Got a strange problem with our 2007 W639 Vito - the cluster display has started 're-booting' (for want of a better description!) intermittently while driving. It goes blank, then displays 'no data', then comes back up with the miles/mpg/time/speed stats. all reset. I *think* the red SRS light on the dash comes on momentarily, but not 100% sure of this. The main odometer is OK, and the trip mileage on the odometer screen is usually (but not always) retained. So it's an annoyance rather than the end of the world! It's been doing it for a month or so, the interval between occurrences is quite variable ... sometimes 500+ miles, other times it can happen again after 5 or 10 miles. The van was in for service yesterday (main dealer) and they couldn't identify the problem. Apparently there were some errors logged on the cluster which they cleared, connections and wiring looked OK, and it was fine on a road test. But then it reset itself twice on the drive home I know we have a few other Vito & Viano owners here - has anyone else seen (or heard of) this problem? Presumably it's either an issue with the cluster unit itself or the wiring loom somewhere.
