W204 200k - Fault Codes 3539 & 2188

[l.d.r]

Hi there,

Newbie on this forum here.

I have a 2008 C-Class 200k (1.8 kompressor). The engine management light recently came on and the car is now underpowered and struggles to go above 60 on the motorway.

I took it to my local dealer and they found the fault codes:3539 - the boost pressure deviates from one the specified value, and 2188 - the mixture (cylinder bank 1) is too rich at idle speed. My handheld scanner also picked up 2263 but this was not recognised on the dealers machine.

They have not yet diagnosed the problem and want to charge for a further 1 hour of diagnostics to further investigate. My local specialist seems to think it may be a MAF issue, but is unsure if this would throw the 3539 code and wants to spend some time investigating this.

Any help on what the problem may be would be much appreciated.

Thanks,

Lee

Try disconnecting MAP sensor and see if its still under powered

It could be so many things causing this issue.

MAF's on this engine are usually very reliable. They do suffer from oil leaking in the engine loom casing a whole manner of issues. Needs a Star and some time to work out what is happening. Remember codes are only half the info.
