Speedo Issue

[Pipeandacrepe]

I suspect this is a common fault thats been done a thousand times, but..

My speedo has taken to not working for the first 5-10 miles of any journey. Ive read about the packing up altogether, but not this. What would this typically indicate? Other than it's a bit fked. Cheers.

Shamless bump back to the top...

Mine behaved very oddly before packing up fully, including your symptoms. Some days it'd work and others not, and some days it;s work for just as long as it felt necessary.
Ended up having the sensor replaced at the diff end.

[Pipeandacrepe]

That's what my Googling suggested, where did you get it done?

Cheers

I got it done at APM in Liphook. Any TVR place should be able to do it no bother.

Mine did this when I first had the car. The sensor on top of the diff had to be replaced

[Pipeandacrepe]

Is that the same thing as a transducer? Is it a DIY thing or a garage job?

Fixed mine. DIY job. Need a good light and long fingers! 11-13 thou clearance.

Thanks all. Might try cleaning it up, see what happens, though the part is cheap considering.

Mine did this today. I waited for it to click over to 40K but it stopped on 39999. The trip meter stopped too. It started working again on the way home.

They all do that sir.

Is it fair to say Chimaera indicated mileages are almost always cobblers?

From my own experience, no, but not deadly accurate. In my 6000 miles of ownership the speedo and odometer was intermittentlyfaulty when I got the car. By the time it was fixed I had probably done 250 miles. Then it stuck at 70,000, but only for about 70 miles, freeing tself the next morning. Otherwise it has worked throughout.

My Odometer and Trip counter stopped today, just stopped on 49399. MPH is ok.

Do I need to prey to the TVR god to make it work? Or is it a job out and find someone to fix it?

Leave it alone and it will eventually fix itself. In the mean time enjoy those "free" miles on your limited mileage Classic policy (I didn't just say that!!)

Sorry to hijack this, but I have the digital type odometer and have no read out at all, I believe there is a battery in it that may have died, Is it possible to replace it myself, or is it a specialist job to reset / programme the mileage into it?. If so where is the favoured place to send it?.
Many thanks

My odometer hasn't worked in getting on for three years ... been looking at the Smiths "Flight" range of gauges which look rather nice but I'd need to get a new dash cut as they're 52mm gauges rather than the 60mm of my ETB gauges and adapter rings are impossible to find over here.

What I'd like to do is get myself a new speedo fitted (the Smiths "Flight" one looks nice IMO) and run the car for maybe six months or a year between MOTs so that I can get a reasonable idea of what mileage I do in a year, I know what it was on when the odometer failed (as it had just been for an MOT) and then just use a signal generator to drive the speedo and rack up the appropriate (ish) mileage before refitting.

LOL - sounds the same as mine...

Speedycables I believe do them and I think that ETB instruments can also do them - I'm looking at replacing mine though as mine also "sticks" and needs a tapping to get going in the morning so for what it will cost to repair I can pretty much get a new speedo.

Well after going for a blast again on the A38 and resetting the trip counter a few times, it started to work again. Seems to have trouble with rolling over 9's.

I have a problem with my speedo too. It keeps racing to 100mph, no matter what I do when I plant my foot and change gear the noise just makes me do it....
