Clapton_Is_God 21 1 Cars Posted June 25, 2022 (edited) Hello All, My GTI 6 has been running poorly and I think I may have determined the problem but could do with some further help. At the same time as the poor running started the speedo stopped working. I've looked into it and I'm fairly sure the speedo drive (speed sensor?) on the gearbox has in some way failed. With it all disconnected, when I turn the drive cog manually it doesn't turn the cable in the dash. The car is fitted with a Citroën Xsara VTS gearbox. It's been a whole since I fitted it all and I can't remember what's what. Do I need a new speedo drive for the VTS box (not 205 box) and keep the black cog from 205? Is the speedo drive the same thing as a speed sensor? Also, where can I buy one? Update I've now removed it completely and when turned manually it does now spin the cable. However, the end of the piece with the cog on that goes into the sensor looks chewed. Is this right? Picture attached.

welshpug 1,657 Posted June 26, 2022 That white bit is the bottom of the square drive shaft that should be attached to the sensor. You need a dual vss, neither 205 nor xsara! Early 306 405 etc had them, still available new. They won't come with the drive pinion so you'll need to pull the remains of the square shaft out and fit it to the new part.
