Thanks for the reply.

I used a battery conditioner/trickle charger on the old battery last weekend and all week the car has been fine.

Yesterday I had a new battery fitted and registered to the car by a different specialist just to be on the safe side.

HOWEVER. In the last 30 minutes all the faults suddenly came back.

Namely -

All the fault codes shown above.
The automatic transmission warning appears occasionally.
It's losing power and the speedo dies occasionally.

The new specialist said that he'd scanned the car for error codes when he registered the new battery and the only one(s) that came back were "speed sensor related". At the time I/we were convinced the faults were the result of a bad battery so he didn't pursue the speed sensor faults/codes.

Would a fault speed sensor cause all the symptoms I'm experiencing?
