BMW has extended the warranty on the high-pressure fuel pump for the 2012 X5 M and X6 M models with the S63 engine. The warranty covers the pump for 10 years or 120,000 miles. BMW is not recalling the pump and no reason was given for the extension of the warranty.
A DCT transmission uses the gearing principles of a manual transmission.
The phrase “dual-clutch transmission” or DCT can strike terror in the heart of some BMW engineers and technicians. You will probably never deal with the internals of a DCT transmission like the gears, synchronizers and shafts. You will instead have to repair the external components that control the clutches and cool the fluid. But, understanding how the gears and shafts work together is essential.
Fasteners act much the same as a spring due to the physics of stretch and rebound.
Customers generally look to superchargers for the instant throttle response, not fuel economy.
Variable-length intake runners change the length of the intake passages depending on engine speed and load.
Before removing the driveshaft, check for play in the yoke and slip joint. If the u-joints are failing, you should be able to see movement in the shaft as you apply leverage.
The issue is likely because the connection between the LED module & light tube inside.
The transfer case is a rather unique design in the way that it operates a clutch pack mechanically, not hydraulically.
The measurement of voltage is like the speed of the traffic.
Diagnosing the problem comes down to understanding what causes a loss of fuel pressure.
