Hello,
My car is out of warranty (Astra) and I want to do the servicing myself but the main dealer used to set it to show InSP on the display every 50 weeks. Is there anything I can do to reset that? I felt I was being ripped off with servicing as all they did was an oil/filter change. I'm not interested in devices for tampering with mileage etc, maybe something that will show up faults.
Thanks.
