I was looking up OBD II codes for my dead in the shop 2013 Panamera S hybrid (second Panamera that appears terminal in less than a year due to manufacturing problems. First broke in two due to defective aluminum frame welds).

I came across two references to using very cheap computer equipment to easily reprogram a car's odometer reading to any desired mileage. Apparently it's harder for a tuner to hack the Cayenne's or Panamera's engine control than an unscrupulous seller to hack the odometer.

Check out video on YouTube showing it being done in less than 30 seconds. Watch odometer in video be changed from 20,465 to 992 miles. Anyone know how to detect this kind of tampering?

Scary!

I would imagine telltale signs like inconsistent mileage on computerised service records, and mismatches between numerous counters like hours and revs stored in the ECU.
