Genuine Audi (GUS052910A3) Diesel Exhaust Fluid

When you don’t have access to a synthetic horse ranch. Nothing compares to pasture raised, hay fed, synthetic horse urine. Your VW/Audi TDI deserves nothing less than the best. 10 out of 10 will purchase this again

It worked the same on my 2014 A6 TDI. No lights showed up on the dashboard so it's legit. If you're thinking of buying 5-6 small bottles to go through the year just get 2 or 3 of these, it's cheaper.

Used for 2015 VW Passat TDI and was enough to turn off def warning. I used a screw on flexible hose to add this to the car's def tank. Dont see any dates on the bottle if thats a concern for anyone.

Much cheaper to buy the big bottle than the small ones. Of course, you lose the screw-in nozzle, but a $4 offset funnel from Amazon and just paying attention when you fill up the DEF and you're in at like 25% of the cost.

Didn't come with the screw on spout so now I have to buy another somewhere to get the spout so I can pour it in without making a mess, not worth the hassle

Good price, so far no issue with product, just wish it had a spout with it.

I added this about a month ago. The light went away and my Q7 continues to run great. No issues. It is from VW/Audi, not aftermarket. If you're adding to a Q7 it takes 24 liters or 6 gallons. So you will need 3 of these to go from empty to full, but 2 will get you over 5,000 miles.

Pro tip, order the one liter bottle that locks in, dump it in, cut the back out and make a funnel out of it. Use this stuff to refill.Your welcome
