Hi there I let my battery go totally dead. Tried charging it in the car but no good. Took it out and replaced it and all the engine lights are on intermittently. Sometimes, I start the car and all is fine, and then after 1 minute all the engine lights come on - including tyre sensors, ABS, EPS. But mostly I start the car and the lights are all just on. I've got a cheap code reader and it shows loads of codes. Any tips of what to look for would be gratefully received and if I can't fix it is it worth trying a new ECU? Thanks Andy
