My car has been at the non-Audi supplying dealer for the last 3 days whilst they change the thermostat and took a look at the "17439 Manifold Change-Over Valve (N136): Setpoint Not Reached" fault code.
They have spent today taking the inlet manifold and throttle body apart and found no visible signs of clogging or worn parts.
They say they have spoken to the local Audi dealer who asked if I use super unleaded or normal 95 RON (I use 95). They say the reason for the fault is because I'm using the wrong fuel in the car and all FSI engines work best with super.
So is this true or just a load of tosh?
