Long story short, broke down and had to have new cambelt/timing belt changed, plus head gasket sorted. then she was misfiring changed whatever part vauxhall told them to change still misfiring. So garage took it to local vauxhall dealer. which they finally sorted 2 weeks ago, but EMU was still flashing took a week for vauxhall to check wiring and say EMU needs replacing.
And on hols next week with a naff Loan car, which runs out of tax on tuesday so all in all not pleased.
She's a petrol engine if this helps.
thanks
