a lot of wiring and leads etc were disconnected when the clutch was done ..you're best going over it all, checking connections at battery ..earths, etc
if no joy, you are then plugging in a scanner.
i suggest use forscan
NOTE: and use forscan to get correct fault codes with proper explanation of them - a generic fault code reader may be somewhat misleading
Here on this site - They recommend "Forscan" which is
FREE software that you download to a laptop..you buy the interface cable
You can join the forscan forum ..again free, to get the software directly and more answers.
