1999 XK8 runs perfectly, no issues. The only fault is non function of drivers seat heater. Ran a scan with the icarsoft and got a bunch of fault codes - U1135, U2012, B1202, U1260, U1261. They may be very old as the car has no issues but I cannot erase any of them. Is the icarsoft incapable of removing the codes? How do I remove them? Also got several messages of mirrors out of range, seats out of range. Cannot remove any of them.

 

The next generation of ixarsoft scanners (icarsoft LR v 1.0 / v 2.0) can remove more codes.

But if the car is running well, count your blessings and keep buying gasoline
