3.0TFSI tune up - coils and plugs

On my S3 8P I had same errors. It turned out to be faulty Injectors. It was totally random, sometimes under boost, sometimes not. They found 2 that where acting up. Changed the set and no problems.

Good to know.

I will wait and see if it pops up again and then pull that plug and post a picture.

I run the iridium 9 cold level in summer. No issues in two seasons.

This is a good point. Running colder plugs with increased hp is always a good idea.

Hoping this I’d it, keeps coming up on send cylinder and have swapped coils and plugs. Totally random as well.
