Software and PC arrived today finally. Installed DiagBox 7.57 OK.
Ran diagnostics, faults all in top section. Mainly BSI engine speed sensor, then suspension (which I know about, and will ignore until engine starts).
The ESS connection block was the only harness I disconnected, my fault not disconnecting the battery beforehand.
However, I attach several photos in batches showing other errors.
The engine was running perfectly before work on cambelt etc, and all put back together properly; caveat, I don't know if I damaged the ESS connector or not.
I have owned the vehicle just 2 months, last 3 weeks it has been in hospital...
