Agreed Stephan.
After my initial response to the dealership, they dropped it and I never heard from them again.
However, 3 months later I started getting correspondence from the new owner, who was now looking at me to recover the costs of the engine rebuild. He got himself a fancy lawyer and that is where things got ugly.
His reasoning was that (and this is where things get tricky), to quote "in resetting the service counter/reminder, you deem that service to be unnecessary and are thereby extending the required service interval as set out by the manufacturer."
After much to and fro, I eventually received a summons to appear in court, in JHB.
Being self employed and not having assistance at the time, I could not afford the downtime, let alone flights and accommodation to pander to his needs.
I was forced to go the legal route to make the whole ugly mess go away.
