Hi all,
I've returned to AMG ownership after some years (sorry, I know there's no excuse!) and have got a 2001 W210 E55 AMG.
It was running as smoothly as it should at first, if a little down on power. However, after a couple of weeks it started becoming jerky on mid throttle openings, followed by uncertain/rough gear changes. This problem got worse and the engine management light appeared. The part load throttle opening jerkiness got worse to the point where the power was either on or off: only gentle throttle use or pedal to the metal would work.
The 'box had signs of an oil leak so as a precaution I've had the 'box serviced and signed off as solid. The engine diagnostic codes were read and suggested a problem with the MAF sensor (will add the codes to the post later, don't have them to hand).
I've changed the MAF (to a non Bosch part - for now) which seemed to work after I gave the car a good hard run. However, the problem/warning light came back on at the next start up.
A couple of rubber seals and a plastic collar around the MAF were perished/broken respectively so I changed them as a precaution to ensure the parts had a good air tight seal.
Whilst I had my head under the bonnet and the engine running, I noticed this part (see pictures) started clicking in the way a faulty/failed solenoid does, about a minute after start up. I think it's on the air lines into the engine.
Can anyone please tell me what it is and if they feel it may cause the symptoms I've described?
Thank you!
