Car going fine , parked it up , three days later start it and all this is coming up ,
The battery is new replaced 6 months ago and has never died never needed a jump start
I know it’s like a needle in a haystack but any ideas and what code reader can I buy with out having to remortgage the house that will give me a in-depth idea of the problem
