hmmm ... just tried pulling F26 on mine, then turning on ignition and sidelights - number plate light not lit, but gear selector indicator is. So it's unlikely to be that, as the number plate light works fine when F26 is replaced.

Adjusting the instrument panel illumination dimmer made the LEDs glow less brightly - but not go out completely. Are the rest of the dashboard and climate control lights working? (I assume so ....)

Every other light works it's just the gear selector that goes out as soon as you turn on the headlights, turn them of again and the selector light come's on :-/

hmm ... odd ... I'll pore over the cryptic diagram more closely tomorrow and try to decipher a bit more !!!

funny that my old car's got the exact same problem though ...

I'll get a look at this when you're up the road at the weekend Jim. I've had some further thoughts on it and there's a few things i'd like to check out with the "Fluke".

I thought a word like 'Fluke' woul be one of the banned ones.....

Jim, I'll live with mine until Kev or someone else had fathomed out the problem, I hate trying to find electrical faults  

Sounds2k, I know my number plate lights are working as the car was just mot'd and had the fault then. I've also checked every fuse was the right size, present and correct. I've always done this when I get a new car, goes back to finding a bolt in place of a glass fuse many years ago  

Cheers Jim

[Markie]

dunno about this one - all fine on mine......btw i have a spare selector here known to work so Kev/ Jim if you want to check it out to see if it makes a difference give me a yell......

I had a play with mine in the dark tonight (maybe should rephrase that  ) Anyway, I noticed that if I selected any gear before putting the lights on, the led indicator stayed lit. As soon as I changed into another position on the selector or tried to dim the dash lights, the led goes out and stays out. Weirder by the minute  

Cheers Jim

sounds more and more like a problem with the chip that drives the LEDs - whether it's on the board with the LEDs on or part of the gearbox ECU though is another matter. Could well just be a dry joint or loose connection somewhere, but good luck finding it

I'm back down south at the mo, and back in Glasgow at the weekend so hopefully Kev can sort it out.
I'II keep you posted.

Hi Jim, did Kev have any joy with your selector lights? I've noticed with mine that if I put the light switch on quickly, the selector goes out, turn it slowly and it stays in!!! Still goes out after you select a different gear tho....  

Cheers Jim

[sounds2k]

has there been any progress on this? AFAIK my old one still has this same issue, will be down there at xmas though so can have a look whilst I'm there ...

[sounds2k]

an update on this at last ... yes it's the same problem - selection illuminated fine until side or headlights switched on, then only the backlight is on. Switch off lights, selected gear lights up again.

Swapped the display module with that from my 3.0 (a known good part) and the fault followed the display module, so I left them swapped. Hmmm ... now I just need to replace mine  

There is some logic circuitry on the back of the circuit board, I'm guessing some of that might be shot ...

I have one that does the same thing. The one that's in the car now varies which light it'll light up, sometimes its D other times D won't light but 3/2/1 will.   :-?

don't rule out selector switch if its lighting up wrong leds...
