Hey there, I was wondering if anyone has tried or had a carbon engine cleaning for their engine?
i had a “Terraclean” done on my old A5 but wondered if anyone used this before and what they thought or is there something better out there?
Thanks

Walnut blast is really the only way to go...

He's right, I did some chemical carbon cleaning on my 2.0t and when I had to do the timing chain it was clear they did next to nothing...
