Hi,
I've recently started experiencing an issue with my 2009 q7, the engine stalls when accelerating and the car will not go over 30 mph. this usually follows with a kick/jerk and i have to stop and restart the car for things to get back to normal. There are no codes and I've brought it in to the dealership and they cant seem to diagnose the problem. recently i was doing a little research on the issue and read on the Throttle position Sensor (TPS), i'm thinking this is the problem as the description of this issue fits exactly what I've been experiencing. Have anyone experience this issue with their Audi? Any input is greatly appreciated.

Thanks!

Which engine?

I have almost the same problem on my 2008 q7 3.0tdi.
It stalls when it reaches operating temp.
New HP pump, regulator, filter and crankposition sensor ...
If I unplug the temperature sensor, the fan blows all the time and the engine does not reach operating temp, resulting in no stalling...

We had this issue when we gapped our spark plugs above 0.4, we got best fuel and best power at 0.28 gap on all spark plugs. When we happed spark plugs at 0.7 everything on the dash would light up when you try to speed up above 30mph and car starts to try to want to stall.
