But when the key button is pressed and the ignition is triggered, the Twingo always starts !!!!!!!!!! So receiver side goes. Twingo – Initiale Bj 2001 / 75 HP / 16V No impulses are received at the coil for the WFS of the ignition switch. 12 V and mass are ok. (measured with alternating voltages – Multimeter / has to get me an Oszi first) Can the coil be supplied with sep. impulses ? frequency ? plug has 4 cable connections. Is there a occupancy schedule for this? According to many information in motor talk, there is no measurement yet. The failure went creeping, first every second start attempt went, then nothing at all. Exception: key at the key press at ignition. This always works !!!!!!! In the decoder box is a relay NEC EN2 – 1N1S ?? For which function ? Will the relay be replaced, or does one of you already have more insights??
