I have Mercedes E class 320 CDI. I left it parked for a week then when I started the engine Many Error massages started appearing on the board including, SRS, Display faulty, Key sign and the parking sensors were beebing intermittently, the CD unit stopped working. I drove the car and then when switched it off and left it and remotely closed it. The light inside the car came on and sometimes was flashing. The only way to overcome all these faults was to disconnect the battery for 10 to 20 seconds then everything would get back to normal and I drive it with no problems, however when I switch it off and leave it for a while and return back same problems would reoccur again.
Could you help please. David
