Today I made a trip to VAG Technik and I got myself Audi R8 coil packs and the Auto Polar FIS Advanced module http://www.auto-polar.com
The coil packs did not solve my missfire issue, I will now replace spark plugs and hope it solves the issue. No one has stock of the BKR7EIX plugs so maybe I'll go back to stock plugs (guys in the USA from APR & REVO are running stock plugs up to K04 with no issues) Thanks to the Polar FIS I see that the missfire is on cylinder 4..
It really is a epic piece of kit! In the MFD I can now view things like boost, timing, oil temp (I could do this before) oil level, intake temp, radiator temp, exhaust temp, fuel pressure, rpm, actual km/h, air flow (g/ms) and the list goes on and on! Even a g meter for cornering and a timer for 0-100 speeds or higher and a lap timer. Also it enabled my video in motion for the RNS510.
Was a b**ch to fit, tried through the footwell to get to the CAN Gateway but that did not work out at all. Then I removed the wipers, rain tray cover, wiper motor and arms and then got to the access cover. Popped it off and plugged the module in..
Before I re fitted everything I noticed my ECU is not very secure (this could be the damn rattle I hear when pulling away at 1 500rpm that has been unsolved for almost a year) so I secured it and it seems sturdy now. Still to check if rattle has dissapeared or not.
Fixed the misfire. It was my plugs that were shot. NGK BCP7EIX and they were tired after 10 000km. Ridiculous.
So I am back on the OEM Bosch plugs which is also preferred by REVO & APR in the USA up to K04. They have tested it running BCP's and BKR's resulting in misfires and timing pull then swopped back to old OEM plugs and the car was fine again.
