If you mean the "check engine" light then what did the RAC say about that? Also, can you identify the flashing red light in your owner's handbook please Rick.

That's unlikely with a pre-engaged starter. They're designed so that motor doesn't receive an electrical supply until it is meshed with the engine. This, coupled with the warning lights, makes me suspicious that there's something else going on with the engine.

Yes, remove the battery and its box but leave the throttle body alone.

And just a tip on your original plans ...

If you have the common leakage the cause is flattened 'O' rings (CDU 3858). I'd strongly recommend retaining your original housing since it's likely to be higher quality than the replacements which also, it's been reported by members, have a cooler thermostat inside which isn't correct for our climate.
