Just driven back from a friend's and the speedometer has given up the ghost. All other gauges are working fine, but speedo is stuck on 0. Consequently the steering has gone heavy, and then the HICAS light came on after I'd driven a mile or so. Now I know I've read something about this before but having done a quick search can't find the relevant thread.

 

Is this going to be down to the speed sensor, or is there something else that might have bought it? And if so where is it, how much is a new one, and how difficult is it to replace? I've got a Series II '93 Manual TT. Strewth, these cars, sometimes, and only sometimes, it does feel like one little thing after another. Ho-hum. ;)

 

Any help gratefully received.

 

 

Thanks,

Bart

Good luck bud, i've been told its either my speed sensor, which is apparently working, my convertor box, or my speedo itself! Liitle problems are a bleesing, big problems are a bitch!

Yeah, I can't complain too much -- the car's pretty reliable, it's just it always seems to do something like this when there's a billion other things going on. C'est la vie. If you're gonna own a zed you have to accept that this kind of stuff is going to happen. I just found a thread about this and might just try resoldering all my speedo connections... although I'm not yet sure if the odometers stopped working or not, so will have to take the car out for a run tomorrow to check that.

Cheers,

Bart

The speedo itself being the cuase of the problem is pretty rare. Its much more likely to be speed sensor, or mph/kph speed convertor.

 

If you have a mph/kph convertor, remove that first as its cheap and easy to do. Then test.

 

If not, then its likely to be speed sensor.

Thanks mate... it's working again this morning, but something's definitely dodgy. If it happens again, which I'm sure it will I'll reset the trip mileage -- if that's not working I'll know for sure it's not just the speedo. Thanks for the link. I'll follow the advice there... in fact I might just bung my multimeter in the car just in case I'm away somewhere when it happens.

Cheers,

Bart
