Hi All
My W220's airmatic started giving the Airmatic Car too Low warning every now and again on the way to and from work, it only seemed to do it going along the lanes, it was fine around town and on the motorways but then it was getting more and more often and every day, I suspected the compressor and planned to get and fit a new one, last thursday not one warning to or from work, went out thurday evening and was fine on the way there, came back to the car and the front was on the ground, started it up and it rose a bit but within 1/2 mile of driving off it was right down, took it VERY slow and got it home.
Bought a new (used) compressor and fitted it last night, started it up and she leveled up, set to high and within about 15 seconds the Vehicle rising went off, cool I thought, sorted, set the level to normal and she lowered.
I left it running while I put the tools away and BONG Airmatic too low appeared again, looked and the NSF is down, all the others are ok, set the level high again and up it came, back to normal and it was fine for about 30 seconds then BONG again.
I can see the NSF dropping but cannot hear or see any leaks, no hissing from the strut top or leg, the level sensor must be working as it stops at the right level and warns that it is low.
Could it be the valve block leaking internally, I am sure I read somewhere they have a non return valve somewhere, could that be faulty (if so where is it)
Any help would be great.
