After getting my car through its MOT yesterday, I thought I'd take it for a drive. The car has hardly any power and considering it's supposed to have 230bhp I would have expected it to manage more than 40mph up an incline! Scanned it with OBDeleven and came up with fault code P0905 and P242F (DPF restriction) After I clear the fault codes and its in park then the computer displays clearly that its in P position. When I push the button on the side of the gear stick and move it down it shows the gear position on the display until I get to drive (D). When it's reached that position the indicators on the computer screen all turn solid red, they don't flash they just turn solid red. I can move the stick to sport and the car revs higher before changing gear so I presume I actually selected sports. If I select tiptronic the display doesn't change and stays solid red, it doesn't display the gear number, I've not tried to drive it in tiptronic yet, maybe I should try that too? I have taken the gear shift to pieces and can't see anything burnt out on the circuit board. The magnets are still in position and I can't see any damaged wires. The next thing I think I'm going to do is check the wiring from the gearbox control (J217) unit to the tiptronic switch (F189), then the rest of the cables from the gearbox control unit to there point of termination. This is going to take a while so if anyone has had the same problem or can give me some advice on my next move then please let me know. Also the lack of power issue, is that due to the dpf, gearbox fault or is it more likely to be something else? Please give me some help if you can. I will put all my findings on this thread. Thanks!
