I just bought a 20k mile 2010 Jetta TDI 6MT and am loving it, aside from one quirk when driving at freeway speeds. Sometimes when lifting off the throttle (usually downhill), OR USUALLY when hitting a dip (even pretty gradual, like between two hills), the car has a tendency to noticeably slow down as if I were hitting the brakes.. without me hitting the brakes. It is far more pronounced than normally lifting off the throttle, and reminiscent of an exhaust brake on a truck.
Does anyone know if the engine management in these cars is programmed to close the exhaust flap under certain conditions to increase engine braking? Or maybe the anti-shutter valve?
Does anyone know how I'd log exhaust flap operation? I dug around in VCDS a bit and couldn't find anything obvious, though I'm far from well-versed with this particular car.
Thanks for any info
