    Default need help

    ok few little problems will see if anyone on here can shed some light b4 i get shafted at vx

    1) right noticed this today driving down the motorway at 70 and whenever the front wheels went over a jolt the speedo would drop to 60 and then rise to 70 again almost straight away??? not a problem for normal driving but with the cruise on the car suddenly thinks its doing 60 and the speed is set at 70 so it accelerates then about 1 second later stops as the speed goes back to 70. really confused any ideas???


    2) had a new g/box flywheel and clutch done last year and ever since when the car is warmish it doesnt like going down the gears i mean i really ahve to shove it in and its not that the revs are too high it just doesnt wanna go in??? again any help appreciated??

    3) when we had all the bad weather my coolent system froze up after defrosting it my temp gauge hardly goes up. the car gets warm and the heaters work but instead of the gauge sayin 90 it hardly moves????


    the car in question is a 1.9cdti 120 80000 miles on the clock.


    also when should i get the timing chain changed??



    all help appreciated

    Unless you really know your stuff, sooner or later, a VX stealer will get you. Sad but true. They are no different from any other car manufacturer's franchised dealer network.

    This sounds like the speedometer sender unit that is fitted to the transmission. I have no idea where, exactly. But it will have an electrical connection and a block plug. It has either been fitted incorrectly or is faulty. If you've had the transmission replaced, that'll be when it most likely happened. Of course, it could be the speedometer head (the actual speed readout itself). I don't have direct experience of this fault.

    Maybe the 'box is tight or maybe you were supplied with a defective unit. Who did the work? Does it have the correct grade of manual transmission oil in it? And in sufficient quantity? Does the clutch 'drag' - that is, is it difficult to get the car in gear when it's stationary?

    Faulty temperature sender?

    It's a timing belt. It should have been changed by now. Check the service history. If it hasn't, plan on getting this done as soon as you possibly can. A timing belt failure will total your engine.
