Any fix or solution to this? Mine is doing same thing. I wonder if there is a fueling lockout due to low oil pressure as in maybe its a dodgy oil pressure sender.
I still think this could be a culprit.oilhammer said:Sounds to me like the ECU is randomly seeing a brake pedal apply signal and doing exactly what it is supposed to do: return to fixed high idle.
I would scan the car every morning to see if the sensors are reporting the correct temp.All the temp. sensors showed plausible values though, i wonder if one temp sensor is intermittently acting up, telling the ecu that its -40 or something stupid which cuts the gas pedal to act as a fail safe to prevent loading the engine when its super cold out. anyone know of any temp sensors which are common fail items on these cars?
It may be new but if there's a bad connection or frayed wires the end result is the same.No pedal response issue still happening intermittently, the TPS is brand new.
That's what it is. I've had frozen actuator, read many a thread here, can't imagine the turbo doing that. Maybe the tandem pump, but seems unlikely. My monies on wire/connect at something like the brake switch...................snip.......................
Something in the ecm programming is not allowing normal operation due to some condition not being met.
I can't speak for others, but I can note that in my case the car did this both before and after a brand new turbo (with actuator). I was thinking it might be related to the 09A in some manner, but it seems that others with manual transmission have the same issue which would rule that out.There's a VW bulletin about the actuators rusting internally.
Not sure if yours has this problem or not.
Doubt it.
If you are working on the BEW car in your signature, the only thing operated by vacuum is the turbo actuator, an intake flap valve which only closes a small portion of the port and a diverter valve for the EGR cooler. None of those things would cause the accelerator to just not operate. You could disconnect all of those items once the car passes the no-accel episode and the accelerator would rev the engine
There is no vacuum connected to the ECU on these cars...not since 1998.
