Possible Passive Tank Issue (Urea)

Just got my oil change, fuel fuel filter change and urea refill at a buddy's shop tonight. The active tank filled up nicely but the passive tank took very little urea in, if any at all. We tried several times with no luck. Since he's a certified BMW tech, he hooked up his computer to my car and the software showed my active tank full and my passive tank at "49" which fell under the "low/empty" category.

He thinks it might be a clogged valve. I have no real urgency to look into this right now as I can't deal with the hassle of loaners from the dealer. He's looking to see if warranty will cover it and I'll go from there.

Anyone else encountered this yet?

Anything to do with emissions has a 7/70k warranty on it. You're fine if there's something wrong.

The vent has a tendency to become clogged. Lower the tank assembly and clean the vent of the dried urea.

Worst case scenario is that the tank would need to be replaced

What is the mileage on the car now?
If it is the vent clogged, I wonder how involved is it to get it cleaned out again...

Sorry. Meant to say a clogged vent. Car has 31,000 kms on it and parts of the exhaust would need to be lowered in order to get to the urea tank area.

I'd say 2-3 hours of work.

The unit has some good logic behind it... the 3 level indicators "full" "warning" and "empty" and when ive filled my urea ive had one tank take not a lot. For whatever reason im not sure but drive for awhile and see what happens. it might transfer more. Drive uphill too after filling the tank that will let the car know to indicate another tank evaluation (or sloshing as they call it)

Any details on this procedure? is this a DIY or dealership work?

Thanks 82,000 miles on mine
