Walnut blasting?...anywhere from 500-$1000 if memory serves. Ex had her 2009 335 done...made a big difference (per her).

I had mine done at the dealer. But i doubt it works. They just add something into the petrol, which doesn't reach the intake valves with our direct injection engines...

Walnut blasting is the way to go. Had mine done around 80k km, no significant buildup.
