Firstly sorry for my English. I'm from Spain and my English isn't good.
I think that I have a problem with my ignition coils. One of them could be failing and making a misfire. So I want to change my 4 coils. I heard that the coils for the Audi R8 runs very good in GTI V. My car is stock but in future I would like to reprogram it to stage I.

What do you recommend me? How do they work? Can I put these ignition coils without problems? I have NGK sparks too.
Thank you so much!

Is it absolutely necessary that the plugs are iridium?

Does it sound like I need to swap mine out to solve it?

Sorry to hijack the thread but I have noticed that when I accelerate hard it feels like I am getting a flat spot in 3rd gear. Its hard to describe. Its like I am hitting a rev limiter.

Is it misfiring?
Best to log with vcds to identify which cylinder is causing your problems :happy2:

Have ordered the coil packs and plugs today

Data logging the car will identify any misfires or errors. You may be getting misfires that aren't enough to trigger a light on dash / fault code.
That seems to be my problem at present - which has now been identified as misfires on cylinder 3. Hopefully I can swap the coilpack and that'll sort it - only had the injectors changed 5 months ago.

Yeah it's bothering me and always has that there is an issue there. Finally had other things sorted and decide I need to tackle this. Saw the packs and plugs were relatively cheap so might be worth doing anyway as neither have been changed whilst under my ownership

Hope the new plugs & coils sort the issue mate :happy2:

At idle mine sounds fine.. DV and PCV recently changed... All sounds fine and feels fine until I accelerate hard and every time I do I get the flat spot. Usually when heading up a slip road onto a motorway so it kinda has to be taken into account when planning on accelerating hard
Your problem could be in the fuel pump or in the N75 valve (I think). You should do a data logging with vag com.

Knock Sensor (G66)
Is it a big problem? could this be causing the vibration at idle? Should I fix it immediately to avoid a bigger problem?
I thought it was because the ignition coils
