For the Diesel Fanatics...
Hi to all XBimmers:
Came upon this on another forum - the 2 PDF files make for compelling reading - seems to be from BMW Tech Training Manual: http://www.bimmerfest.com/forums/sho...72#post6171172 Also - new M3 seems set for I6 after all: http://www.caradvice.com.au/174031/n...six-confirmed/ (some interesting Aussie comments as well...) |

Bit of a weird review that, very negative towards the diesels.
I've always driven diesels just ordered an X3 M Sport. Just two simple things you have to do, wait until the glow plugs go out (in the Summer virtually straight away, the Winter a couple of Seconds). Then fill it up at any station with any type of diesel other than that no run in periods, no worrying about consistency of the fuel etc etc. Good MPG and loads more torque than the equivalent petrol model normally. Very happy |

I drive the 30d and there are no glow waiting. Apparently it finishes the glowing when you open the door. Just push the button and go. Works in -15C as well |

I assume you use any diesel fuel. Personally I use a premium diesel in my 330d. Like many other BMW users, find I have better performance, smoother running, quieter engine and better mpg. High performance diesel engines will typically give cleaner running, less smoke and better combustion, if we run with a higher cetane rating and better additive package in the fuel we use. Some of the benefits may only show up long term, when items like the EGR valve and inlet manifold/ports will have less carbon build up, and items like injectors should give a longer service life.

Pay attention to "special" Diesel, there are many cases of dealers/mechanics who discourage continuous usage of such fuel. The doubts are on the less lubricant properties of such special Diesels.

Hi All
Three month old X3 done 21,000km of open road, not city, touring. Service yesterday advised that the particulate filter was nearly blocked!! Not warranty job as it must be the drivers fault!!! It appears that the regeneration system has failed but it is my fault. I was under the illusion that long open road trips were ideal for diesels. Will keep the list informed of this issue but it is looking like I could had bought a big petrol and it would have cost less for fuel than the diesel plus cost of replacing particulate filter!! KF |

One may have just been in a sh1tty mood. The next might be more reasonable. One of the 1 series guys had a tow hook cover fall off while on a club drive. The first dealer he went to said no way to a warranty claim. The second replaced it without question.

Glow plugs heat the inside the cylinder so that diesel will properly burn when the engine is started. This is needed to allow the engine to produce less emissions on startup. If you've ever seen a large diesel truck or tractor startup the dark/blue smoke is usually because the cylinder is cold.
There are no spark plugs in diesel engines. The fuel is ignited spontaneously when it is put under pressure. |

If so, that is a slightly different than using premium fuels such as BP Ultimate Diesel, which includes a lubricity additive. Fuels like the BP Ultimate have been formulated with high performance diesels in mind and endorsed by companies such as Ford. HighlandPete |
