s500 airmatic problem
My s500 for the last few months had the malfunction message coming up from time to time, the car was though on correct level, only if would have it parked for a few days - the rear passenger side will be lowered. After start of the car it would go to normal level.
Recently we had a drop in temperature down to 0 C , and in the morning the whole rear was lowered and was not going up after the start - the warning message 'car too low' would appear on the dashboard. Went to check it at the garage - 3 codes found. 5288 - the pressure systems leaks, 5284 - fault in airmatic central reservoir charge valve, or pinched pneumatic line between the compressor and central reservoir. 5289 -central reservoir for airmatic leaks.
I drove home (still with lowered back) , but on that day it was warmer and suddenly the car got back to the correct level randomly.
Now is cold again and the back will get lower and not rise again.
Can anyone suggest what would i need changing?
Many thanks.
Year 2006.
Can it be the pump itself as the problem? One of the mechanics suggested to replace it....
I am just thinking that it works from time to time (dependent on weather) it cannot be the pump.
