Hydrogen engine carbon cleaning

My B7 RS4 is booked in next month to get carbon clean via the elbow grease method stripping down and cleaning by hand.

Had previously looked into Terraclean but didn't think it was worthwhile doing.

Noticed recently this hydrogen carbon cleaning method where water is converted into hydrogen and injected into the air intake. Engine then run for 30 mins or so which breaks down the carbon deposits and they come out the exhaust.

Have any RS4 owners used this method to carbon clean their engine and did they find it made any difference?

Hi mate,
What makes you think Terra clean is not worth it, my mate does this and swares by it.  Just asking as I was thinking on getting this done. They done it on Wheeler Dealers are you telling me Ed China is lying to me

Terraclean will clean the injectors and fuel system - but is downstream of the inlet valves so won't touch any deposits on them.

Got you. Hence strip clean. This will cost though. I suppose Terra Clean will be my cheaper option.

Terraclean will be fine on the B5 for cleaning the fuel system - just not on a B7 RS4 for removing the carbon build up.

Does anyone know if newer Audi FSI engines still suffer from this? Or did they come up with a fix?

Hydrogen? Sounds like smoke and mirrors. Looks like it uses electrolysis to break down water into its component parts - hydrogen and oxygen - and squirts that into the intake then it's most likely the oxygen that's doing anything. A hydrogen and oxygen mix is very explosive by the way. Wouldn't want that in any volume going into my cylinders thank you.

And electrolysing on site seems like a clumsy way of getting hydrogen when you can just get a cylinder from your local BOC distributor. Good for filling balloons too. So long as you don't pop them with a lit fag.

Terraclean (possibly after taking much stick from the more technical minded) now have a 'device' that injects to inlet supposedly helping with the FSI issue.

My gripe is this. One of the main claims obviously is improved/restored performance. They are now probably into the hundreds of thousands if not more cars treated... not one back to back dyno test pre and after treatment.

Why not? It would silence the cynics overnight.

Like other boys have said terraclean only cleans fuel lines and will not clean the carbon build up as fuel injected direct into cylinders downstream of the carbon deposits.

As far as I know all VAG engines will suffer to some extent due to fuel being injected directly into cylinders and the egr pumping crap back through intake for emissions.

Audi are well aware of the carbon issue especially with the RS4 as a technical bulletin was issued to all dealers.

However when I asked by local Audi dealer about resolving the problem the "RS specialists" told me to use good fuel at which point I burst out laughing.
They told me this would wash the deposits away but went suddenly quiet when I told them the fuel is injected direct into cylinder and does not wash across valves.

We are offering a strip down carbon clean for 300 all in at the moment on b7 rs4's.
Dare i say the same method as some very well known tuners.
DavidT

You dare, but if you want to advertise your products and services here, you will need an advertiser package as those well known tuners do
GINGER_JACK_RS

Im sure that was the case, hence i never put my company name. Can you pm me the prices please buddy?
