It's only done 40k miles so the engine should hopefully be fine. I'm wondering if the garage i've gone to to have it filled up put the best oil in (i know they said they put in synthetic oil but not sure of anything else..? If they didn't put in the best oil then maybe this would make it go sooner? .. anyways.. I had my service less than 6 months ago and nothing showed up on the diagnostics test.
Im about to buy some oil for when it happens again. Halfords are showing three brands for my car that they sell, which is the best?
Halfords 5W30 Fully Synthetic VW/Audi Oil
Castrol Edge 5W30 Oil
Mobil 1 ESP 5W/30 Oil
