sounds cheap for 2.5gal

Yes, same exact stuff that I used, it is all the same no matter what the brand is.

Same as I used, but I do not like the jug and spout so decanted 1 liter at time to open jar container and then with funnel into reservior, saves spills

Dude, if you need new spark plugs for your diesel, you've got a much bigger problem than low DEF.

They do not pay for maintenance if it is not called for by the CBS. The CBS is defined as the car telling you it needs service. When the car says "I need DEF" this meats the definition of a CBS indicator.

Customers that can verbalize this issue can usually get it covered....

Splitting hairs, but:

• If my car tells me my washer fluid is low, should I expect BMW to pay?
• If my car tells me my oil is low, should I expect BMW to top it off for free? (The X5's been great in this regard, but I always had a spare litre of oil in the M3).
• If my car tells me I will run out of diesel in 32 miles ... (You get the drift).

DEF is a consumable fluid, so I'm not sure why it should be any different than the other fluids we consume every day ... UNLESS it is considered part of the emissions system. I think that's where I would make my argument.

Splitting hairs is the point, no?

BMW **does** cover DEF under the maintenance plan, hence by their own definition it is a covered maintenance item. (This addresses the washer fluid and diesel fuel arguments, which are NEVER covered).

BMW then seeks to exclude DEF outside of a normal oil change visit by using the same legal boilerplate that they had used to exclude interstitial oil services...the problem is that this language is not applicable to the DEF warning. If you read the actual text, your probably say "Huh, that sure is weird...ard is right"..Maybe

On the Oil (should they give you oil if the CBS says "Add oil"), the answer is 'yes'. And I think that BMW WILL in fact top off your oil when low.

But as we both can probably agree, going to the dealer for oil OR DEF top offs is a waste of our time.

Just did mine today. Bought three 2.5 gallon jugs at Fleetfarm for $12.99 each. Filled the passive tank first, took just under five gallons. Filled active tank last, took just about 3/4 gallon. Done in 15 minutes including wiping everything down to avoid the dreaded white stains. Very simple with a basic funnel. Will have oil changed in next month to complete the cycle. Very easy to do. As simple as adding washer fluid.
