Speedo is Sh17e

[NickD]

Just driven along a section of dual carriageway that is littered with cameras each way.

I am motoring nicely along at what I thought was a law abiding speed of approx. 50mph (50mph limit). However, just as I had gone past a camera but was still in the area where there are lines on the road I thought I seemed to be travelling a bit quicker than everyone else.

So I changed the display to show the digital readout and it says 59mph (needle showing about 47).

Gutted. Not sure how many cameras I've gone through and wouldn't have seen the flashes as I wasn't looking out for them and it was too sunny.

Am not happy at all - guess I just sit and wait for 14 days.

I have the same problem. Only happens when driving at a constant speed for longer than approx. 15 min. The analogue shows a speed about 10mph less than the digital.

[NickD]

Went out again yesterday and both readings correlated for approx. 20 mins. However, then I got a Code A (although no code the day before) on the display and the needle stuck at 10mph for the remainder of the journey.

Presumably this is something that is easily fixed? I bought the car at a dealership in the Derby area but do not want to travel back up there for warranty work. Any recommendations of places in the London area?

Cheers.

Seeing as you are out Docklands area, you could see Castle at Stansted. Not that close, but the dealers is in the town and you can walk to the train station to get back to London again - I've used them for simple stuff on my Chimaera before and they are OK.

But as PH confirms - be careful with any dealers and make sure that you talk to them and get a decent relationship first....

Cheers,

I must admit - I've had some speedo issues - although a little more bizzare than yours.

I've had my car from new, and just after i got it back from the 1,000 run-in service. I took it up to "an excessive speed" (quiet road of course ) After a little while the needle began to jump around erratically (even when stationary - also noticed the mileometer creeping up when stationary at traffic lights). The digital readout was also erratic. I began getting various Diagnostic codes (K,L, B, C ...).

I took it to the Dealer to get it fixed, and the car had to go back to the factory for a few days to get a new console. It occasionally plays up now but is generally OK.

Here's a definition for your Diagnostic code :

Tuscan Dashboard Diagnosic Codes



A - Speedo not activating zero switch/switch failed/open circuit

I'm also interested in the current state of speedo fixes applied by the factory - since new, my Sept 01 RR progressively gains on the analog dial over mph resulting in the needle sitting high on the dial when the car is stationary. The digital readout is fine (within 1-2% of GPS). The car is going in for its 12 month service at Henley next week, and they tell me its a pod-out/return to factory fix - just interested if anybody else has had a fix for this recently and if it did the trick?

[johnwilk]

My pod was whipped out and fixed while I was at the Factory. A very nice lady took it apart and showed me a small nylon worm gear which had destroyed itself. Since that day my digital and analogue speed reading has been exactly the same and as far as I can tell, vey accurate. Prior to the fix I regularly recorded 200mph and occasionally 0 mph at the same speed. However, my digital speed output remained constant. If your digital output is not showing correctly, then the sensor on the diff may need resetting - the old style sensor was very prone to dirt and dust, but the new one is more stable (I think your car has the new one, or would have been upgraded - might be worth checking though)
Hope this helps

Yep, had this, got it fixed. The sender unit was replaced at first - this fixed a waving speedo when the needle got past 12 o'clock. You can tell this was a sender problem as the digital and the needle matched.

Then a problem remained that past 12 o'clock the needle would add mph. A trip to the factory for a few days to turn around the pod, and all is now well.

I had the pod removed and sent back to the factory after a few months of ownership, then the speedo sensor was changed & setup correctly which stopped the needle wandering around the dial and todate have had no further problems with that.However in the really hot weather I still sometimes get a diagnostics code B speedo sensor not releasing zero switch or broken and the analogue dial reads <0 MPH and if you start off and drive like this the analogue speedo will under read by about 10MPH while the digital reads correctly.However if you switch off the ignition and back on again the needle jumps back up to 0 and everything is OK.

had my pod removed (ooer) last week as the speedo was playing silly bu66ers. got it back yesterday and not only that, but the mileometer shoots up even when stationary! (it did read 100 miles for an 8 mile journey!). it breaks my heart to see my car visibly depreciating...

Hmmm - interesting - did your pod go back to the factory? - I only ask as I've just had the Tuscan 12mnth serviced at a nearby dealer (now that the dealer who sold it to me isn't a dealer any more) and they told me that there was no point taking the pod out this week as the factory was on holiday. (They also said the speedo behaved fine on the road test, but since it only starts to lose zero past 1 mph, thats fair enough). Interestingly, they pointed out a couple of things my vending dealer didn't - like what appeared to be a bit of cardboard glassed into the outside of the floor behind the drivers seat - all part of the factory's dedication to saving weight I suppose. Oh, and the other thing is the local dealer also sold me a TVR Spirit extended warranty for the Tuscan (for what its worth) - which surprised me as I thought nobody was flogging extended cover for Tuscans apart from the factory...

I picked up my second hand Tuscan last week, just after it had returned from the factory to have the speedo fixed. The analogue went up to 50 mph then just died. It's fine now though. On a similar subject, does anyone have issues with fuel levels? Mine can vary from 0 to 15 litres whilst sat in stationary traffic. Also is there a trick to prizing off the petrol cap if I have over tightened it? The vacuum from the emptying tank makes it almost impossible, especially as I can only get a thumb and two fingers around the cap. If not does anyone know where I can regular skin grafts?

One of the nice alloy fuel caps from Leven sorts the problem of trying to remove the standard one.

Mine's the same - it's really annoying, when the fuel gets low the reading becomes totally unreliable - which is of course when you want the reading to be accurate so you can guage whether to start panicking.

But then again I find all of the instrumentation pretty useless.

[Suggs]

I had a very unreliable speedo for about 18 months, it was eventually given a new sensor and its been fine ever since.

On the fuel level question, my guage does vary a bit depending on incline and accleration/braking but the worst thing is that recently when the level drops to about 12 litres or below the engine loses power every time I go round a corner. My dealer says that they all do that and I shouldn't run the tank so low. Anyone else get this problem?

[Nick Elliott]

I usually run down to about 5 litres and have no problem with fuel starvation, although when cornering hard even with the tank half full on the guage does swing around between 3/4 and empty.

[andyvdg]

I get nervous when the guage drops below 10, mainly as during hard cornering, the reading can drop by as much as 10 litres!

I've driven it down to 5 no probs (no loss of power or anything). Mind you I was going very slowly towards the nearest petrol station!

Cheers,

Andy.

Speedo turns to fuel?
Well so be it my gripe is fuel.
Bought second hand early Tuscan with 2000 on clock and on first fill up the world stinks of fuel.
I pulled back the trim in the boot to reveal the top of the tank and low and behold the breather pipe isn't connected. worse. it doesn't even fit the tank. I bodged it with some 8mm pipe and a vw polo filter to get to the dealer safely. Its now fixwd but WHAT THE FFFFF! If I had been a gimp and not sussed it I could a bin fried by the time I got there. i guess owner no 1 never filled the tank(or drove it much in the 2 years he had it.

Morale?

Don't trust them. Love em but don't trust em. Just like women really.

If the speedometers are not very accurate, how fast do you reckon this Tuscan S is really travelling then:



I found it at

http://come.to/need4speed

which claims it is 210mph
