bimmerace Private First Class  53Rep 176Posts Drives: F30 335i xDrive M-Sport Join Date: Apr 2016 Location: East iTrader: (0) | Which one, the X5 35D vs X5 35i? I can't decide which one to go for, any input on reliability & power on these 2 engines? All info is much appreciated! More specifically, the M57N2 (M57D30TU2) vs the N55. I already have the N55 F30 and love the engine, and have also drive an X5 loaner with it. Thanks! |

I love the N55 on my F30, but was looking at the diesel for extra mileage and torque, just wasn't sure if it's as reliable as the N55 |

Gave me around 36 on a long drive to Texas about a month ago, also burned some rubber on a launch control! Gotta say, going from 9k altitude to 700ft makes a huge difference even on boosted vehicles! |

Started by test driving a 35i, then a 35d(bought that for my wife), then tested a 50i and almost bought it and now I just test drove an X5M yesterday that I may be purchasing if the dealer can get it cleaned up. The X5 50i is quick, but the X5M... My oh my it's fun to drive! __________________ 2013 X5M 2011 X5 35D Sport Package 2002 M3 2019 i3 |

leo_du_garde Private   29Rep 52Posts Drives: X5, 335d, 335i Join Date: Aug 2011 Location: Annapolis, Maryland iTrader: (0) | We have two diesels. X5d with 110k miles and a 335d with close to 150k miles. Knock on wood, both have been remarkably reliable and still run like brand new cars. No mods whatsoever. Regular maintenance with oil changes every 6.5k ish. Periodically a sensor or emissions related component needs replacement. But the cars never left us hanging. Their engines just purr along no matter what the conditions are. Maintenance cost in line with other non-diesel cars I have owned. I do recommend having a really good BMW tech who knows diesels and knows your cars. Makes all the difference. |

cooticooti16 Private First Class  45Rep 168Posts Drives: Lexus Join Date: Apr 2015 Location: Central NJ iTrader: (0) | I'm all about diesels now. My 535d was incredibly smooth and had double the mileage of my previous E90 6 cylinder. Less overall issues and instant torque. I never bothered with modding the engine and still achieve 38-41 mpg. 600 miles easily on a tank. The diesel grunt isnt for everyone, but I didn't buy the car for anyone but myself. My wife LOVED it as well. If it weren't for the lack of interior space for hauling 4 kids, I would have bought the X535d. Choose wisely! Once the kids are out of car seats I'm most certainly picking up another! |

| Spyro235 Captain 328Rep 788Posts Drives: '10 X5D, '08 e90 M3 6mt Join Date: Jan 2017 Location: CO iTrader: (0) | Hey- I thought I'd chime in, as I just got a killer deal on a 2010 x5 35d. I freaking love it- I get 28+ on the highway, it's super comfortable, and has the beans to get out of it's own way when you ask it to. I just bought it with 204k on it, a week and a day ago, and I've already done 1600 miles. It'll do 600 miles to a tank on the highway and still have some fuel left to play with. As far as I've read, the emissions systems are the main culprits of failure. Mine's got a failed level sensor in a dpf tank, but I'll be able to fix that when I have the time to mess with it. From what I've read, they're really reliable, with none of the carbon build up issues the 335d has. Mine runs like brand new with this many miles on it, and I commute 100 miles a day in it. Worst case, if a major emissions system problem arises, I'll delete it all, and have it properly tuned. That'll get me better mpg, along with a boost in power, and an even more reliable setup. The M57 is FAR less prone to failure than the N57. __________________ Daily/ Tow: 2010 X5 35D - 340k, Deleted w/DUDMD Stage 2, Sutphin Trans tune, Comfort seat retrofit Fun car: 2008 e90 M3- 6mt, slicktop, AW, cloth   |

Regarding mileage, my x5d gets 23 mpg on the highway at 75 mph. Because the 35i has the 8 speed, it can also get 23 at 75 mph. In suburban driving the 35i will drop lower but the 35d will stay the same. My family owns both. The people getting 25+ mpg are going 55 mph. |

I think you ought to check your coolant temperatures, and you'll find they never reach the 88C required to open the thermostat. The most common cause of poor gas mileage on the 35d is a fialed (stuck open) thermostat, which happened to me jsut yesterday. Drove 150 miles, getting 27-28 mpg at 75, and then during the last 50 miles (I had reset by mpg counter and all trip computers) I started getting 22.8. Immediately started monitoring my coolant temps, and they never went over 66C. Highway, or around town. Check it! Over the last 1500 miles, I've averaged 26.5 mpg, that's calculated with fuelly, not on the gauge. My commute is 100 miles round trip on the highway, and pure highway on my way home from picking it up was 28.6mpg. This thing get better milage than my 335i, on the same roads and in the same conditions. __________________ Daily/ Tow: 2010 X5 35D - 340k, Deleted w/DUDMD Stage 2, Sutphin Trans tune, Comfort seat retrofit Fun car: 2008 e90 M3- 6mt, slicktop, AW, cloth |
