Hi. Whilst driving yesterday the car, a 1.2 12v 3 cylinder mk4, dropped down on power dramatically and limped along for a mile before stopping completely. It would sometimes start and sometimes not thereafter. At first my OBD2 reader reported P0606 ECM fault and P0341 Camshaft sensor signal. I had the car recovered. When the recovery arrived it was no longer reporting P0606, and was now reporting P0341 and P0302 (misfire on 2). Unburnt fuel in exhaust was easily smelt. The coil pack on 2 was replaced by me last year with an off-brand part last year. I've also replaced the other two with bosch and VAG marked coil packs respectively. When I got home I swapped the coil packs and the car started OK but any throttle above ~1000 leads to stalling and p0341 is reported again. I've ordered another bosch coilpack. Now I'm thinking I should first replace the camshaft sensor as that's the main fault and be prepared to change the coil pack. It's cheaper for me to replace it rather than buy kit to test it or pay someone else to do that I think, and not too hard to do I believe. What is the OEM manufacturer for the sensor and part number for it. Should I buy a 'known' brand for this part? Is there anything else I can do to confirm it's a bad sensor rather than another fault for example can I bypass or simulate the camshaft sensor? I do understand the purpose of the sensor and the risk that if the timing actually is out the damage ould be catastrophic.
