Thread: Gearbox fault

Hi Scrouge,
yes I would not think it would cause a fault. And I did not notice the fault when I drove the P38 to the window tint people, only when I went to drive it home, and after I connected the center brake light the fault was still there until I got to the corner then I turned the car off and restarted it and the fault was gone. Then I drove it to my mates workshop and checked for codes and there was none there. So all we could put it down to is P38 gremlins, and leave it at that. If it reoccurs I will look into it further.
Thanks for your help, Alan

As there are no fault codes present, is it possible they left the radio or hedlights or something else on that may have drained the battery?
So when you got it back it had a low battery, which triggered the fault to appear.
With a bit of driving the battery has had time to recharge and the fault went away.

From what I've read, more often then not, it's a low voltage issue, can be caused by corrosion in the battery cables or an earth point that needs cleaning.
If it's gone away, you might be in luck with no actual problem, but if it comes back I would start investigating electrical causes.
There's a great troubleshooting write up here that takes about 5 mins to do.
