Genuine Audi (G052910A2) Diesel Exhaust Fluid

The real reason to purchase this over any other DEF, is to get the bottle that it comes in. VW, Audi and other vehicles use a specific fitting on the DEF tank that allows this type of bottle to interface with it. This allows you to add DEF without needing a funnel and it has a handy valve built into the neck of the bottle that gives you the ability to start and stop the flow from the bottle. This container screws onto the VW/Audi DEF tank filler and provides a spill free method to add DEF. SO- After you empty the bottle the first time, you cut the bottom of the bottle off and use it as a DEF tank funnel in the future.

Purchased one of these overpriced DEF containers to use as a funnel in my Range Rover Sport. After I emptied it into my tank the first time, I cut the top off and have since used it as a funnel with PEAK BlueDef to fill my DEF as needed. Works GREAT and saves me lots of money vs those who go to the dealer's service dept for an overpriced fill! (I order the PEAK BlueDef from Amazon in 1 gallon containers for about $4.50/gallon)

I have purchased many different adblue for the Audi, but this is an absolute ingenious design. Such an incredible and simple way are putting this without any spill. I love this kudos to Germain engineering.

Bought this to use with my BMW X5 F15 diesel. Fits perfectly and works perfectly. Even better, the adapter/one way valve comes off easily so you can refill the bottle from bulk containers and save money. Highly recommended.

I bought this item because my previous bottle cap broke and I had no way to fill up my car. So I needed a new bottle (I buy a 5 gal jug of DEF and fill it up as needed).. although I did notice a small design change where in the cap where I had to cut the strap in order to refill the bottle. Other than that I had no issues.

This bottle works great as advertised. But I drove mt 2013 Passat up to my local gas station that has DEF at the pump to try it. I worked just like putting fuel in an automobile, and it was only $2.79 a gallon. wish I try the pump before I paid $18 for this half gallon

No issue with the product but what it was send in. VW offers an adapter as the bottle pictured on this site has been discontinued. Seller is doing a bait and switch for a product more expensive than what the dealer charges. Buy the adapter, not the bottle. Don’t buy from this seller.

Simple and toolless, takes a couple minutes and fills up your tank without issue. It does take awhile to arrive though, I'm guessing it ships from Europe. It took me ~3 weeks to arrive.
