Hi all, I need someone's help.

Some time ago my car went in for a new alternator and crank pulley as it had been suffering a stack of electrical niggles (iDrive screen fuzzy, PDC errors, battery dying after short runs etc)
Whilst in for the above, the mechanic removed 2 errors - Emissions Limit Reached AND Passenger occupancy sensor fail (think seat sensor is faulty but as its an '04 it can be bypassed).
Driving home from the garage the two alarms came back, BUT I also noticed that the mileage was now showing as 999,999 and the tamper light was on.
In NO WAY did he try and change the mileage - its around 140k and its backed up by service history and mileage.
BEFORE I GET FLAMED/ACCUSED - I AM NOT LOOKING TO WIND BACK MILES - I AM SIMPLY LOOKING TO PUT WHAT'S RIGHTFULLY DUE TO BE DISPLAYED ON THE ODOMETER AGAIN.
I have every intention of running it into the ground as it has been a money pit

The mechanic is not 100% sure how to restore this, and I would be keen to engage with anyone who has had this issue and could point me in how to restore the correct mileage.

I believe mileage is stored in three or four locations.

I also bought a cheap fault code reader recently and found some information that had errors in it (or appeared to be corrupted - maybe VIN) - could he have corrupted something when clearing the faults?

Is the VIN stored in a few locations and if they do not match up, can this cause the tamper light to illuminate? I read this in a post about an e39.

Thanks for reading and any help in advance.

Milage synchronizes with CAS. It does automatically to the highest value in case of a change of Kombi or CAS. There is a special instructions page, probably I read this in TIS.
Tamper dot is when VIN numbers between those two modules do not match.
If Hou have both, then maybe that's an issue with CAS. Due to electric glitches, or something. I am not specialist, and never had that issue. Although if I had I' d start with reading of CAS module. And CAS module stores VIN and FA. Someone with NCSexpert coding knowledge could probably find something not matching to the car... or maybe not... just a guess
Wish You luck!
