Ouch, at least it was sorted.
Thanks for getting back with the solution Mark.
I was once asked if i could reset an the oil service interval on one of these.
I said if it's a 5min job for me, the price would be a test drive in it

He said, based on what he knows i used to do, he would rather pay me £40 and have me closely supervised when i had the key to the beast.
He never contacted me again, i was gutted

All i did was try and help
