Not pretty sure if I can bare with the carbon build up problem and opening/cleaning the engine every 20K miles.

I've been lurking in the RS4 forums and all they found was a catch can or the recirculating unit as the solution. The latter does help, but only by a tad. Has anybody found a fix yet?
Every 10k miles I take a snake scope into the cylinder head and check on the valves. Most of the time I find relatively low carbon build up. Pretty much every Audi FSI engine has this problem to an extent. Does this prevent me from enjoying my car? Hell no. I think the minor inconvenience is worth it. Odd because sometimes I can't feel a discernible loss in power, but I still find carbon deposits. I'm also waiting for an effective solution. For now, this will do.
