On the 2015-2019 Volkswagen Golf GTI, on the MK7 Golf GTI and its EA888 Gen3 2.0T siblings, the intake manifold carries a set of runner/tumble flaps driven by an electric actuator, and a small separate potentiometer-type position sensor (VW designation G336, commonly part number 06K907386D) reports where those flaps actually are. On this engine family the sensor is a separately available plug-in unit rather than a component you can only get with the manifold, and it sits low on the manifold in a hot, oil-misted area of the engine bay. That location is part of the problem: oil mist, road spray and heat cycling attack the connector pins and the sensor's internal wiper track, and the signal starts dropping out. Owners describe a textbook intermittent pattern rather than a hard failure - the MIL comes on, the code stores as P2014 (VW freeze-frame often shows it as P2014 00 [172], 'electrical malfunction'), the light clears itself after a week or two of driving, then returns after the next cold start. Because the ECU is only losing the feedback signal, not the ability to command the flaps, drivability stays close to normal: the car still pulls, but the ECU parks the flaps in a default position, so owners typically notice only a mild loss of low-RPM crispness and a small drop in fuel economy. The real consequence is emissions inspection - a stored P2014 with an illuminated MIL is an automatic fail. The important diagnostic point on this engine is that P2014 here is usually the cheap failure, not the expensive one: the well-known VW/Audi intake manifold replacement is associated with P2015 and P2004 (flap or carrier plate mechanically broken), whereas a clean P2014 with no P2015 and no P2004 alongside it points at the sensor or its connector. The same sensor and the same fault appear across the platform - Leon Cupra, Golf R, Jetta/GLI and Audi 8V/B8.5/B9 cars share part 06K907386D.

How to Fix
Diagnose before buying anything. With a VCDS, OBDeleven or equivalent VAG-capable scan tool, put the ignition on with the engine off and watch the intake manifold flap position measuring block while the flap arm is swept through its travel. A healthy sensor produces a smooth, continuous 0-100% sweep; a failing one shows a flat line, a dead spot mid-travel, or an instant drop to zero. Wiggle-test the connector while watching live data - a reading that glitches when you move the harness confirms the connector rather than the sensor. Before replacing anything, unplug the connector, inspect for green corrosion or oil intrusion on the pins, clean it with electrical contact cleaner, and re-seat it; forum consensus is that a meaningful share of these are fixed at that step for nothing. If live data confirms the sensor itself, the repair is genuinely small: the G336 sensor is sold separately (06K907386D and supersessions) for roughly $30-100 (about GBP 80 for a genuine unit), and access is from below after removing the belly pan, with the oil filter housing area cleared for hand clearance on most cars. Budget about half an hour to an hour of labor. Buy an OEM or reputable-brand sensor - cheap aftermarket units are reported to fail to clear the fault. Clear the code and drive at least one full drive cycle including a cold start and highway load before assuming success, because the fault is intermittent and will not reappear immediately. If P2014 returns with a companion P2015 or P2004, stop chasing the sensor: at that point the flap linkage or carrier plate inside the manifold is mechanically failing and the manifold assembly itself needs to come off.
