W204 C220CDI Map Sensor(s)

[Plitty84]

Good evening I have a 2013 W204 CDI with currently has intermittent engine light on and lack of power no kick down etc. Fault Codes:
P2279-06
P0299-00
P2279-62

I’ve had the intake system checked for leaks etc which garage reported as ok, they recommended to replace the EGR valve due to possible internal air leak which didn’t cure the fault.

Now they are recommending to replace the map sensors which may have conflicting information causing the fault. Problem is I thought there is only one map sensor? If there is two are they located close together?

Any help/advice is greatly appreciated, many thanks Andy

Sounds more like a boost leak from the intercooler pipe, quite common. Have you done a smoke test as this will pin point the leak for you.

Thanks for your reply. The workshops report stated they checked hoses, but whether or not they did a smoke test I don’t know.
