So when I pick up my Passat and the dealer tells me the DEF tank is full how do I tell?
There is no dipstick. You just have to add until no more fluid goes in. Also, Adblue is included for 3/36k. There might be a measuring block through VCDS software that can see this through a sensor but there's no gauge or anything like that.
With VCDS, I believe you can find the level (expressed as a percentage) in Engine -> Advanced Measuring Values -> 98-0:Sensor for reducing agent fill level. My Passat with about 3600 miles, mostly around town, shows a fill level of 77.03 %.
Thanks for posting! This is my first VW so I have no idea what VCDS is. Thanks!
Oh, ok. Thanks.
I haven't looked at the DEF tank yet but does it have a long neck, i.e. > 10" or so? If not, I imagine you could put a clean stick in there and see where it comes back. Your own personal dipstick.
I think that there is a light that will come on in the dash when the level is low reminding you to refill.
And in a Mercedes AdBlue car, if you ignore the warning and the AdBlue runs out, you have something like 20 starts, and then your ride goes dead until a refill/reset is done.
I read a post on vortex about a B7 that wouldn't start turns out he was out of adblue. So that is confirmed for us.
I guess one could make their own dipstick and monitor the level. Does this have a long neck going down into the tank or a relatively short neck?
Haven't found anything about how to check the level but it gives you about 1,500 miles warning before it won't start again. My 2012 SEL has 20K on it now and adblue warning came on at about 15,500 miles.
I paid to have my 40k and 50k service done with a package. Adblue was topped off at 40k and I just had my 50k done. Just checked and 39.79% with VCDS
So I used the MB 2.5 Gal with new hose I bought some time ago. Nothing spilled and I kept refreshing the reading with VCDS and got it to 100%. Not sure how accurate it
is, but I have no problem topping off since service is going to be done by me going forward (did 30k too) and Adblue consumption could go up with the "fix" anyway
Your AdBlue tank is 1/3rd full.
