300 TDi speedo

Hi, Landy Lady in need of a bit of help. I have a 1998 Discovery 1 300 TDi auto, the speedo has started to bounce up and down, can anyone please help.

If you mean the speedo needle then check the vehicle speed sensor attached to the transfer box either the electrical connection or the sensor its self could be faulty.

Had that problem on a 96 Tdi recently .
The transducer (think its the same part for auto and manual ) on the gearbox was worn . Changed it - all fine again .
Easy enough to change .

Yes I had the same problem, had to change the speedo head. Dead easy but £130 ouch.

try the connector lead( black plastic cover on a terminal with about 2mm diameter wire attached)
on the alternator,
this sorted mine as it was loose.

Just tesssssssssssting I know

yeh,
does me good
really, concentration not what it was.

Thanks all, have taken off the transducer and cleaned the terminals but no joy yet. Next step is to get new one and try that.
Again thanks to all for help, will let you.
A very grateful Landy lady.

i heard that if your alternator is going that it can cause the speedo needle to jump eraticaly. could mean somethings wrong with your alternator BUT i would double check that with some one in here with more experience before you start messing with it. I could be wrong so do double check this. hope you get it fixed

As the last post was nearly five years ago and he has no additional posts in the forum in that time, don't hold your breath waiting for an answer.

I'd agree right enough. Cheers
