when I use my automatic key to lock the doors fog lights flash, alarms are going off not sure what's happening.
battery went dn, I got a jump. know when I lock door fog lights flash. on 2005 Mercedes-Benz S500 4MATIC
Pretty sure this car uses an additional battery for accessories.That may be going dead.I would take it to a shop that is equipped to work on Mercedes.They should have a Xentry diagnostic tool.(We have 2 here)Some settings may need relearning.
Thank you for your response, I do plan on taking it to a Mercedes dealership. I also have a problem with squeak in the front when I hit a bump, I just wanted to have an idea of what I was looking at before I took it to the dealership.
