Hello I’ve already been looking for in the forum – but I found only descriptions for cars with Airmatic front and rear. My car only used the air bellows in the rear. Front springs – 320 cdi – 2006 – 4matic In any case it is quite wrong in the back. If I turn on the car, then it drives up to the right and left at the same time – that takes about 1 minute – nevertheless the driver’s side remains lower than the passenger side. I once had a Lexus with air suspension, so I also had so a problem and there you could change something under the car with a screwdriver and wrench – each with each tire – and say so to the air suspension – where it should stand higher or lower. Is there something like that here too? Strange is that both sides drive up at the same time – and the difference between both sides remains the same. I am happy about help and tips – if I need a new air bellow – you always have to exchange both sides together? le, which you can recommend? Thank you!!
