Hello all, I know the C155664 code has been discussed before but I didn't find anything for C151E1C. The C155664 code was stored in the system but the C151E1C code is current and stored.

When I start the car I get a "Malfunction" message with an arrow pointing up inside a car silhouette. I can hit "OK" and it goes away. The suspension button on the center console does nothing. Nothing sags when it sits over night (at least not that I can notice), and I can hear a very small amount of air being released after I park the car.

Can anyone give me a place to start? I checked the fuse (7.5 amp? seems small) but haven't replaced the relay yet.

When scanning the car I get:

C151E1C (stored&current) "left front level sensor has a malfunction. The voltage value is outside the permissible range"
C155664 (stored) "The Compressed air sensor for the system pressure has a malfunction. There is an implausible signal"

2010 E63 AMG

Thanks in advanced and sorry if I posted in the wrong spot.

 

This may help...

 

Thanks!

I had read that before but it doesn't mention the other code. Also, the Compressor code isnt current, its only stored.

I changed the oil last night and while it was warming up I noticed the car would let our air, then the compressor would run. this happened every couple of minutes.

I want to disable the system until I figure the issue out (that way I dont burn out the comp), how would you guys recommend I do this? pull the fuse?

 

Did some more research and you cant just disable the system.
