328d owners: Can you measure def fluid level?
I've got a new 328d diesel. Great car. My question deals with the ability to measure the level of diesel emission fluid (def) - - much the same way as you can measure the oil level whenever you want.
I was under the impression that the def lasts as long as the factory oil change interval (about 10k miles on the 2014's) and that the fluid need only be replaced or refilled by the dealer at the regular oil service intervals. But I read in the Owner's Manual that the def may need to be replaced once between regular service appointments - - and if you drive in a "sporty" style, the owner may need to replenish the def more often than that. No big problem. The Owner's Manual indicates it is possible to measure the def level using the iDrive Control Display as follows: select "Vehicle info", "Vehicle status", "Diesel exhaust fluid". Well, I tried that on my 328d and there is no entry or selection for Diesel exhaust fluid under Vehicle status. Any other 328d owners out there have the same problem, or is there another way to measure the def level? By the way, I have a recent production 328d (October 2013).

I haven't seen it either, but I didn't see it in the manual either. It does give you a warning you need to add some. How much time you have after the warning??

1) The 328d being discussed is the US/CA model, which is actually a 320d in EU.
2) Requirement for DEF varies depending upon engine size, vehicle weight & mileage and grams/mile (km) of NOx pollutants. 3) New models in EU of 320d probably do in 2014 (very soon!). Not sure about smaller engines. |

According to the Owner's Manual: Refill quantity when the 1k mile warning appears is 3 gallons.

I have to fill just under 15L when the warning comes on.

Don’t feel bad... I just did the same filling from a 2.5 gallon jug of blue def. lol. Luckily it was In the driveway, so Half a gallon of distilled water as a rinse (after closing cap) took care of clean up.
