I understand your reasoning and share your frustration Dave at sending the car to BHM. Without fault reporting you are working blind and that for me would be intolerable on a modern DBW car. I'm also a little concerned that yourself and other GDI owners could be driving with an engine in potentially dangerous condition without any fault reporting!

No consolation but a new accelerator pedal sensor appears to have fixed my Roadsters random but increasingly regular severe throttle response issue causing misfire, which corrected itself every time with engine off for three minutes. There is a barely perceptible improvement of gentle power take up when driving in built up areas, when fault nearly always appeared. I'm guessing the twin potentiometers on old sensor had the equivalent of a scratchy volume control pot (however rare) as fault always triggered the same P2135 voltage correlation error code but with no freeze frame data recorded.
