Hi folks. My 2014 320D touring Efficient Dynamics has suffered ever since the EGR cooler replacement circa Dec 2018; throttle hesitation when filtering in traffic; in the 1200rpm to 2000rpm area; prime example, entering a roundabout; gently foot on gas, nothing; then BAM! Kicks in with a sudden...
So my N54 135i suffered
Rough Idle / Whole car shakes
Blackening of the exhaust / Carbon etc
However only once did engine light / limp mode activate
Only twice did dealer spot a code, an old code
So under Warranty the Injectors have all been replaced
The HPFP replaced...
