Hi
New to the forum and realise there are many threads already on the air suspension and Ive read a few but cannot see my issue and to finding an answer.
I have a 2011 E350 Estate S212
I hit a pot hole last night, and not long after the ride became quite bumpy and not so smooth.
I nursed the car back to my house and looked at the wheels and noticed the car is sitting higher over the rear right/drivers side wheel.
The left hand side rear wheel seems to be in its normal ride height, but the right hand side rear arch seems to be sitting higher, there is a much bigger gap between the top of the wheel and the wheel arch.
Im guessing there is an issue with the air suspension but not sure where to start.
Is there a reset that I can do manually with out a diagnostic kit?
Any suggestions would be appriciated.
 
Check the level sensor(s) are still attached and undamaged.
 
Had a similar issue with my Cayenne , turned out that a level sensor connecting link had sheared thanks to hitting a pothole so the suspension defaulted to the fully extended position at that particular corner.

Thanks for the replys.
I think I need to get it booked in to get it up in the air.
The level sensos sound very plausible.

It should be visible whilst the car is on the ground , especially if it is sitting high at the moment.

Top man,
And a brilliant little vid provided there
lets hope that is the problem, as what the person in that video is saying that if the arm is positioned down it will push the suspension upwards. im hoping thats all it is.
Many thanks
 
Quick update
It was exactley as suggested that the link arm to the air suspension lever had snapped.
Link arm has been repaired as a temp fix and I have ordered and received some upgraded link arms from ebay with metal inners.
Hopefully they will be more robust.
Many thanks for the input and suggestions.

Was it these?

It was.
I bought a pair and had both replaced..
Quite lucky really as when the car was put in the ramp to have them changed the mechanic only touched the other side plastic link arm (the side that hadn't yet failed) and it fell apart.
Good quality replacement parts.
