The other day I started getting the little engine symbol lit up in orange. Today I am getting the message "Engine System Service Required". To top it off I am heading for Devon on Friday night.

Can anyone recommend someone in the York area who can read the codes and fix the problem?
Only noticeable problems I have seen is that for a few months now the engine power delivery has been hesitant at times. Although it did improve on premium fuel. Could this be a throttle problem? Any advice would be greatly appreciated. Need to sort it fast. I imagine it would be a bad idea to risk a 300 mile journey?
