I get lots of little errors when the temp drops below 0c, ABS, Gearbox, DTC, TPS and some on. just let it tick over for 10 min in the morning then restart and most of the faults have gone.

Probably not the same fault, just a thought.

Do the alternators in our cars have built-in and replaceable regulators? I can't see replacing the entire alternator if it's a component that is causing the problem.
