I would advise anyone running nology plugs to do the same or just put in similar OEM spec plugs. The problem stems from the fact they have no resistance, so it can play hell with the electrics, accelerating failures.

List of known issues...

Throttle Bodies dying.
Coil Packs melting/blowing up.
Radio Interference.
Intake flapper motor fault code errors

Think Alex should jump in and clarify the situation, i'm under the assumption the throttle bodies are not dying but VCDS has no way of telling you the spark plugs are at fault but for some reason says the TB is goosed.

Never heard of coil packs blowing up, who had this failure due to the plugs?

Nodz:
I'm running these since the last major service and have had the TB go on me... Is it urgent to change them now or can it wait til the service in September?

Id change them... its dead easy (when your watching someone else doing it  :smiley: )

George:
I was running Nology plugs and had throttle body symptons, I've swapped back to 7s now  :happy2:

Hurdy:
Steve Jr at Statller fitted some to a few cars including mine.

Mine also ended up with several faults showing including the runner flap and throttle body. They were swapped out for Iridiums and the faults never re-occurred.  :happy2:

The best combination for lower tuned cars seems to be R8 coilpacks and OEM plugs and for stage 2+ and beyond to swap to Iridiums.  :happy2:

Steve swapped out the other customers cars he fitted Nologys with for Iridiums too.
