looking at the codes, i would say a large number of them are due to low voltage either from a poor battery or the car not keeping the battery topped up (charge rate or very short trips etc)

also the heater flaps may have the linkage issue that needs sorted, and if this is the case, there will be a clicking sound when you first switch the ignition on when you get into the car, a click every 5-10 seconds for about a minute or so

and Television's profile doesnt say he is banned on my screen!
