BMW recalls diesel X5 models over fuel filter heater

BMW has announced that it is recalling 1,540 examples of its 2009 and 2010 X5 xDrive35d crossovers produced between June 13, 2009 and November 9, 2009.
According to the National Highway Traffic Safety Administration, the model's fuel filter heater, which warms up the diesel fuel at low outside temperatures, can experience an electrical overload condition that may cause it to become permanently activated. This means the fuel filter heater could remain activated even when the ignition is off, which could lead to a dead battery. It could also lead to overheating, possibly resulting in a fire.

BMW 1 Series getting a small nose job

As BMW prepares to launch its new 2 Series lineup, it appears that the current 1 Series is going to get a little attention for itself. Based on these spy photos, the 1 Series hatchback (F20/F21), which is not offered in the US, will be getting a minor facelift in the near future.
From what we can see in these images, the updated 1 Series will definitely be getting a tweaked front end, with most of the attention focusing on the air intakes and grille. Our shooter tells us that it is possible that the headlights may yet be reworked in some way by the time we see this car in production form. It still isn't clear if we'll ever see this bodystyle or the next-gen 1 Series in the US, but our most recent report seems to indicate that the car's fortunes will depend somewhat on how well the Mercedes CLA-Class and Audi A3 sell.

BMW reveals M4 safety car with innovating water injection system [w/video]

Racing series don't just pick their safety cars at random, or use just whatever car is lying around. These days the car that sets the pace at the front of the pack is typically provided through consideration by a sponsor. In the MotoGP series, that's BMW and its M division, which have served up the Official Car of MotoGP since 1999. What you're looking at is the latest, and it packs some innovative technology on board. Aside from the matte black wrap with BMW's iconic striped livery, upgraded aero kit, retrofitted interior and emergency equipment, this BMW M4 coupe packs a new injection system under the hood. Only instead of injecting fuel, it injects water into the combustion chamber – something that wouldn't usually be recommended, but BMW insists actually aids in the combustion process. The idea is that the temperature of the air being mixed with the fuel inside the engine is usually hotter than ideal, so the system injects a fine mist of water into the collector in order to reduce the air's temperature... sort of like one of those hydrating misters at an amusement park or outdoor mall, but in an even hotter environment. The system brings the temperature of the air down to a more optimal temperature, helping it combust better. The process is said to yield a number of positive effects. For one, it reduces knocking. For another, it can make more out of lower-octane fuel where higher octane isn't available. It also can control the adverse effects of higher ambient temperature on the combustion process. But most of all, it increases output and reduce fuel consumption by around eight percent. Whether that eight percent is worth the added weight of the system – particularly with water pump and a 1.3-gallon tank in the trunk – is up for debate. But we'd imagine that the Bavarian engineers have weighed very carefully. Of course there's also the matter of refilling the water tank, which BMW says would be carried out whenever the safety car is refueled, but in real-world conditions would only necessitate attention once every five top-ups at the gas station. By now you might have guessed that BMW probably didn't develop this system just for the MotoGP safety car, and isn't planning on keeping it confined to the racetrack. Instead it's being tested and demonstrated on the safety car before being rolled out on production models in the future.
