Do I need repair
Please can I have some advice. I put petrol in my mini one 2010 yesterday and then the emissions warning light came on. I had diagnostics today and error code is for faulty camshaft sensor. Warning light has been turned off and car booked in for new sensor next week. It's running perfectly so if the warning light doesn't come back on should I still get new sensor? It will be quite pricey so any good advice would be much appreciated.
