wobbly speedo.

[kagey]

any ideas why my speedo goes back to zero when i go over 100 mph?
has this happened to anybody else?
if so how can i get it fixed? is a quick visit to my local dealer or back to blackpool

Mine goes to 200! I think that it is a case of a pod return to sunny Blackpool.

sounds like its losing signal from sensor on diff could need adjusting

This is a well known one - after three attempts, dealer fixed without need for new pod. Mostly it is caused by the pickup being incorrectly positioned, dealer should be able to help.

Mine hit 200+ and is currently in Blackpool for a fix.
It is an issue that requires the pod to be returned.

I too think that it could be the pod. Check to see if the digital display is accurate compared to the needle. My digital is accurate but the analogue goes crazy.

It may be that sending yer pod to Blackpool fixes this problem, but mine WAS fixed in minutes at the dealer - twice! (first fix lasted 500 mls, second fix has lasted 12000 mls, and is still fine). Symptoms were:between 70mph and 100+ mph (on track, of course!)needle would behave like an eratic windscreen wiper, particularly if accelerating hard. Much above 100, it gave up altogether, and rested at zero, with an occasional twitch. Digital readout remained good throughout. (which confused me). Dealer adjusted the gap, between pickup and a 'castellated' ring which I think is on the diff somewhere, where it counts the passing of 'teeth'. plusminus a few thou is all yer allowed. This would be quicker than sending pod away, of course... there may be another problem, it's a TVR after all!

my digital readout goes back to zero as well as the analogue and then bounces all over the place. like i said it only happens over 100mph. wierd!
anyway i'm gonna let my local dealer have a look to see if he can sort it.
cheers.
