Any suggestion on cleaning carbon deposit buildups?
Hi there,
I am looking for fuel additives to clean out the carbon deposit buildups inside the combustion chambers. Any suggestion or recommendation on brands? :rolleyes: |

There is a thread on the vortex in the Ontario section regarding engine cleaner for carbon build-up.
Try the Motul engine cleaner, and install a catch can in FSI motors ASAP. These are direct injection engines and thus do not benefit from the fuel cleaning/lubricating the intake track. Catch cans virtually eliminate these issues. The last time I was there, Euroline Performance have FSI specific catch can kits with all the fittings etc that are easy to install. |

I've been told nothing will clean the deposits ... period. You gotta pull off the mani and scrape away the carbon or bring the car in for a proper cleaning. Apparently avoiding ethanol, using a catch can and driving it like you stole it will help reduce deposits ... Amazing the benefit of a proper cleaning had on my RS4 !

What would they do for "a proper cleaning?" How much would that cost?

Add Techron from Chevron to your gas. It will clean it to pure metal.
You probably need to bottles. The car will lose performance during the process but you will clean that carbon. I do not recommend cleaning the carbon unless when you turn the car off it still runs for a second or two. Some carbon is good for the engine since it seals the leaks of pressure and makes the rings on the pistons fit snuggly. When you clean the carbon the engine will be noisier for a long time. |

There are plenty of claims by product manufactures that their product will remove carbon build up. The only way I know that you can adequately remove carbon is by physically doing so. Using non ethanol fuel like Shell 91 will reduce the carbon build up. Drive it like you stole it once in a while is what was suggested. |

Thanks mikeh! I understand the new Audi engines are all prone to carbon buildup (as well as Porsche one); however, a 10-15% loss of power over time is far more noticeable on a 420 hp RS than on a 210HP A4 ...

Add Techron from Chevron to your gas. It will clean it to pure metal. My 07' 3.2 A4 has 72,100km on the odometer and I'm starting to wonder if its getting to be about time for a proper cleaning. I'm getting a bit of a fuely smell on startup, no misfire codes yet though. Power seems to still be there. If you stand on it it definitely puffs a bit of carbon. |
