[Mk2] [Turbo] Speedo doesn't work and engine management light comes on

Post by Mr Two »

Hi all
Sometimes my speedo doesn't work for a short while...then the engine management light comes on....then after 10-15 mins or so the speedo kicks in and soon after the management light goes off :shock:
Any suggestions please?

Cheers

Sounds like your speedo sender unit mate.

Its a bloody nightmare to take out too :lol: .

I would imagine you have error code 42?

Maybe speed sender in the gearbox. The sender unit wheel is made of plastic and comes off / shatters inside the gearbox (won't really do damage inside, just be ground to dust :lol: ). Without the speed signal engine light will come on above 40mph IIRC.
however yours work occasionally, so perhaps a wiring fault ?

Yes - my speedo is just stubborn "occasionally" to kick - in but once it does its fine...so maybe the wiring?
