Hi All, I have a VW Lupo 1.4TDi which is remapped to approx 100BHP. The car pulls well for its slender weight, however has an issue going to Limp mode. It hits limp mode usually going up hill and a constant partial (30-80%) throttle for around 5secs. If you modulate the throttle, even slightly, it will be fine. The error logged is a Positive Deviation error (i think, i actually forgot!). The N75 makes a LOUD ticking noise audible from the cabin when the ignition is on (not engine running) - is this a problem? Ive had a visual/audible check for boost leaks and cant seem to see any at all. Here are my logs at full/part throttle hoping to find what is going on. Notice that the car meets (and exceeds) requested boost at 100% and as such the duty cycle reduces (goes up on the graph)... At part throttle however, the duty cycle is almost maximum (Low on graph) but Actual never meets Requested!! Any ideas please shout! Many thanks all for reading! Full Throttle: ~50% Throttle:
