Less than 5000 miles ago we had our 335d in for a first maintenance and a refill of the Diesel Exhaust Fluid (AdBlue). So you can imagine our surprise when the warning light appeared on the dash a couple days ago warning us the car had only 1000 miles left before it would no longer start, unless of course we add more exhaust fluid.
We're still in the process of working out the math with the dealer who did the service, since the car should go at least 10,000 (though closer to 15,000 is expected) out of a fillup. We suspect they may have topped up only a portion of the tank since we were early for service. But hey, the light was on, and we had no choice.
With yet another weekend trip to Michigan planned for the young, soon-to-be-wed Mr. Fowle, we decided to fill'er up ourselves this time. A stop at our local BMW dealer (not the one who serviced it, as luck would have it) netted one half-gallon bottle of crystal-clear factory exhaust fluid for the sum of $39.99 plus tax.
Adding the fluid to the car was no problem as you can see below. It's a simple matter of popping the cap on the bumper, removing the two filler caps beneath it, and screwing the no-spill bottle into the lower port until it drains. The whole process took about a minute and a half.

Re: MWerks Project 335d- Topping Up the Diesel Exhaust Fluid (gintaras)

make sure you top off the blinker fluid too, and the muffler bearing.

Believe me, even muttering the phrase "Exhaust Fluid" is like nails on a chalkboard to my ears.

335d has two tanks for the def, one passive and one active, the active is the smaller tank and the passive is larger tank. The active tank where the def fluid that get pump into the exhaust. The kruse bottle only fills the active tank.
BMW maintence only covers items when they are a schedule due. Since this is no scheduled service, he had to pay for it. But since it such a low mileage since you topped it off maybe you might have a faulty sensor in the active or passive tank and throwing the system off. Your driving profile also affects the def fluid

We actually have an appointment tomorrow to double check. The warning light hasn't gone off yet.
