I have 2006 S350, just had yearly maintainence done, they changed the steel air valve covers to plastic stating that steels ones cause interference wih air pressure monitoring system. So like 2 days after the service, air pressure warning comes on. I check air pressure, it is bit on the high side, like 36 or so. anyways I resent the warning, reactivate the air pressure monitoring system, I was going to reduce air pressure next evening, in the morning while going to work, all of suddent everything electronic shut down in the car, like command, display lights, car did not shut, i was close to home so was able to drive back, transmission wans;t even shifting, nothing electirc worked, like even garage door opener. so I tunred it off and went to work on other car. now, next day, when i try to start the car, key won't turn like it happens when stirring wheel is locked but it is not. no lights come up, even car key is open and close locks is not working, the car is in kind of a shut down/lock down mode, i did not get any warming on the dislay before this happened.
Any ideas? Thanks for the help.
