’06 Jetta TDI BRM has an intermittent issue where the throttle is not responding and engine speed is reduced to idle rpm. This occurs while driving and in park revving the engine. Once the accelerator pedal is released then response returns. Typically occurs when the engine is in the 1500 to 1900 RPM range.
No CEL indication or other abnormal indications. VAG-COM shows there are no DTCs.
Monitored the accelerator pedal input for Throttle Position Sensor and no issue as the indication increases throughout the range of 0 to 100% without signal dropout.
I read that an ASV problem could possibly be the cause but unsure of this. The ASV cycles when the key is turned off as it should.It may be a coincidence but I unplugged the ASV, revved in park as well as drove the car and the “no throttle response” did not occur. Could it be the ASV position signal to the ECM is an issue prompting the engine to go to idle speed?
This evening I plan to monitor the brake switch input to rule it out. While in park I did not notice the green pedal indicator light on the panel going out but I want to monitor the input to make sure.
Ready to purchase a new ASV but would like a bit of input from you guys if there is anything obvious I am missing or additional checks I should make.
