Nuts to clean it.

[Delboy]

The internet is awash with horror stories as we know but one of them in paticular has managed to sow the seed of doubt in me grey matter.

The FSI engines as we all know are direct injection and because of it the inlet valves don't get cleaned by fuel passing over them, this combined with the crankcase gases being recycled to save the planet blah blah all add up to the perfect recipe for coke buildup.

Has anyone here had theirs cleaned and if so what kind of mileage and state was it in.

Read a thread on another forum of an rs4 losing 100bhp because of it.

Because of that I am considering get the car dyno'd to see if I am down on power and if it is thinking of getting the equipment to blast the valves with walnut shells.

Thoughts?
