Another thought for those who are more knowledgeable than me. Could it be that all this is intended and that the switch must be NO in order to bring the engine from Euro4 to Euro5? This has worked in the sense of a castration of quality to make the engine leaner but unfortunately some engines develop bad symptoms of accelerator pedal dropouts which are accepted as collateral damage?
Best theory about the second switch yet, Heinz, especially given Uther’s comment. Perhaps the experts can tell us when Euro 5 production started, and We could get owners to confirm whether they have the second switch
So if the switch begins to fail, (no current passes), we would get power loss.
But if this is correct, how come your car operates when the wire is disconnected ?
