When I was back in the uk, I had a problem with the clocks on my 2.0Di. Off I went to Megavaux to pick up a replacement and fitted it. However, problem now is that the mileage reads that of the donor car i.e. 54k instead of 138k.
I thought that the mileage would be held in the ECU, but it seems not. How do I re-programme it back to the correct mileage?
