The speedo reading on the new V5 STi is already starting to get on my nerves, seems to read the correct speed but every so often twitches up 10mph or so, stays there and then settles back to normal.

Any ideas?

Either a defective speedo sensor on the gear box, or a defective speedo itself.

Is the sensor on the gearboc difficult to get to?

If its speedo itself, any ideas what it could be?

1. No, so long as you have ramps.

2. Nothing repairable.

You could try a new set of clocks, or a new speedo, but avoid dealers, their prices are stupid, they have banged them up by over 150% in the last two years

the speed sensor is on the top of the gearbox, so its a TMIC off job not ramps IMO

Reading through history of the car, its went 2 or 3 times in its lifetime so I'm going with the speed sensor... I've not got ramps, so is the easiest for me going to be removing TMIC and going in through the engine bay?

Try TMIC first. I am only 5'8" so prefer to reach up rather than down.

have you ever had the cluster out? I did, it began after that. Mine is a P reg so not electronic

Best way to fix was do undo the cable from the gearbox, so you can get the slack in order to do the end that mounts to the rear of the cluster properly, then fit cluster to dash, then put cable back in to gearbox. Also i think there is a little metal component that can wear - where said cable mounts to the gearbox

Its a version 5 mate, so electronic... will just take a look at the sensor, clean it up abit. If all else fails get a new one

No harm to give a "technical" tap on the sensor.
