Without looking at it it's very difficult to say sadly.

Hopefully it's sorted for you.

What I meant was that my car failed to start. The ECU is replaced and now the car works.

So, was there a fault with my ECU (which I expect to be unlikely) or is there a hidden intermittent fault which is going to strike again?

If so, what do I ask my dealer to check for?

Thanks

I had something similar, and it was the software on the ECU rather than the ECU itself. Mr Shark Performance solved that mystery for me
