Limp Home Mode
« on: 05 February 2012, 17:20:58 »

Had a problem earlier in the week that I thought was gearbox related but I've since found out the car had clearly gone into limp home mode. http://www.omegaowners.com/forum/index.php?topic=98907.0
Problem hasn't reoccurred since Thursday but I'm now wondering if the following has caused it.
Wife advised that the TC indicator on the dash flashed on and then the car entered limp home mode. On further inspection I've noticed that when reverse gear is selected the rear fog light indicator dimmly lights up on the dash. On checking the reverse lights, the offside one is fine but the near side reverse light is only half lit.
My question is could this electrical issue of caused the car to enter limp home mode taking into account the first action at home is to put the car into reverse to get the car off the drive?
Does anyone have any idea what would cause the electrical problem with the reverse lights and would a change of bulb rectify the outage to the rear fog light indicator or is this likely to be a job for an auto electrician?

I suspect the 2 are unrelated to be honest.

The supply to the reverse light comes from the multi-function switch on the side of the transmission.  It is possible that a short of some description could drag a too-high current out of some of the transmission components, prompting a "limp-home".

If, for example, there is a poor earth, or the wiring has got trapped in the boot-lid, then you could be trying to earth through the fog-light supply, hence partially-lighting the indicator.

If it happens again, pop out BOTH bulbs on the affected side of the car.

Was trying to tell you that over the weekend, but couldn't get through.

Agreed - likely to be a bad earth mate  :y
