Beeper goes off in the middle of driving - 6/29/2007 4:32:26 AM    prandis   Posts: 4 Joined: 7/23/2006 Status: offline I drive an ML 320/2000. For some time now the problem occures that the car internal beeper goes starts beeping in the middle of driving. There must be some kind of a shortage in the electrical system. 4 or 5 controll lights turning on - the first three on the left ( ETS, ABS and aother one and the Emergency brake control light which probalby triggers the beeper) I have to stop the car, turn of the engine and hope that the control lights turn off after starting the engine. Now more often this happens. Does somone has an idea what that could be? Your help and suggestions is highly appreciated. Thanks Peter _____________________________ ML 320 / 2000 Post #: 1

I took it into the dealership and they said my sensor main unit (CPU) is broken and will cause the "all system failure" beeper to occur.  The CPU is going to cost me 3,000, I am currently waiting for a second opinion.  So far (keeping fingers crossed), I have not experienced the beeping in a while (4 months), I've tried every scenario possible.  It tends to occur more often when I use my A/C and the engine is VERY warm (summer time). I am contemplating an upgrade to the ML320 CDI - the diesel engines have come a LONG way !!  Used to have the 90's diesel version. (in reply to prandis) Post #: 6

I didn''t have the problem during the winter time. Now it''s summer and warmer it started again. I looks very much the same what rbr2007 experienced. My ML has now 140000 miles and runs well, besides the beeping issue. I really would appreciate your input. Thanks!!!!!!! __________ _____________________________ ML 320 / 2000 (in reply to MBPrincess) Post #: 8
