My Griff is just on 40k miles, but the mileometer has stopped altogether at 39,999, and the trip counter is not running either. I am confident that it has not been clocked, but I am a little concerned. I have done about 50 miles without it working now. Does this sound familiar to anyone?

ours stopped at 19999 and 29999 and a few days later started back up again.

no idea why!

Its true, they do all have that endearing feature! Mines stopped 4 times now at different 1k rollovers, and started again sometimes on its own and someimes at the next service. The car has probably clocked itself by about 2k over the 24k recorded.

Very common. Mine stopped at 29,999 and didn't start back up on its own accord after about 100 miles ish.

Its gone back to Kings for a variety of bits and pieces, including this.

The bad news is that TVR don't stock Griff speedos anymore (which I found a bit alarming given how recent it is since they stopped building them). Mine has been taken out and sent to TVR, who will send it for repair then return it. For some reason they won't let the dealer send it to the repairer direct. Been without the car for 3 weeks so far. At least I have a Cerb Speed 6 as a loan car whilst it is sorted.

I am rather worried about TVR's (lack of) stocks of Griff parts. Some dealers still have new Griff 100's for sale - yet TVR don't hold spares for them. I thought car manufacturers were required to make spares available for 7 years after the demise of a model?

I think Speedy Cables (?) are the people who do the repairs on the speedos - someone here might be able to confirm.

It must happen with X9,999 miles on the clock because that's when the greatest force is needed to turn all the wheels over. Clearly the force from the cable or whatever can't overcome the load - like when an battery clock stops with the second hand at 9pm.

Only TVR could make a speedo system that can't do this simple task!

Perhaps it needs a little extra help to overcome the cogs in the mechanism, how about a quick 150 mph blast! Oh and as for Griffith speedo's why not fit a Chimaera one? They still make those (oops soory) so they must have some speedo's!

How can a dealer ever morally state 'genuine mileage'????

My speedo stopped turning at 12,337 miles and hasn't worked since. Neither has the trip.I was told it will have to go to a repair shop. I hope it starts again pon its own soon as it sounds a real pain to remove dash and speedo, get repaired (180 pds!) and reinstall.
Suppose I have done about 50 miles since at varying speeds, speedo works fine but no change to the mileometer.

Just had a stoppage at 19,999. My '94 Griff is on it's third speedo, was worried I might have to fork out for a fourth. A sound thrashing round East Sussex on Sunday managed to put things right again...

Julian,
Any ideas how exactly you got it working again. I have done 30-50 miles since mine froze at 12,337 miles. I don't fancy having to get it repaired but if I do can you tell me who repaired or replaced it for you?
I am in West Sussex so hopefully local to me?
Chris

chrish,

I've only had the car 6 weeks, the last owner forked out for one speedo, the other two were under warranty. As for getting it working again, I drove it pretty hard for an hour or so, and it sorted itself out - I was almost dissapointed!

Sorry, probably not much use to you.

I am trying to figure out why driving it hard should make any difference to its workings. I have driven 30-50 miles at various speeds, without wishing to say any more and it didn't make any difference at all.

yours is NOT the typical 999 rollover failure - which seems to occur because there's too many digits to rotate and not enough energy to do it (!) - it sounds like something is actually broken rather than the normal TVR 'just about do the job if you're lucky' design fault. Don't hold your breath waiting for it to fix itself!

I guessed that but somehow hoped it was going to fix iteslf after all these emails on the subject.
It seemed to happen after the winter layover. The Speedo works fine, doesn't stick or lag.

Drop out the dash - take out speedo - clobber it a few times - replace. Worked regularly on my old S3 which had a habit of jamming.

It's the mechanical mechanism for turning the numbers over that's at fault. It's electrically driven by the amplified pulses from a sensor in the transmission, so driving hard, fast or long won't help !

It is not just TVR this happens to, I have had it happen on a Ford and a Hillman (some years ago).
