BMW allowing dealers to re-program start/stop

SI B12 15 12

INFORMATION
The Automatic Start/Stop (MSA) system is a further BMW Efficient Dynamics measure aimed at meeting BMW's commitment to reducing CO2 emissions and enhancing fuel economy.

BMW, always a leader in innovative technology, will be the first automobile manufacturer to bring MSA technology to all new models.

Automatic Start/Stop systems will become prevalent in the future, as manufacturers strive to meet increasingly stringent emissions and fuel economy requirements.

By automatically switching the engine off when the car is stationary, MSA can improve fuel economy and reduce emissions.

New F-vehicles now incorporate the second generation of MSA (MSA II), which has been further developed to operate in combination with an automatic transmission and the BN2020 electrical system.

A detailed description of the MSA Automatic Start/Stop function can be found in the ICP Technician library under Technical Training course ST1112.

SITUATION
Some drivers have expressed the desire to deactivate this function in certain situations. This can be done manually via the Automatic Start/Stop function button with the LED switched on, indicating that the start/stop function is deactivated.

However, by default, the Automatic Start/Stop function is reactivated each time the engine is started.

At the request of an owner, it is possible to modify this default logic to "Last user mode."

With this logic, the current MSA's activated or deactivated setting is stored and used on the next trip.

Note: All new BMW M models have the "Last user mode" as the default setting from production.

Pair of diesels headed for BMW U.S. dealers

BMW first introduced the North American market to diesels way back in 1983, with the introduction of its 524td. Under the hood of the E28 5 Series was the automaker's M21 turbocharged diesel, a 2.4-liter inline-six rated at 115 horsepower and 155 pound-feet of torque. It was mated to a standard four-speed automatic transmission. At the time, BMW claimed it was the world's fastest production diesel-powered car, but its numbers (0-60 in about 12 seconds and a maximum speed of 112 mph) look rather pathetic today. It was sold for just one model year.

In a renewed effort to convince buyers that diesel was a sporty alternative to gasoline, BMW reintroduced a potent diesel powerplant to the States in 2009. It was the automaker's M57 twin-turbocharged 3.0-liter inline-six rated at 265 horsepower and 425 pound-feet of torque. Mounted in the nose of the E90 3 Series sedan and mated to a six-speed automatic, the 335d helped the automaker redefine oil-burning performance (0-60 in 5.3 seconds with a top speed governed to 130 mph) here in America. The X5 35d crossover, fitted with the same engine and strong performance (0-60 in 6.9 seconds), soon followed.

But BMW doesn't really need to prove diesel's performance anymore, as fuel economy sells. With that comes the announcement of two fresh, and more efficient, oil-burning powerplants. A new turbocharged 2.0-liter four-cylinder will likely be rated at 180 horsepower and 280 pound-feet of torque, while a new turbocharged 3.0-liter six-cylinder is expected to make 255 horsepower and undisclosed torque. According to our sources, the 2.0-liter (similar to the one pictured above) will find its home in the 3 Series and X1, while the new 3.0-liter will replace the M57 under the hood of the X3 and X5 (with eight-speed gearboxes). Expect the engines to spread across the BMW lineup if well received.
