Walnut blasting valve cleaning

From what I gather it's 50 000kms or every 3 years. I will be charging 325$ for the cleaning using the approved method with new intake gaskets. Willing to package the service with oil filtre stand gasket as well if needed or if you wish to do while I'm there. There are quite a few people who have asked me for the service so I've decided to invest in the proper equipment.
 
Sound good I will have to time this with summer vacations since I am from Sherbrooke... I sure many MR Direct Injection car owner will ask you for this service!
 
I am at 80k kilo and my car run and idle fine. Doesnt the N55 have 1 more injector to clean the valves?

I don't know about the injector but the car adapts to run fine even if it's full of shit in the valves. You then see a real difference after cleaning.

Audi have put an injector in the intake manifold but BMW didn't... N55 might not get dirty as fast as N54 does but still they will build up carbon.

BMW only or audi too ? :)
 
Yea and at what KM you recommend this treatment for the N55, how fast do those build up carbon? Mine is around 65K KM now...

Getting my N55 with 82,000Kms done on Mar 5th...
Car has seen the track for about 1/2 of the mileage, running a custom tune, and received frequent oil changes ...
Will try to snap before and after pics. , if Gregster allows me, and I will post them here ...
