limp mode

[Smgimports@live.co.uk]

Hello everyone,

Can someone please help me, i have a c220 cdi 2004, it keeps going in limp mode.

This problem originated after i replaced my 1St turbo which had the shaft broken. It started going into limp mode a day later it was replaced. so the mechanic advised me its the actuator switch, so i replaced the whole turbo& actuator switch which i got from a running car, still i had the same problem.

But every time i switch my car off and on it works for a short time, then i have the same problem it doesn't go past 3000 rpm
the actuator switch moves when you turned the engine on.

Now i have been to number of garages and everyone telling me different things to change Eg lamber censor.

also i have the fault codes which is:

2510001: check component Y100/1 (right charge pressure positioner signals fault).

2195004: heating check component G3/2 o2 censor of cat signal line is interrupted.

Thank you very much for your help.

the code p2510-001 strongly suggests a turbo fault, either sticking vanes or actuator, or even possibly a short on the PWM signal wire to it - but unlikely.

Im with Alex. Did you replace with a new turbo? Or did you get a 2nd hand unit?

Thank you very much for your reply's much appreciated.

I Reconditioned the 1st turbo, and the second turbo with the actuator switch was second hand from a working car...

Have you any suggestions what i should do??

Thank you.
