Bmw X5 002F44 fault code

Connect the disconnected vacuum control line, start the vehicle, and measure the vacuum pressure from the vacuum accumulator to the electro-pneumatic pressure converter again. The pressure can reach -95 kPa immediately.

At this time, when the engine is started or extinguished, it can be observed that the control shaft of the wastegate valve moves greatly, driving the wastegate valve to close or open. Finally, carry out a road test and read the engine supercharged data stream. The pressure behind the throttle, the boost pressure before the throttle and the standard pressure before the throttle are basically the same. Troubleshooting.
