    As title no kickdown, makes no difference in comfort or sport mode, can still select manually with the shift. EPC visit workshop shown, with 150k miles does this mean big bucks? I have had the transmission fluid changed every 60k miles

    I would guess you won't know what's involved until it's had any fault codes read by STAR at an indy or MB . Good luck with it all

    Don't you think that is enough! This car has been very reliable, and from what I read on another thread, the five speed box is too, maybe it won't be such a big issue, I will keep everybody posted anyway.

    Probably an issue with the fuel system, my guess would be an injector or the high pressure pump

    I think you'll find that when Bembo asked that question he knows that when kickdown is faulty there are often other noticeable symptoms occurring at the same time. These give a further insight into the possible reasons for your problem.

    So his question is not yet answered.

    Oh, ok, I'm not sure but I think third gear is not selected unless I use the selector to manually go through the gears, all will be revealed this incoming week I'm sure, and I will of course keep you posted. Thank you very much for your interest.

    Well, the results!
    Fault caused by pressure sensor for DPF: £101 for fitting same+ £53 for said sensor.
    I have used the main dealer simply because, (a) courtesy car always available, and (b) I have 30 year roadside assistance, the latter I assumed I had foregone as I had used an Indie for a couple of years, and last year the waterpump packed in just a few days before we were due to drive down to Preston, and panic set in, I called the main dealer who informed me that I had 30year roadside assistance, I think he made a mistake, but why argue! Soo the moral side of me came to the fore, and now unless something unforeseen happens I intend to continue with the main dealer. The breakdown van came here yesterday morning, the guy connected a box of tricks to the car, brought a laptop and clipped it to the van steering wheel and read the codes wirelessly, and gave me his likely prognosis. Nothing is free of course, that test at home cost £27.60 + £82.80 to perform a further test, presumably after the new sensor was fitted, all in all including vat £317, I'm sure the Indie would have cost less, but more hassle for me. In the scheme of things this was buttons after 151K miles I suppose.

    Good result in the end ...and everyone has their own reasons for their service partner choices ...
