I typically see mid 30s for highway MPGs in my 2014 535dX due to my heavy right foot. I have achieved over 40 MPG in the past but not very often. I'm not into hypermiling.
Agreed. Not sure what Tomo was implying
Which driving mode do you typically employ? I use Eco Power most of the time.I typically see mid 30s for highway MPGs in my 2014 535dX due to my heavy right foot. I have achieved over 40 MPG in the past but not very often. I'm not into hypermiling.
I'm only at 107k miles on the 535dX and climbing. My 2012 X5 35d is only at 194k miles and climbing.
I'll try it.. but I thought that it then changes it from ECO to Normal mode since its not true ECO mode. I'll try it tonight and let you know.
It remains in Eco mode, with the gearing and acceleration altered, but just disables the auto shut off when you stop the car. We have the same year & vehicle so I'm certain yours will work the same- unless your chip tune changes that.
. Based on the dashboard display of our 328d, we're averaging 6.2 liters per 100 kilometers, which translates to just over 45 miles per imperial gallon. Sorry, I don't have a calculator for the smaller US gallon. We've noticed that the consumption has improved with the change from winter to summer tires, and as the mileage on the car has increased (maybe the engine continues to break in?). Very satisfied with this car, and we're not hypermilers. We tend to leave the car in "Confort" mode, and typically have the A/C on.sounds like a nice car, congrats!Canada here
Happy Campers here!!
There has been discussion here and other fourms that state that coasting in gear with modern diesels actually cuts the fuel and uses momentum to keep the engine rotating.
Your are correct and YES your ALH does this. Fueling goes to zero whenever the engine is in an over-run condition such as decelerating in gear. You can verify this by looking at data from VCDS. BMWs do this too.
Why use ECO mode at all? It sort of defeats the purpose of driving a BMW. I don't like the other things that ECO mode does such as de-power the A/C. You'll notice reduced A/C performance in hot weather while in ECO mode. I have only used ECO mode in my 535dX enough to verify that it works and explore its behavior. The engine shutting off at a stop in traffic was a bit unnerving the first time it happened. I keep the auto-stop disabled at all times. I don't drive my diesels for MPGs and the better MPGs comes as a bonus.

I'm averaging low 30s with my heavy right foot in my 535dX. I drive exclusively in Sport mode. Sport mode gives a smarter shift strategy for spirited driving and automatically downshifts when decelerating. I like Sport mode better for in town and city stop and go traffic. I find it has tighter control over what the car is doing, like what you want with a manual transmission.
BMWs like TDIs need to be driven hard and like they were stolen to help prevent intake clogging (aka carbon buildup or CBU in the Bimmerfest forums). Also avoid using them exclusively for short trips. Driving in Sport mode helps keep the RPMs higher to avoid CBU problems due to low-RPM driving. Just like with TDIs, "drive it like you stole it" applies.
Food for thought, the M57 engine is used in both 335d and x5d. The x5d is heavier and has secondary, low pressure, egr. The 335d tends to build up CBU a lot faster than an x5d, with many x5's att 100+K miles and only minor build-up, yet my 335d was all caked up at 47k miles. Deleted the EGR and there is now zero buildup, just oil residue from CCV. I don't think fuel quality or additives have anything to do with CBU. Soot coming from EGR and oil from CCV combine to create that nasty tar-like substance.
I kept my 2011 335d for over 100,000 miles and only had a problem with the urea injection thermostat (with what ended up as burned out catalytic converters after using a diesel preserving additive at around 25,000 miles BTW). No perceived CBU in any of my direct injection diesels with all going at least 100,000 miles. Of note, the engine management software was upgraded about 2-3 times just during the 2011 model year.
Was this on a North American 335d? If so, not debating, but getting to 100K without a CBU cleaning is a rare feat. If the car is dedicated to highway commuting, I've seen this, but in general with a 60hwy/40%city driving mix most are choked up by 70k miles and unless it’s started to foul up the injectors, most don’t notice the loss of power. We've literally seen hundreds of manifolds and intake runners caked up with CBU on the NA e90post forum or facebook group. No additive will eliminate soot. The NA specific EGR system is a crappy design, euro models tend to fare better.
Sorry but your figures are from BMW? As a mechanic that only sees problem cars? From reading posts on the Internet (how many owners don't post?)
My figures (yes estimates) come from the sources I already quoted to you. The e90post M57 owners forum and North American BMW Diesel Owners Group (NABDOG) on Facebook (1,974 members as of today, primarily M57 owners) can attest. Countless members, in stock form, posting their CBU experience. The other issue you are overlooking is that even the slightest boost leak (red charge pipe is notorious and common for being leaky) can create significant amounts of soot, not register as a fault, and when mixed with oil vapor from CCV just creates havoc in the manifold. There were only 10k or so 335ds imported into NA. Go ahead and google 335d CBU as see how many threads there are to support what I'm saying, including my personal experience. I can remove my manifold in about 30mins and had it off regularly. It's a common problem. (here is a link to just one thread with hundreds of posts discussing their CBU cleaning experience) http://www.e90post.com/forums/showthread.php?t=1058497
Gold color, pretty clean? I recall seeing one for sale recently in CA and if that the car, nice pick-up
