Walnut Blaster Service for 135i/335i/535i
Price: $599 (people say dealers charge $650-$800+)
About VAC’s Walnut Blaster Service:
We use factory BMW tools to perform this job. These tools ensure the job is done
right the first time and that there is no mess. The intake manifold is removed and
all ports are cleaned with BMW factory tools and BMW approved walnut shell media.
The manifold goes back on and everything is tested/checked.
We chose our technician Frank to perform these jobs – he is a former BMW dealer
master technician who had the pleasure of being the go-to guy at his dealership
for S62 (E39 M5) carbon cleanup jobs. (google it) He is now the go-to guy for N54
Why do you need this service?
See the pics below. All BMWs with direct injection will have this problem. This
buildup can cause:
-driveability issues (stumbling, odd throttle response etc)
-loss of power
1. How do walnut shells fit in my intake port? They don’t. We use BMW approved
walnut shell blast media which is more like fine powder. This is ideal for cleaning
2. Will I start doing 70mph rolling burnouts after the Walnut Blaster service? No.
Depending on how bad your buildup is, you may feel an immediate improvement or just
a slight improvement. Rest assured that you will save yourself a headache down the
road – as severely gunked valves are bad, very bad.
3. Can my buddy spray it with CRC and get the same results? No. This buildup is
pretty stubborn, so the media blaster+walnut shell is mandatory for a proper job.
If BMW specs this service with a media blaster, one can assume this is the best
way of doing it.
