I know LPG tends to show up faults in cars that petrol is less fussy with and that's what i'm thinking as it's fine on Petrol.

I've changed all the coils and all the spark plugs. I've just swapped coil and pack from 8 (back left) to 5 (front left) with no change at all.

However we've also tried running injector from 8 onto 7 & vica versa which is saying the car, but.....Well what else can cause misfires???

Vagcom codes :

P0300 Random/multiple
P0308 Cyl 8

Any ideas ???

Hi Lee well it’s going to be fuel, spark or compression. Not sure what engine you have but for me with a similar issue turned out to be a vacuum leak caused by defective the oil separator valve, but that was on a BSM Engine. You may want to check all your vacuum lines and breather as another possibility. Cheers
