Thanking you, it's just the trustworthiness of the ECU I was thinking of, but as you say everything is fixable, I just wondered if it recorded changes to mileage on the ECU, my car had a mileage discrepancy in the first 3 months of its life 10 yrs ago as a demo car at the Audi dealer, they appear to have inadvertently added a zero to the mileage at 6 months this became apparent at its first dealer service. But once it's on the VMR it's on, I am just looking for proof it was not clocked,
Cheers
