HELP: 2632-8 "Charge Pressure Control" Too High W211 E220 CDI 2004

Hi

Anyone help with this fault code?

2632-8 Check system: "Charge Pressure Control Charge pressure is too high"

It's on a W211 E220 CDI (OM646) with no DPF fitted.

No problem with driving, car goes as normal with no limp mode or malfunction on dash.

It's the last fault shown after I did the ABS impulse rings etc. so is rather annoying having 1 fault code when the car drives as normal.

This code is triggered by MAP sensor.pressure is controlled by turbo actuator .

Mine has the same code with but w/o any problem.This is recorded in the moment when turbo blows air .it is just a moment.

Thanks, yes car goes perfectly.

I may remove the air pressure sensor and have a look at this and the turbo actuator.

 

[4life211]

Do not remove the air pressure sensor ,because it sends the signal to ECU and this controls the turbo actuator

I'm not going to run the car like this.

Will have a check over these though next time I have the engine cover off.

OK.Don't forget to keep in touch.

Removed the MAF/MAP sensor housing, blew it out with some compressed air, cleaned it up a bit, refitted, checked all connections then cleared the error.

Has not shown again after a few days so maybe just a gremlin.
