Hello again Linda - Thank you for your reply...Ok there are two things here - If the cars computer is set up for "Long Life service intervals" -- then the service reminder function can only be reset ( or changed ) using plug in diagnostic equipment... so you would need a garage to do that for you --Obviously we don't know as yet how its set up - but from how you described the procedure, thats not quite right anyway...so I will give you the exact / correct procedure... try this exactly as follows. If its on Fixed Service Intervals - that will re set it---
So try that Linda - let me know how you go on.
Best Rgds - MIKE..
.... Meantime..............Please do click on the "OK/ Excellent ratings" for me as that's how Im credited for helping you - Thank you in advance for that...
