#1: 1999 Gti Speedo Problem Author: phreaker_uk, Location: South WestPosted: Fri Jun 24, 2011 7:42 am ---- I'm looking for some help with a problem just developed on my car.
Jumped in after a few days away, and I have no speedo.
When the key is first turned, the needle does it's usual jump up to its zero position, and it feels solidly attached, so I don't think a loose needle is the problem.
The mileage is not being counted either. With the door open I no longer get a warning flash/beep when moving.
Unsure of whether the speedo is linked to the ABS speed sensors on the wheels, but I have no ABS warning light on, and the ABS system is still working.
I've searched and found nothing helpful so far. At a bit of a loss as to what to do next, so any help would be appreciated.
To start with, anyone confirming 100% what feeds the speedo/odo readings would be useful, as I can't seem to find a definite answer to that either.
Thanks.

Speed sensor on the gearbox
OR
Broken wire at the multiplug behind the passenger front wheel.
Could also be a stripped speedo drive in the gearbox but pretty rare.
Pop the speed sensor of the gearbox & use a drill to spin it up to see if the speedo now works.

Correct.
Mechanical driven speed sensor on yours that sends an electronic signal to the instrument cluster.
Wiring multiplug behind passenger front wheel plastic arch liner is also worth a look, wires have been known to fail there.

I got an aftermarket one from eBay and it didnt fit at all, you're better off going to peugeot

What have I missed? Or is it always an awkward job to get to and you just have to work around it. I couldn't see a way of getting anything close to it.

#8: Re: 1999 Gti Speedo Problem Author: phreaker_uk, Location: South WestPosted: Fri Jul 08, 2011 10:43 am ---- UPDATE
It wasn't the speedo sender. Bugger.
#9: Re: 1999 Gti Speedo Problem Author: Linkpad, Location: WalesPosted: Fri Jul 08, 2011 2:06 pm ---- I gae up on mine just bought a radar speed detector instead for like 30 quid more accurate than the speedo anyway and they can't fail ure MOT for it. I reckon mines like ures a loose wire as it was working for a bit now cut off completely but i can't be arsed to trace the wires all the way back !!
#10: Re: 1999 Gti Speedo Problem Author: Edward, Location: In the garagePosted: Fri Jul 08, 2011 3:19 pm ---- Mine was a dodgy wire at the big connector. Speed sensor isn't difficult to change.
#11: Re: 1999 Gti Speedo Problem Author: phreaker_uk, Location: South WestPosted: Tue Jul 12, 2011 3:48 pm ---- Mine is not the same as the one in the pic there, unless that is a pic of something different. The sensor was a b*****d of a thing to get to as well, buried properly out the way.
Tried a confirmed working speedo head as well tonight, but still no joy.
I have a GPS detector giving me speed, but I'm more worried about the mileage not counting. Are there any issues with MOT or insurance if your mileage isn't updating?
Not sure what else it could be, could be a wire but the wires from the plug looked OK. Is it fused? I guess it would be a small current so linked in with other things, but don't seem to have lost anything else.
Apart from that it could be the mechanical drive in the gearbox I suppose, but I bet that is a hell of a thing to change as well.

Ive had a look at where the Speed sensor is and looks like its easier to get at from underneath Just seems like a loose connection or Speed sensor but im no expert i let u know if i fix mine when i next jack it up.
