got some new questions ! can anyone tell me when Peugeot Aust stopped using Sagem coil packs and went to electrofill as I have been told Peugeot dropped Sagem as they are faulty,also I have heard that a wiring modification is required when swapping to the Electrofill coil pack?

Is there any non dealer repairers in Sydney who can do this as well as ECU upgrades, any ideas on how much this would cost, as my dealer said that he replaced the coil pack in December 2004 and when I checked yesterday what coil pack I have,I found a Sagem and information given to me stated that Peugeot dropped Sagem a few years ago.
Also is there anywhere in Sydneys north to get parts ie plugs and filters other than dealers.
Any help would be great.
