530d Engine Carbon Clean

What are your thoughts? Is it worth it to clean? Because today i've seen an ad about engine carbon clean, then i read some feedbacks which were all the way positive, but the vehicles been only seat, vw, audi... So wondering if anyone did this maintenance? What were your thoughts about it? Here i've seen that guy comes with his car and does it straight away, which cost 99 have no clue if 99 worth it or its over-rated? if someone has done this before please spread your experience here

Which cleaning method does he used, walnut shell blasting or just a solvent? Does your engine need it?

I would not consider carbon cleaning a regular maintenance item and I would be suspicious of any company that has a mobile unit that does this kind of work.

It sounds like they run a highly refined solvent gas mix thru your engine to clean the carbon, for direct injection engines, they inject solvents into the air intake manifold to clean the valves. I had a Audi dealer perform this service on my A6 before due to a CEL, it will only work for very minor build up or if you do it as a regular maintenance since the car is new. For more severe cases, walnut shell blasting is require.

The problem with diesels and with gasoline engines with direct injection (e.g. modern BMW's and MINI's) is that the injectors are inside the combustion chamber, not upstream in the intake port of the cylinder head(s) or intake manifold where they can spray the intake valves and intake ports with detergent rich fuel.

Here's a DIY video. The important thing is to make sure the intake valves are closed before blasting, so you don't fill the cylinder with the blasting media.
