This is the FEBI BILSTEIN (36545) contact switch (thermal switch) located in the steering column of the BMW 5 Series E39 (1995-2003), which is the heart of the electrical system. Over time, this part can wear out, causing "ghost faults" such as failure to start, radio shutting off while driving, electric steering not adjusting, or the airbag light turning on. This is a high-quality equivalent to the original part.
- Chronic Problem Solution: Effectively resolves absurd electrical issues commonly seen in E39s, such as "the radio shutting off when the sun visor mirror is opened."
- OEM Quality: Febi Bilstein manufactures to BMW standards, ensuring long-lasting and safe use.
- Easy Replacement: Located on the left side of the steering column, directly behind the ignition key slot. Only this electrical part is replaced without changing the mechanical lock.
- Wide Compatibility: Compatible with all E39 Sedan and Touring models (520i, 523i, 525i, 528i, 530i, 540i, M5).

Frequently Asked Questions (FAQ)
What is the E39 Sun Visor Test? If you have strange electrical issues in your vehicle; lower the sun visor and turn on the light of the makeup mirror. If the radio goes silent, the horn doesn't work, or the steering wheel buttons become inactive at that moment, the thermal switch is faulty. This part will solve the problem.
Will my key need to be changed? No. This part is only the rear section that distributes electricity (switch). The mechanical lock and immobilizer code that you insert the key into will not change; you will continue to use the same key.
The vehicle sometimes doesn't start, the battery is new. Is it because of this? Yes, the copper contacts inside the thermal switch wear out over time, and even if you turn the key, no signal goes to the starter motor. The indicator lights come on, but there is no "click" sound.
