Mileage warning for urea tank

How accurate is the mileage warning to refill the urea tank on a 2011 335d? Is it base on the type of driving you're doing?

My warning light came on yesterday while I was on a road trip from Santa Barbara to the Monterey Bay area.

The countdown mileage didn't seem to correspond to the mileage of my commute this morning. I've got a service appointment scheduled for next Tuesday (scheduled prior to tank low warning). I've penciled out the mileage and it will be close.

If I stop by the dealer prior to my service, will they fill it for free?

The dealer may try to charge you for filling it between service. The capacity of the tank and usage of the urea fluid are enough that you should not need refill between service interval (about 13000 miles). Sometime, the urea tank is not fill properly at the port of entry or at the dealer.

If you pay for the dealer to refill the tank, it will cost you a lot more than doing it yourself.

Here in Atlanta, you can get DEF for about $12 for 2.5 gals

depends on dealer. I know mine would do it for free. If you are close to oil change then just add some by yourself and you should be good till oil change. Its very easy to add DEF. If you are not close to oil change your dealer should take responsibility for not filling both tanks and do it for free.

Thanks for the advice. I'm taking my car in for a regular service/oil change next Tuesday. If I don't think I can make it, I'll stop by the dealer later this week. Btw - do you need a special filling nozzle if you buy DEF at an auto parts store?

I bought the BMW bottle and just refill it. It has the nozzle.

My experience is that the easiest/cheapest way to do it is: buy the 1/2 gallon bottle for about $13 at a VW dealership.The DEF *they* sell *is* suitable for BMW,Mercedes,etc.When you've emptied that cut the trimming toward the bottom of the special bottle so that the blue top screws off and back on.Then buy 2.5 or 5 gallon jugs (without special nozzle) for about $5/gallon.Then fill the 1/2 gallon bottle from the larger jugs and voila.Not difficult or time consuming.

Also, my experience has been that the warning is accurate in terms of mileage.
 
#7 ·
Yes, it goes on at 999 miles left, then it won't let you restart the car.

Mine went off just prior to my scheduled service interval so I just cruised in without a problem. I got like 12k or 13k between service intervals.

People who don't drive a lot are going to have problems with this type of car. So many things require engine operating time and/or distance to sort themselves out. The larger of the two urea tanks for example needs heat from the exhaust to make sure the urea is liquid so that it can be pumped into the smaller, electrically heated tank to replenish it. This may not apply to the OP but it should be a warning to people who make only short trips around town as their normal driving pattern (not to mention the DPF burnoff issues that will arise from that as well).

I think you're right.I believe that diesels,in general,are far better suited to highway cruising than to city "stop & go"...or even suburban 30mph driving.Fortunately about 90% of my miles are Interstate miles at 70MPH.I've read,more than a few times,that incomplete DPF burnoffs can cause serious and expensive problems over time.

I think,although I'm far from sure,that there are several "safety" measures built into the system to ensure that ample warning is given before you have a "no start" situation.IIRC one of these measures is that you get one more start *after* you get to zero in order,I assume,to get yourself to a place where DEF is available.Also,I think,the vehicle won't stop dead if you reach zero while driving which is also good.I'm almost certain about these two things but not 100% certain.

I don't drive my car much but when I do drive it then it means at least 40 miles before the engine is turned off. Having been through the low DEF warnings I can say someone would have to be blind and death to not notice the alerts and run out of the stuff. The owners manual does detail what happens if you run dry. I thought if you run out that you got one engine start but I could be wrong on that. Also someone could run out of it simply because something is wrong with the system and the alarms mislead them on how long it would last. The stuff is so easy to get though that I find it hard to believe anyone would get to a no start scenario. I was at six auto parts stores this past weekend and they all had DEF up by their front counters and for cheap.

I rolled into the dealer for my regular service today with about 250 miles to spare. They filled the urea tank, changed the oil, did a full inspection and installed some new wiper blades per my request.

I'll probably jinx it, but I have to say my 335d has been flawless so far. I bought the car with 15K miles on it and now has 24K miles. My commute is about 70 freeway miles round trip each day during the week, so I'm loving the great mileage combined with the performance.
 
#16 ·
Bayou, why would you roll in with 1500 miles to spare?:dunno:

BMW won't service the car prior to being due, except for the DEF if you have the warning light, and that has been debated by some dealers.

BMW policy is to service the vehicle on request if it is within 2,000 miles of the indicated service.

I suspect this is because of the limited number of BMW dealers in the US, e.g., none at all in Montana or North Dakota. When I take a trip to the West for camping, I often drive 700 miles a day. Getting to a dealer close to the indicated service mileage would be a real inconvenience without their 2K policy. I hesitated to mention this on the forum, as if everyone brought their vehicle in for service 2,000 miles before it is due they might decide to change the policy.

Flying,

When I contacted my CA this morning regarding milage warning & I told him my vehicle still had 1500 miles til next oil change. He offerred to kill 2 birds with 1 stone. Since this will save me another trip to the dealership, I didn't bother to suggest otherwise.

God only knows what BMW is monitoring with these cars. The dealer that I bought my car car from called me to schedule a service appointment a couple of days before my car told me it was due (guessing that there's some transmission to the Mothership). The mileage was at something like 1,400 miles until the service was due. Since this was my first service, I wasn't even thinking about the urea tank, so I pushed the service out until after the Holidays. Next time I'll go in sooner than later. ;-)

If you have BMW Assist, the car has a GPS and cell phone built-in. The car reports service needs to BMWNA, which routes the info to the dealer. They seem to get notified early (>1000 miles).

Annual free maint vs mileage based free maint

1-4-13, my 335d is due for its annual free oil change maint nominally 15,000miles but my mileage is half that at 6,500, several dealers have argued that BMW NA will not reimburse them so don't want to honor the 50k 4 year free maint program. These dealer opinions are based on the opinion of a so called warranty clerk that who typically is some young female that rough tough mech types listen too. I have no such addictions to nor am I that easily led by the nose so its Been a real struggle to get the service that is due my 2011 BMW 335d. At this point I wish I never heard of bmw or been influenced to buy, by the free maint program...there is a real disconnect between BMW and its dealers and customers covering this program...Plus the lying going on at every level I.e. the sales manager of one big dealer told me his son has had no issue with his diesel and it has a similar mileage and time issue. Of course I mentioned maybe its the bosses son which generated his free service. I hinted around that I thought he was exaggerating beyond my capability of believing his story. I am so tired of sitting in a dealership manger office repeatedly asking them to show me in writing where the diesel is exempted from the free service under all circumstances, the gas engines do get the servive though... They tell me. my 335d is due for its annual maint but not enough mileage to qualify according to the dealers how is one suppose to plan to use exactly the mileage required at the exact time require. Finding more cooperative dealer seems at this point impossible. Needless to say every time I read on this blog of someone who had no trouble with getting this free service including the many posts that claim they also got additional services including free windshield wipers or free brake pads stretches the imaginations of skeptics like me, I don't get it what's to be gained by bragging of all free stuff you got from BMW when we all know or should know it a pack of lies. It's just sad. Americans forgot how to tell the truth at all levels..
 
#33 ·
sorry you're having problems but having owned several BMWs over the last decade and a half, I have never had a problem getting the maint. done including things such as brake pads when needed without any cost to me. so either find a better dealer or sell your car and go to another brand but please dont call the rest of us liars just because you are having a bad experience.

I have had zero trouble getting my annual low mileage oil changes. But my cars computer had always said it was time for an oil change. I think in the past year they changed the length of time on oil changes. Meaning this month or next when I get around to pulling my car out of storage for its oil change that I thinking the computer will have a much later date than Jan-2014. Bottom line though if your car says it is time for an oil change then you need to find a different dealer but if your car is not saying time for an oil change then good luck with arguing with the dealerships. Also in the three years of ownership none of my oil changes had a 15k mile interval, I think it was 13k.
