Hi All. Has anyone ever had this code flag up on diagnostics: 18047/P1639/005689 - Accelerator Position Sensor 1/2 (G79/G185): Implausible Signal. My Avant runs well (good service history, now on 140k) but has a slight hesitation now and again on brisk acceleration. At first I thought it may rev related as it is between 3k & 4k (I never go over 4k), but as this is the only fault code I have I beginning to think the two could be linked. Could it be the case that the slight hesitancy might be to do with the pedal position during acceleration, and nothing at all to do with revs?? The Ross-Tech website thinks the following: Any thoughts would be appreciated folks. The car runs great but this intermittent fault is frustrating!
