And yes it is true, they did change the DEF service procedure to top it off now...

Wow, so you could go 4 years without a DEF flush?

if you fail to trip 6000 miles per year, you will go 2 years to the first oilservice, and only get a top off.

Can they retroactively change the service requirements for a car already purchased with a documented warranty plan? Hmmm.

Sure they can, as long as they don't deny warranty claims on the DEF injection system for failure to do a flush.

I think they were overly nervous on the fluid shelf life when the vehicle was introduced, and have since decided that they don't have a significant risk of not meeting the emissions standards due to stale fluid. They should give all you 35d guys bumper stickers that thank you for being beta testers.

I was asking a fairly narrow legal question, not if they can change their policies, but rather if their documented policies as defined in the manual and documents provided at time of sale may be unilaterally altered by one party.

Agreed their DEF plan was probably overly strict.

I briefly chatted with a tech as I was about to drive off (following the oil change.) what he said was the service cycle for def flush has changed according to a bulletin. I have not seen this bulletin. If someone here has a subscription to the BMW site, please upload it so we can see.

Thanks for confirming the DEF service change.

Interestingly BMW NA's new plan is a lot more like the DEF maintenance plan proposed by one of those wacko board members a while back...

"Drive a minimum of 12-15,000 miles a year. Run the DEF down until the warning appears. Fill ONLY the passive tank. After the DEF warning disappears, top up ONLY the passive tank. If the total DEF added is at least 5 gals., leave well enough alone "
