Struggled to start this morning and showed message limited gears available, a few warning lights were on, mate plugged it in and got 2 faults relating to camshaft sensor, another lost communication with immobiliser and a speed sensor fault, he said forget the last 2, they all cleared and it started fine and has done since, although one warning light is still on its an amber p to the left of the park brake light? But can't find out what it relates to?

Hello mate

The Amber P means a problem with the electronic park brake,

If your in neutral and operate the park brake does it hold the car?

If so it may just be a erroneous error, but try checking your brake lights as a blown one can send the electrics doolally

If all good try taking the negative off the battery for 30 seconds, you will reset everything but it will probably clear the fault

Allthough if your struggling to start could be your battery is on the way out, get it checked, bad batteries cause all sorts of issues in these cars
