Hi mates,
my car speeso is down since years and years, I have tried everything to fix it but in vain, last time I tried new sensor on the gearbox top but again no joy,
I removed it and inserted my finger in the hole to check the control screw inside I found it free namely can be turned by hand so this means it is not proberly engaged.
what do you think the problem with the screw, it should be engaged right?
is shouldn't be free like that, any body know the mechanism of this screw drive?
I hope that somebody can give correct answer to this question as it is a very common problem with this particular model?
thanks in advance.

Have you tried removing the inner cable? Check the end nearest the gear box is not damaged. Many years ago I had a car which had the drive to the sensor inside the gearbox faulty meaning removal of the gearbox to repair. Hope this is not your case. Assuming you are in the UK, you are aware that to use the car on public roads you must have a working speedo? Would not be surprised if other countries had the same but I can name some where working speedo's are the exception, rather than the rule, e.g. parts of West Africa!
The sensor has what is known as a Hall Effect sensor, if it is not positioned correctly you will get odd results from nothing to intermittent. Haynes manuals may offer the solution.
