  1. I would definitely get the car serviced as soon as possible.
    It may well be the DPF or EGR blocking up and old engine oil does not help the situation.

    Even if you get the oil and filter changed this would be a start and also get the garage to check the fault codes to see what is logged in memory

    Let us know how you get on with it all

  2. Hi Don...welcome to the Forum

    It should be replaceable as an independent component separate from the rack.

    Any decent garage should be able to tackle the replacement but would need wheel alignment resetting afterwards

  3. There are usually lots of mods to carry over to a vehicle which was not originally equipped with Xenon.

    One of the major components which you may not have on your vehicle is the suspension ride height sensors which will dip the beams when a load is applied to the vehicle.
    If these aren't fitted then it may prove more of a task

  4. I think there are many different types of chips available including Tuning Boxes but the power gains are all relative to the torque increase which on a Turbo Diesel is the most important aspect of increasing power output.
    I used a Tuning Box successfully on a Honda and the drivability was so much better (smoother) and the only thing that was compromised was increased clutch slippage (auto adjust type clutch).

  5. If the speedo gets a reading from speed sensors built into the wheel bearing (which I don't believe were introduced into cars until a lot later) then if there was a discrepancy such as different rolling diameter (incorrect tyre profile size) then this could give an incorrect reading.
    However, if it took a speed reading from the ABS sensor then if the wheel bearing is worn then this could lead to incorrect speedo reading.
    I think you would hear a rumbling noise from the wheel bearing if it was that worn though, but worth checking.

    Also if the ride height is different from one side to the other then this could be a broken coil spring which is quite a common failure.
    Check the coil spring to see if it is all there and compare to the other side.
    Sometimes it isn't apparent that it has snapped until you jack up the body on that side and then see if there is a loose part of the coil.

  6. Hi Andy

    It may take the speed reading from the gearbox and this can happen when the drive is worn.
    From memory, it is easy to remove and check to see what condition the worm drive is in.

    Follow a thick drive cable into the top of the gearbox (could also just be a wire going onto a transducer but will still have the same plastic worm drive).

    Worst case scenario (which we used to have on Rovers) is when the final drive bearings drop due to wear and this can also make it jump
