EGR/Turbo boost issue
Newbie from England here, hope I'm posting this in the right place.
Been trying to figure out with very limited resources a problem with my w204 that happened the other day. I was driving along fine then all of a sudden loss of power and spluttering of the engine.
Pulled over, cycled the ignition, rough idle still and went into limp mode 😔 managed to get it back on the drive.
I've got a basic reader and got 3 fault codes:
P0236 - turbocharger boost sensor 'A' boost range/performance
P0299 - Turbocharger underboost condition
P0401 - EGR 'A' flow insufficient.
Has anybody had anything like this before? Is this common? And has anybody got any ideas what it could possibly be?
Cheers
