Genuine Audi (GUS052910A3) Diesel Exhaust Fluid

Great value for the money. I bought another type that was smaller because I wanted a way to easily fill the car with fluid without a mess. I use this product to refill those smaller bottles and it allows me to keep some in the car for when it starts to get low. This is quality fluid for my VW TDi. Size of bottle is not great for filling direct into my car. So the ease of use is not that great. Thats why I refill another small bottle or two.

Worked fine. Cleared my alarm.

Not rating the product, rather the service. The vendor has upgraded from shipping via USPS to UPS. I observed a huge improvement! When delivered by USPS, the packaging was so beat-up it seemed a small miracle that product was not leaking. When delivered by UPS, the package was in near mint condition. Thank you Crown, for upgrading your choice of shippers.

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.

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

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

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.
