Hi,

Recently got a CPS code P2034 and another code P20A2 on my w211 e55.

P20A2 when ZAS is turned off,some cylinder exhaust valve not work.;GERMANY

Does anybody know if the second code is caused by the faulty CPS or is it a different problem altogether?
 
No idea about your codes as the 2nd one is generic and not a STAR code that I can see. Do you get the typical CPS fault symptoms?
Difficult or impossible to start when hot? Allow the engine to cool down and it restarts?
 
Its definitely a CPS problem as confirmed by the code. The car just stopped while I was parked on the road (fortunately) with the engine running waiting for someone. It managed to start a few hours later no problems.

I guess I will replace the CPS and see if both codes clear.
