Air Flow Meter Harness
They are back! Pleased to see VW Germany put these back in production. Still not the most affordable but pleased to see that they at least came down from $337 price that VW U.S. last was selling them for. Please read bulletin below to confirm this part is recommended to repair your symptom and to be aware of the less expensive alternative fix.
Official Technical Bulletin: Condition: After driving for an extended period of time at a constant speed - the vehicle may - on occasion - experience a deterioration of performance which may be accompanied by a hesitation or surging. In many cases - after turning off the engine and subsequent re-start or without having taken any action - the symptoms disappear. These symptoms may not recur for several weeks or months. To resolve this condition - wire harness Part No. 025.906.302 - should be installed. This harness provides improved signal voltage stabilization. Please note that there is an alternative. It is well documented on various forums that the same result can be achieved by soldering a capacitor inside the air flow meter. You can either research it and do this yourself, or you can send your air flow meter into us and we will perform the modification for $45 and send it back to you promptly.
