Ml airmatc problems
 

Hello all
I have a 2006 320 cdi Airmatc , noticed that if the car sat for more than 3 days or so I would find the front end dipped, lowered , now 3 months later it can happen in about 24 hours , ok I talked to Mercedes here they want to keep the car in few days to evaluate where it could be the problem , strut , compressor , etc etc , strange thing thou when I have the car raised up to the max , and leave it over night it stays up !? In normal ride height it will dip down slowly over night ? Strange ? Always when I start the car it will raise into position, did I make any sence here ? Suggestions welcomed :)
