Thanks Graham! once again, fascinating stuff. So there is hope the true mileage of my vehicle can be recovered, we just need to find out its secret hiding place. After that, we need to find out the source of the communication issue between the wheel rotation and the ODO.

 

Reviving this old thread, did anyone ever find out where the true total mileage is stored?

 

Also interested. I've always been suspicious of the miracle of so many low mileage X150's. Remarkable number of elderly gentlemen who only drove them every few weeks to the country club and back.
