Hi everyone and thank you in advance for any advice offered.
I own a 2006 CLS 320 (diesel) with some peculiar running issues.
1) Intermittently - On acceleration there is no acceleration for the first 1cm of throttle depression. Only a knocking noise from the engine. Pushing past this the car...
I'm having a repeat problem with my CLS and was hoping someone may be able to offer me & my local dealer some guidance or further ideas into what the cause may be:
Engine runs slightly 'lumpy'
Gear changes 1/2/3 are harsh (not as smooth)
Engine appears to be running...
