Still not had chance to fit the new board.
The odd behaviour was first exhibited following a battery disconnect/reconnect.
Symptoms:
When connecting the cable to PC, the ESL board was detected with a port number but the error message "incorrect ECU version" was displayed.
When ignition was turned on fans and relays would activate as though green/black diagnostic plugs were connected.
They definitely weren't but the behaviour was different anyway, with fans on constant instead of cycling and different relays activated.
When trying to start the car it wouldn't turn over at all.
Just a click and the fans/relays running continuously.
The battery was draining. I suppose constant fans/relays etc would contribute to this but I feel that was allowed to continue for seconds rather than minutes.
I fitted a new battery and that drained too.
2 PCs, 2 ECUs, 2 batteries, same behaviour.
Andy at ESL responded promptly and pleasantly to my emails and, after a problem solving exchange, he suggested I send the board back for testing.
He soon reported that it had behaved normally for him!
However, he graciously offered to send a replacement anyway, which I must now find time to fit and report back to him and anyone reading this thread!
