I have been experiencing an intermittent electrical 'short' for the last few months, where the whole electrical system would very briefly turn off and then flick straight back on again. This only seemed to happen in cold conditions, and when I'd got lots of things turned on (heated font/back windows etc).
I noticed yesterday that during one of these 'shorts' the odometer must have reset my total mileage to 00000. My 61 plate 1.6 (petrol) had done 41,000 miles at its last service, now it's reading 5454 miles.
I took it into my local dealership for a service and mot and told them the issue, they said they have never seen it before and cant do anything about it. My new mot now has the 5454 miles recorded. The mechanic looked in the ECU and it has an internal record of the correct mileage (before the fault) so he has written this in my service book, but I think I'm going to have a hard time when I come to sell a car with 'dodgy' looking mileage.
Any one ever heard of a problem like this before, or have any suggestions?
