Over last few months on 5 or 6 occasions whilst driving the car exhibits multiple electric faults that include: Speedo & Rev counter stop working, indicators stop working, electric windows & windscreen wipers won't work, engine cooling fans come on full power (I think).
If you stop, switch engine off, then restart - car starts and all is fine.
Been to 3 garages, first fitted new battery - which made no difference, then it went to a Merc main dealer who said it wasn't showing any faults. Then found a Merc Indie who said Star didn't show any faults and suggested a new front SAM unit was possibly the common thread, unfortunately this hasn't fixed the problem.
Its going back to the Indie for another look, but any pointers would be grateful.
