    Icon5 Should a 308 tiptronic change down automatically in manual mode ?

    Hi

    I have a 308 2.0 HDi auto and noticed today when I took it for a short drive in manual mode [very rare] that when slowing down to a stop or give way sign that it would change down by itself e.g. if I was driving in M4 or M3 it would change down to M2 or M1 etc. I see this on the display

    Is this how it should work ?

    I ask as we had some warranty work done last Dec that required the gear box out and since that work we notice on occasion in auto mode [D] when coming to a stop there is a small 'donk' from the gearbox as it it has finished late changing down to 1 or disengaged the clutch

    Do I have a problem ?

    If it might be a warranty item, and you are under warranty (the "small 'donk' from....", for example) I'd put it to them and get them to prove otherwise. Might be fine or might be precursor to trouble out of warranty. So why would you not go and ask the question?

    Then, others will give tech advice here to help your interrogation of the dealer.

    Good luck.

    Thank you for the reply

    Before I assume a warranty issue I'd like to know whether my auto gearbox changing down in manual mode as outlined above is normal

    What I can do is take another 308 auto [from the dealer] for a drive and see if it exhibits the same behavior in manual mode, if not then yes I can put it too the dealer

    It is normal. The gearbox will override your selection to prevent under/over-revving the engine.

    From the manual:

    ...
    In the event of under-revving or over-revving, the gear selected flashes for a few seconds, then the actual gear engaged is displayed.
    ...
    When the vehicle is stationary or moving very slowly, the gearbox selects gear M1 automatically.

    I also found with my 607 that even in manual mode it won't let me use 100% throttle at low revs. The damn thing assumes that you are doing some kind of "emergency" accelerate and drops from 4 to 2 even though you didn't ask it to.

    It's a big torquey diesel and so I would like to waft around at 1500rpm or so and use all of that diesel torque. The gearbox just won't let me

    Same applies to the petrol model. Go to slow in a gear and it will auto change down.

    Our 1.6 EGC Diesel also changes down automatically in Manual mode. So does our Renault Grand Scenic and the Mazda 6 we had prior to the Scenic. Have a read of the manual, it sounds like a version of adaptive control and probably also changes down if you're going down a hill and do more than touch the brakes.
