Air suspension goes up and down each time I stop
Hi guys. I hope my posts don't make me seem like too much of a whiner. I love the car but am just disappointed at how often this thing needs repairs. The air bags have about 20k on them. The pump (Mercedes) works great. Each time I stop at a stoplight, the front of the car adjusts itself. It usually goes up two inches or so, waits a second, then drops itself down slightly. Sometimes it goes from side to side. Does anyone know what this is? There are no warning lights and the mech can't find a code when running the Audi/VW VAG diagnostics. Thanks for your help.

Sounds like the normal self adjustment of the suspension. The front end probably isn't raising then lowering...It's raising then the rear end is adjusting which gives the feeling the front end is lowering.
The car height is adjusting all the time. What ride height setting are you running in? If you're in the 3rd setting, the adjustment will be more drastic than if in the 2nd setting. Once you drop below a certain speed, the car will raise itself back up to the 3rd setting.
If you're running in level 3 and it bugs you (it bugged me), set it to level 2. There will be less travel up and down.

Mine does it too, but subtly and that drives me crazy because I am never sure if it is really moving or my imagination. I do think 2 inches seems extreme, but how much it actually moves is hard to really measure

Can you get me the part # or the year and model of Mercedes for the pump you used. Mine may need replacing and I understand the Mercedes unit is more reliable and economical.
Thanks,
Joe

The Mercedes pump is the EXACT same pump as what is in the allroad, only cheaper when
you buy it from them because there's a lot more Benz's with air suspensions. You have to rework some of the tubing. Its a very easy repair. I paid $330. Purchased from Import Motors Bay Area on Ebay.
