W205 Acceleration Issue (Restricted Power)
Will take all the help I can get.
When accelerating these seems to be a judder of power as if its being strangled. No engine light or signs of a boost/air pipe leakage.
It started of as gear change issue with a strong jolt and judder before going into limp mode, turning the engine on and off fixes the issue (crankshaft sensor). That issue has gone and now the new issue is that it struggles to find the power and sounds like a horrible purr with limited power.
Boost sensor?
Air Sensor?
Vac Pipe?
Boost Pipe?
Coil pack?
Any advice is much appreciated.
Cheers
