Have you erased the codes from the ecu? Just a thought.

Hi,

More to the point, what are the current and any previous error codes, assume you or a garage have read them out ?

I did think that, but I assumed rightly or wrongly the op had got the codes read because of the new parts fitted. And perhaps didn't erase the codes after replacing the parts.

Disconnect the Battery for 5 mins and see if they come back when reconnected. If so, the fault is there still. Resetting the codes may only be temporary, but getting a specific code thereafter will help diagnose the actual problem.
