Does this actually work? or is it that someone has come up with a solution to a problem that doesn't really exist and are marketing it as a revolutionary process that will enhance performance and boost your power output?
good if it works though , sounds conkers.

Its an N54 thing. The walnut blasting removes oily carbon deposits on the inlet path. EGR causes the inlet path, over time, to gunk up restricting air flow/causing turbulence than can result in poor running and therefore efficiency and smoothness. The walnut blasting is to remove this accumulation and restore the engines performance. good if it works though , sounds bonkers.
Its not a nice job and is usually left to a specialist but on cars running poorly it can make a large difference from what I've read. Its not cheap either. This is a result of emissions control and direct injection combining to empty wallets.

Yes it does work. Heads/valves have started coking again because of the use of direct injection.good if it works though , sounds bonkers.
The reason why it works is because you need something hard enough to get of the st and soft enough not to damage anything else. It's that or the head off to have it cleaned.
I assume it's not real walnut shell, just some soft blasting beads.

Good timing, I'm looking to get this done on my N54, does anyone know of a place in Scotland that does it?
Don't know about Scotland but i'm getting mine done @ Graham Martin Automotive Ltd BMW & MINI Specialist Jnc 7 M62 St Helens 01744 735993 WA9 5GZ www.GrahamMartinAutomotive.co.ukI used them to fit the Diff and do some other work & have to say i'm quite impressed.
We use very fine ground walnut shells for cleaning gas turbine rotors at work.
Wouldn't want to be paying a lot of money for it, the process is quite literally pouring the shells slowly through the air intake while the machine is running, to clean a large gas turbine normally only takes a few kilos of shells and they are dirt cheap.
I would want the oil changed after, the dust from the shells has a habit of getting into all sorts of seals if done excessively.
Good luck

The N55 is DI, but also with Valvetronic and doesn't suffer from the same coking up problem.
