The battery died and I have replaced it with a new one, but I now have warnings for gearbox fault, ABS fault, dsc fault, limiter not available etc. Along with warning lights. When I try to start the engine the information/radio screen goes blank but the dash remains in full operation. Any suggestions?

If all that happened, was you changed the battery, then we need to start with checking the cables and then clearly the codes.

Here is a guide that will help with this:

Once we confirm the battery is tight then we need to move onto the starter. This means we need to check the voltage at the starter and find out what is there. If you have 12 volts on both wires when cranking the engine, then the starter is the issue.

Please see the wiring diagram below and let us know what you find with this, and we can go from there.

Thanks
