Just Joined your site so Hi
bit of a problem though.
My m8 has just purchased an Astra G 1.7 CDTi
However on further inspection we appear to have an oily substance in the coolant system.
I have flushed the system through about 4 times and then recharged it.
He's done about 8 miles and hey presto it has returned.
On phoning the dealer we have been told this is normal fo the engine.
I must say i think he is talkin outta his rear end as this is totally rediculous to have oil in the water as normal.
Anyone else experienced this on their Vx Diesels or am i looking at doing some heart surgury for him?
