Coil pack and spark plugs

Hi guys just looking for some help, I have taken plugs out of my engine today as still can’t find who has mapped my car as had a feeling it may be running rich, spark plugs were changed by Audi 6k ago and are 079905626L plugs. I have taken a picture to show the condition and would appreciate any advise.

Colour of plug is grey on the end is this ok.

Cheers

Depending on how your RS was driven before you removed the spark plugs that colouring is fine tbh mate.

If the car has been left idling for sometime or been in stop/start traffic the plugs can go sooty but will clean up on a motorway run.

Thanks Dell still getting to know the car, as still can’t find who has done the tuning work on it. AMD Essex have a picture on their website which I’m sure is my car but they can’t tell me if it is without previous surname and address which baffles me. They have confirmed though that the lock the Ecu like mine is.

If you need it unlocking then Ric at Unicorn is a wizard at that. I had a map on an Audi A3 TDI that was awful. It was locked by the previous tuner who refused to unlock it unless I paid him a bunch of cash. Took it to Ric ,he unlocked it in 2 minutes.
