aparantly their is a speedo drive in gearbox that has been changed

Expert:  Mike replied 3 years ago.
Hello again - Thank you for your reply...

Yes indeed there is - I just needed to be sure..

That "drive" is driven by the cogs in the gearbox - that in turn, operates a VSS...speed sensor - which in turn , operates the speedo ( clock )..

Its an easy task for a garage - with suitable diagnostic equipment - to plug on and see if a signal is being produced from the VSS... and if it is - then the problem is , normally with the clock...cluster.. - If you are positive the clock / cluster is ok, then if you so have a signal from the VSS, that proves that is ok and the "drive" is ok...and hence the problem is with wiring / circuit , in between .

If there is no signal - then its a faulty VSS - certainly so if you havn't changed that and that is the common suspect.

If there is no signal - and the VSS is new or proven to be ok - then you have to check that the drive that has been fitted in the gearbox - is actually working - ie, being driven, by the gearbox.

So working through the above, you will get to the bottom of this.

I Sincerely XXXXX XXXXX have helped you - but do ask me if you need anything more..


Kind Rgds, MIKE
