Carbon Cleaning - How To Scrape and Walnut Blast your Intake Valves Audi 3.0T B8 S4/S5, A6-8,Q5,SQ5

►One major drawback to all modern-day direct-injected cars is that carbon deposits build up over time and need to be removed at regular intervals. Carbon buildup is due to the fact that fuel is not injected over the intake valves like in a traditional port-injected car, but instead injected directly into the combustion chamber.
In this DIY, Cory Calvin shows us how to clean the intake valves of the detrimental carbon buildup on a 2013 Audi S4 with the 3.0t engine. This DIY is generally the same for other B8 model S4, SQ5, S5, or any Audi with the 3.0t Engine.

Just to let everyone know. The video on Pcv valve did not tell you to hold the intake flaps slightly open as you install the intakes or the flaps will get stuck closed. Try to actuate your flaps after the intakes are down on the injectors. Make sure they move freely.

Get ready to be cussing and throwing tools. This job is a PITA. Highly advise doing the extra work and putting the front end in the service position. If you have an SUV, you already have the extra room. S4, A6 etc have the front of the engine jammed up against the radiator and you MIGHT be able to get a finger and a half in between it and the engine.

One of those revisions being low pressure fuel injectors sat in the inlets in the old school way. This would alleviate this carbon build up on the intake valves! The later gen CREC engine had 12 injectors! 6 DI high pressure injectors and 6 inlet low pressure injectors. Plus many more upgrades.

The simple lack of fuel passing thru the valves in all direct injected engines is what causes the buildup of carbon. An oil catch can and slow the process but not prevent it. Methanol injection, however, will help keep the valves clean.

@@DaTT78 I could be wrong and correct me if I am but the Audi coverage I think you're referring to is a different carbon cleaning and has to do with the secondary air injection system which does not include the intake valve cleaning. I believe in order for Audi to cover this, you must get a "hard fault" which triggers the check engine light and 2 codes must be present upon diagnosis, this requires bumper to be in service position to get to the two ports...very common issue and coverage I believe is 10 years or 120,000 miles whichever occurs first Also don't bring to Audi for this unless you have the coverage...$1400 is far too much for a simple walnut blast/chemical cleaning....you should be able to find a good indy shop to do it for about half that and if you're hands on just DIY and save more of your hard earned $$$ 🤙

If you haven't had that one done yet it would probably be worth looking into as a preventive measure! If you're in this area I can give you the name of one Also worth noting: the cleaning itself should be in the 700 range but keep in mind that the injector seals, upper and lower manifold gaskets, oil change (due to possible contamination) should be done in the process and if you have not yet done thermostat, PCV, water pump, supercharger oil especially at your mileage it really should be done, especially if you are planning to keep the car for awhile!
