What is the reason for the BMW 5 Series electronic gear shift not lighting up?
2 Answers
If the BMW 5 Series electronic gear shift is not lighting up, it is necessary to check whether the gear shift is functioning normally. If the gear shift is normal, the issue may be due to internal damage to the gear position switch. If the gear shift is not functioning properly, the problem could be related to wiring or the control module. The domestic 5 Series is a high-end sedan, a product of the German BMW company, classified as a mid-size car. In terms of body dimensions, the BMW 5 Series has a length, width, and height of 4998mm, 1901mm, and 1559mm respectively, with a wheelbase of 3108mm. The powertrain of the BMW 5 Series has been further enhanced, with the top version 545i equipped with a V8 engine from the 7 Series, delivering a maximum power of 245 kW and a maximum torque of 450 Nm, accelerating from 0 to 100 km/h in just 5.9 seconds.
My BMW 5 Series electronic gear selector once had an issue where the backlight wasn't working. It turned out to be a blown fuse located in the small compartment below the glove box on the passenger side - just check the manual for reference. If the fuse is fine, it could be a wiring short circuit or loose connection. BMW's electronic systems are quite sensitive and prone to malfunctions when voltage fluctuates. I tried restarting the car by turning off the engine and waiting a few minutes before restarting, but that didn't help. I recommend first checking the battery status, as low voltage can cause the gear selector light to fail. Functionally, the gear selector works normally, but driving with an unlit selector is dangerous, especially on highways at night - mis-shifting could have serious consequences. During routine maintenance, ask the shop to scan the electrical system to prevent such minor issues. DIY repairs carry significant risks; don't randomly replace parts to avoid damaging modules through improper operation, as delaying repairs often leads to higher costs.
