Talk to me about carbon build up on a6/s6...

[Stuno1]

I have been reading more a out s6's and seen some horrible pics and read some shocking stories! Apparently needs clean every 15k miles to clear carbon build up in the engine!

Is this the case? Is it an expensive job? Do all a6/s6 cars suffer from it?

More digging suggests using a high octane fuel may help as it contains fewer contaminant.

Also, £750 for a carbon clean so not too bad. Few hours labour for identification.

All FSI engine suffer from it. Mine has.

High octane fuel won't do enough. Nor does standard Terraclean.

I'm in the process of having a new form of Terraclean done to mine. Will report back when its done with the results (probably be a few weeks yet).

Few weeks! Was it in a really bad state? Expensive job? How often is it needed?

 

[Stuno1]

What is the normal type of cleaning needed? Where can I get it done? Any idea on price?

Try MRC, they're doing this all the time on B7s
