How does one address P0014 (DTC 104) & P0011 (DTC 103) ?
 

My 3.0i E53 has the "Service Engine Soon" light on. Connecting an OBD2 scanner I see P0011 and P0014, both associated with the VANOS, one for the intake side (P0011) and the other for the exhaust side (P0014).

Running INPA and PASoft (BMW Scanner 1.4), I see DTC 103 and DTC 104.

So, I now have "rebuilt the vanos" by replacing the vanos o-rings (this kit) and cleared the codes, but the codes came back after starting the engine a 2nd time.

Anyone have any ideas of how to fix this? Could it be that both solenoids are stuck?

BTW, the INPA live data for the VANOS show the information in the attached jpg (same values seen on PASoft). None of the values seem to change, not even while driving. Are the position values supposed to change? Does this mean the camshaft position sensors that are near the VANOS (or on the VANOS housing) are bad?


Thanks!

Almost always when you have cam alignment problems it’s the cam sensor.

Get OE they are stupid sensitive and the aftermarket brands will give you fits because it almost never happens where a code points to the sensor itself.

The values should change but won’t charge much without load I check vanos operation while driving and best if you can graph the requested vs actual angle.

@andrewwynn: Thanks! I assume you are using some software to create a graph live as you drive. If so, which software is that? I have not seen that capability on INPA nor PASoft.

I use either my foxwell nt510 scanner or my wifi OBD dongle and software.

Torque I think is the Android version I use iPhone so I use either OBD Fusion or dash command. (oops just realized those phone solutions are level one obd they work great for o2 sensors but won't track BMW level two stuff.

Nt510/520 will graph two things at once so it's great to show the requested v actual camshaft angle etc .

It's exactly how I figure out if the cam sensors are farbled. Almost always when CPS is forked, they soft fail and give you every type of code OTHER than something related to the CPS.

With the V8 you can swap them to see if the problem moves banks but there is no guarantee that will help. They are so sensitive the difference in the reluctor wheels can make the problem stay on the same bank.

When I'm suspecting cps I bring up requested vs actual cam angles and drive. The problem usually presents for me and it's pinned down CPS culprit at least three times.

I bought the intake camshaft position sensor from FCP Euro. They say it is OEM and I hope it is because it is just a bit over half the cost of the BMW branded sensor. I'll replace it and see if that makes P0011 (DTC 103) go away.

While I wait for it to arrive, I am gonna clean the intake solenoid and see if that does anything. I should have done that when I had the VANOS housing off the engine. argghh...

Are you sure you got the vanos timing correct? Did you buy the timing tool for the M54 engine?

Here's the correct to set the vanos timing.

I did not touch the camshaft nor timing chain, only removed the vanos housing, so I did not think I needed to do a timing adjustment. Is it needed anytime the vanos housing is removed?!

Yep
