Hello Ive done a C1 on a 15 plate the other day,
Customer just rang saying the mileage is not changing,
If I remember correctly I've had this before and I had to step down the last 2 instances of the mileage is that correct?
So do I change fa4c fa4c to fa3b fa3b ?
Cheers

Post your file....
If you change the 17 words for the mileage (0x00-0x21), you have to correct the next 17 complement words to match (0x22-0x43).
Even mileage word = 00 00 Odd mileage word = FF FF

Ive tried programming it with both diagprog3 and smelecom and both machines did not program a working checksum so the speedo did not count any miles,
ive attached the original dump from this car its a 2015 Citroen C1 93c66
, would be much appreciated if someone could correct this file with a working checksum so it counts up miles correctly,
Original mileage : 18,000 Approx
Required Mileage: 10,000 Approx
Many Thanks
