Hi I have an SL320 which is 4 years old. From new it has had an intermittanf fault. When driving along, the radio/cd goes dead and a message comes up on command screen saying'system unavailable' it also wipes out my heated seats and wipers. Sometimes they are out just for a few seconds and sometimes a few minutes and it only happens now and again.
My local Merc dealership have had it in a few times and replaced a special battery in the boot and some controller unit but the problem still persists. They have it in again now but still cant find anything wrong. Has any one else come across this problem?
Thanks
Susi
