Vauxhall Astra H - 07 1.6 Oil light comes on on long runs - smokie
Just to wrap this up, the car was involved in a fairly minor shunt from a van, possibly uninsured, which resulted in it being written off. She was in the stationery car at the time but no harm done.
She now has a Suzuki, SX4 I think but I'm still in Portugal so am a bit remote from it all. I've been impressed thief she's managed to sort it all out without my presence!
