing the VCG but there was no noticeable debris inside.)

I had an SES light appear this morning. I have over 97k miles on my 2008 X3.
I stopped by Advance Auto at lunch to have the code read.

The returned code is:
P0015 - Exhaust (B) Camshaft Position Timing Over-Retarted (Bank 1)

I found this over on the e46 board. Look at post #6 and #8. The VANOS seals may be the issue.
https://www.bimmerfest.com/forums/sh...d.php?t=427473

I am not going to go off of the generic P0015 code and just start replacing parts. I just ordered a BMW specific ODB reader that should provide the amount of detail that I need to properly diagnose. Since my light just went off, I might hold out until my new reader arrives. If it reappears and it makes me nervous, I'm going to stop at my local independant German import repair shop and have them take a look.

Good luck

Hey Al, thanks for the link. Certainly lines up with my symptoms.

It seems like B camshaft is the one on the exhaust side. I just got back from my indy shop and they reported a '2A87 Exhaust Vanos, mechanism' code. So a set of seals needs to be ordered. And I just had all that apart doing the VCG

OK, education time.

I have a N52, so I presume the engine in the E46 link is an M54, so the two vanos units look different.

The VANOS solenoids valves in my N52 are part 1 in this realOEM diagram, yes??



There are two of them, although that's not really clear on the diagram.

If, so, I did the o-rings earlier, so it is either the valve itself or the connection to it. I understand that the two valves are identical, so is it reasonable to swap the valves (but not the connections) and see if I get a P0014 instead of P0015, or is that not a wise move?

Just to clarify my first post: my SES light comes and goes. Sometimes it is on, sometimes it is off. Whenever I check the ODB codes there is always a P0015 "trouble" code, irrespective of SES. Sometimes I also have a "pending" P0015 code simultaneously.

you only have bank one as its a I6 engine..

over retarding has to do with timing advance.. which is controlled by Knock.

Id look in to your fuel system before i go chasing cam sensors...

and as soon as the Code is generated there should be a pending...

pending are generated by live codes

Update.

I swapped the two solenoids over but it didn't make any difference, at least not to the OBD codes nor the driving experience. I cleaned them out with compressed air and kept them separated. At the time I was 100% sure that I knew which was which, but of course now that they made no difference, the seed of doubt has crept into my head.

Then I got thinking about Burning2nds comments about the fuel system and I recall another poster mentioning changing fuel brands. I normally use Kroger (supermarket) 93 (R/M) octane, but as an experiment I filled up at the Shell station next door, again using 93 octane. Checked the codes 20 miles later and P0015 was gone.

I am now 150 miles into this tank and it hasn't returned, and when it's dry I will refill with Kroger 93 and see if it returns.

So what's the difference between Shell and Kroger fuel. I thought it was just cleansing agents etc. Both gas stations are right next to each other and both are constantly busy

The camshaft position sensors are known to go bad on N52 with high mileage. Symptoms include odd idle, odd rpm flux. There are two of them identical that will go bad (intake and exhaust side). I simply replace both if one goes. I placed an order for this below just this week:

2xBMW Camshaft Position Sensor - VDO 13627525014 $180.88
2xBMW Camshaft Position Sensor O-Ring - CRP 12141748398 $1.90

You can find the parts easily on FCP EURO.

DIY here, with difference being how you take off intake cowl on X3

Yes, the E46 had the same issue. Luckily its a very easy swap out.

Update.

Well, my P0015 code has stayed away and I haven't had a SES in a couple of weeks.

I had the car in at an Indy for another manner and they pulled the codes and got an "Inlet Vanos" code, following my swapping of the solenoids, following the Exhaust Vanos code earlier. I reasoned that the code had followed the solenoid, and even through I had cleaned it, it was still stuck/faulty. Bought a new one and installed it (replacing the top one - correct, for Inlet ??) However it hasn't made any difference to the driving experience; still is jerky when coming to a stop. Is there anything I had to do (programming/initializing etc) that I need to do to "tell the system" that the part was exchanged?

This was during the first fill of Shell gas. I have refilled with Kroger gas to see if the P0015 reappears, but it hasn't yet.

How old are your spark plugs? If you have over 80k miles on them, they could be going bad. Old plugs can cause idling issues which in turn cause jerkyness when coming to a stop.

What do you mean by jerkiness? Does the whole car jerk or is it just the engine? Does the tach drop or hunt when you come to a stop?

I would say that the tach hunts a little.

The car feels jerky but it is hard to say whether the revs hunting cause the tranny to shift roughly, or is it the tranny hunting that causes the tacho hunting. I just changed the tranny fluid (but not the filter yet) as well as the xfer box fluid.

But as I was getting codes for the VANOS valves, I was trying to clear those up first. (chicken and egg etc)

Same intermittent SES issue P0015

I have the same code and it comes up every time I am on the highway going at a constant speed for more then 10 minutes.

Once I get on local roads 2 to 3 start stop light is gone.

Some times I have experienced that there is jerk when stopping at a light and the same code appears.

On speaking to Indy car tech he said tha the vanos seals need to be replaced and costing over 1k.

Should I replace the solenoid and see if it fixes the issue.
