Is it normal for a BMW E90 to fail to start?
2 Answers
It is not normal for a BMW E90 to fail to start, and it requires timely inspection and repair. Here is a detailed introduction about BMW cars: 1. Overview: BMW cars refer to vehicles produced by Bayerische Motoren Werke AG (abbreviated as BMW). The main series models include the 1, 2, 3, 4, 5, 6, 7, and 8 series. BMW is renowned worldwide for producing luxury cars, motorcycles, and high-performance engines. 2. Logo: The BMW logo features a double-circle design with the letters "BMW" inscribed above the double rings. The entire emblem resembles the blue sky, white clouds, and a continuously rotating propeller, symbolizing the company's long history and its consistent purpose and goals.
It's definitely abnormal for a BMW E90 to fail to start. I've encountered similar issues with this model several times before. The most common cause is a weak battery, especially in cold weather. Use a multimeter to check the voltage – if it's below 11.5 volts, the car basically won't start. Next, listen to the starter sound; if it makes a clicking noise but the engine doesn't turn over, it's probably due to worn starter motor brushes. Another common BMW issue is electronic steering column lock failure, which will show a steering wheel icon on the dashboard. I remember one customer's car had a clogged fuel pump filter screen cutting off fuel supply, which required removing the rear seat base to fix. If the dashboard warning lights are flickering randomly, it might be water damage to the CAS module – that's the most troublesome to repair. The older E90 models are already over ten years old, and wiring aging can also cause inexplicable starting failures. I recommend finding a BMW specialist shop for diagnosis as soon as possible.
