Many people get a diagnostic for an issue, replace the part but never clear the code.

I was buying a car for my dad, querying the BSI log of faults and said to the seller "I notice it had a temperature sensor fault at xxxx miles. Was it replaced?"

He was amazed I could find this stuff out, and showed us the receipt for the replacement! And the date of the receipt tied in nicely with the mileage.

"Well if you did you've managed to do 4000 miles since you hoovered it last week" I replied
