Volkswagen Audi OEM Fuel Additive G001770A2

I've been using this for a few years now in my tuned MK7 GTI at every oil change (5000 miles). I can only assume it keeps the fuel system clean since I have never had any fuel system issues at 57K miles and counting. It is the OEM fuel system cleaner recommended by VW; hence the 5 stars.People should note:1) This will not remove/prevent carbon buildup on most recent Audi/VW Valves since most are TDI (direct injection) which means that the fuel is sprayed directly into the combustion chamber and bypasses the valves.2) I saw several reviews giving poor ratings because the person stated that the additive did not make their car run better. If you have used this product because of a rough-running engine and your engine did not run better after running through a tank of this, you probably have other issues with your car. This product it NOT a cure-all! You most still tune your car and maintain it. Try a new air filter and new plugs to start.I am not a representative of VAG nor am I paid to promote this product. I am just an informes and experienced backyard mechanic (for what that's worth) sending out a PSA.

This product is worth it's weight in gold. We get 300-345 on the Q5 in mileage for a tank if gas, after one use or 1 can, we got 420 miles to a tank, we always use 93 octan gas, but this just blew us away, and the car has 120,000 miles on it, with 2.0 T AWD, just amazed on the fuel increase.

My Audi started idling just a tad rough since the last oil change from 5W-40 to 0W-30 when winter hit. On the warmer days the rough idle seemed to be less annoying than that of the colder days, so I purchased this for my second time to treat my fuel system and wow! I honestly thought my car had cut off at the stoplight in town earlier today, my engine was that quiet. I then drove down the highway for about 30 mins to let it work its way through the fuel system and my mileage was significantly better as well. I've always ran 93 Octane in my car and noticed the turbos run through my tank pretty quick, so to see that change in 30 mins to my usual gas consumption confirms this stuff works and good! Definitely a recommended buy!

the shipment did not include a funnel ... why?

Great product for the carbon buildup in these cars. I drive a 5.2L V10 so having easy and quick access to this additive is amazing. Wicked fast shipping.

I bought this due to the feedback, yet, it didn't work out for me. I have a slight rough ideal and used 2 cans and nothing changed.

I use this for my older Audi and immediately notice improvement! Order ten cans if you love your car. Audi recommends this if you put low quality gas in your car. One can works miracles and wonders for all VW or Audi cars. This is the factory made product they use at the dealership. I even put the last few drops in my lawn mower- suddenly it runs like new.

This is a great product and it gets 5 stars for not being a knockoff! I gambled and ordered 4 at once... I won!! This smooths out engine idle and helps keep the car in good running condition. 1 little bottle covers up to 20 gallons of fuel... Great product!!
