MG TF computer not communicating
I have a Rover MG TF (54 plate). The key fob stopped working after I had left the roof open and it had got wet, so I arranged for a specialist locksmith with computer diagnostics to attend a re-programme a new fob, but after about 2 hours he gave up - it seems that the onboard computer was just not communicating with his diagnostic kit. The car battery had been flat but we had it charging up via jump leads for an hour or so and electrics all seemed to be working fine. Does anyone have any ideas? My local garage is stumped as is the specialist locksmith - is my car really now a write off as a result? It seems a shame as it is otherwise in good working order!
