I have a 2011 Countryman S All4 with 80k miles that has been unreliable recently.
It has had a brand new turbo and wastegate, turbo pressure regulator, turbo diverter valve, exhaust cam sensor, spark plugs and trans service. Since then, it did about 500 miles without issue, then suddenly dropped into limp home mode and Check Engine light on.

I pulled the followed fault codes:

2DD0 Valvetronic System: Control Deviation Warning Threshold exceeded
2DCE Valvetronic System: No Adjustment Possible
2C57 Charging Pressure Control, Plausibility Pressure too low
2CB3 Wastegate valve, Activation: Suspicion of fault in Wastegate Activation

I have googled all of these with no conclusion. Does anyone have any ideas which troubleshooting steps to take?

 

Hi, I´m having two of your valvetronic codes: 2DCE and 2DD0
Were you able to fix the problem, if so, what was it?

 

I believe I fixed it. I replaced both valve solenoids (part number 11368610388) about 3 months ago and the problem has not returned.

One of the solenoids was missing the wire mesh filter, so that has probably been vaporized in the engine somewhere.

 

I believe that the original solenoids did not have the mesh filter, I don't think it was vaporized.

 

One of the old units did have a mesh, one didn't, and otherwise the units looked identical.

 

Hey Spawneywhippet.
I'm over in the UK and saw your posts regarding the above. Was your solenoid replacement a permanent fix please?

 

Yes, that was a permanent fix. However it took me a long time to find the cause of '2C57 Charging Pressure Control, Plausibility Pressure too low' warning. In the end, replacing the high pressure fuel pump was the fix.

 

Thanks very much for coming back to me on it.
Not doubting you for a minute but before I start throwing money at it.
I can't figure out what the valvetronic codes I've got have to do with the vanos solenoids that you replaced, as they seem to be unrelated systems?
Also, we replaced the mechanical fuel pump a couple of years ago and never had that last code that you had.
Just to help, I've got all four of the same codes as you, but the fault has gone since I cleared them out.
if it comes back I'll have to start somewhere.
Any ideas?
Thanks
