I have a 2010 mercedes engine Cdi with PDF filter/burn cycle.
Car has been just suddenly slowing down occasionally for the last month, roughly once a week, requiring me to pull in, switch off, wait a few minutes, start up and away again as normal, til it happens again.
Then this week the engine management light came on and checking with my code reader, just the one fault code........
P0299 Supercharger/underboost.
Can anyone expand on the fault and what it will take to sort it, thanks.
In the meantime I have reset the code, and engine management light is now off. Car runs fine most of the time, till it suddenly slows down.
