Hi Guys
I am new to the forum but have already learned much from what many of you have written here...Thank You.
I have the code from VCDS :-
004203 - Throttle valve
P106B - 000 - Stuck or difficult to move - intermittant
Having investigated the Air Control Flap at the front corner of the engine on passenger side (not the Throttle Valve as described in the code readout - this is a deisel engine I am not sure why VCDS calls it a throttle valve) I find that the crappy plastic gears are stripped and that the motor in the actuator cannot move the very clean valve in the Air Flap Valve body cos there are no teeth left on the gears.
There is no apparent reason for these gears to strip.
Does anyone know why these gears strip?
This is a terrible design using plastic where metal gears should have been used.
This is a 2007 Q7 with only 56 k miles!
I have ordered the replacement 059 145 950 A at £234 ouch!. Luckily this looks to be an easy item to fit.
My main question is......
Do I have to perform the re learn routine from within VCDS on this Air Supply Control Flap when re-fitted?
Here are the pics of the crappy gears.....
Many Thanks for your help
