In this video I do another piston soak with B12 Chemtool on an Audi 2.0T - this time in a Q5. The vehicle was burning 1L of oil for every 500km, which is extremely high.
After the piston soak with B12, the vehicle has stopped burning oil and is now well above the manufacturer specifications for oil consumption.
A lot of folks are asking where to source B12 outside of the US. In general Amazon and eBay seem to be good sources for the chemical. For Canada you can also try www.radwell.ca who seem to carry B12 in boxes:

Updates and notes:
1. Users have confirmed this treatment is effective on other cars as well including Volvo, Hyundai, Toyota and Honda
2. Some users have experienced carbon build up on the pistons after the piston soaking process that prevents them from turning the crank over. This has to be cleaned up before you try to use the starter so compressed air and a lot of patience will get you through.
3. Multiple viewers have reported a successful reduction in their oil consumption after a piston soak on 2.0T and 3.0T motors.
4. A user reported multiple misfires as a result of the piston soak. I experienced misfires on both my A4 and Q5 after the hard starts seen in this video. In all three cases, pulling the plugs an cleaning them up has resolved the misfires. It would appear the plugs get fouled due to the excessive burn up of soot immediately after the piston soak. As a result, after draining the dirty oil, I replace all plugs with new ones. The same may be applicable to the injectors although no injector issues have been reported so far.
5. Multiple viewers have asked about alternatives to B12 as it may be hard to source in various parts of the world. Any solvent which is safe for the engine should work fine including diesel, engine flush, Sea Foam etc. B12 appears to be the strongest one but I am sure there are plenty others that can do the same job. I used Sea Foam and STP engine treatments to fix my A4 so they have been tested.
