BMW M5 Brake Light Switch Guide: 2000-2020 Models
A failing brake light switch in your M5 can cause more than just lighting problems; here’s how to choose the right replacement.
- A bad brake light switch causes multiple issues, including no-start conditions and getting stuck in park, not just brake light failure.
- Replacement is simple and can be done by a DIYer in under an hour, making it a cost-effective repair.
- It is essential to verify the correct part number for your M5's generation (E39, E60, F10, F90) as they are not interchangeable.
- Driving with a faulty switch is extremely dangerous; replace it immediately if you confirm your brake lights are not working.
The Unseen Importance of Your M5's Brake Light Switch
A faulty brake light switch on a BMW M5 is a common issue that can cause a surprising number of problems. Because this small sensor communicates with multiple vehicle systems, its failure can mimic other, more serious issues. Symptoms can appear suddenly and range from a minor annoyance to leaving you unable to start your car or shift out of park. Understanding these symptoms is key to a quick and accurate diagnosis.
Symptoms of a Failing Brake Light Switch
- Brake Lights Don't Work or Stay On: The most obvious sign is your brake lights not illuminating when you press the pedal, or staying on constantly and draining your battery.
- Inability to Shift from Park: Many automatic BMWs have a shift interlock that requires a brake signal to move the shifter out of Park. A bad switch can leave you stranded.
- Car Won't Start: For M5 models with push-button ignition, the system needs to see a brake signal to start the engine. If the switch is bad, the car won't crank.
- ABS/DSC Warning Lights: The stability and traction control systems rely on the brake signal to function correctly. A faulty switch can trigger warning lights on your dashboard.
- Cruise Control Malfunction: Cruise control will not engage or will disengage unexpectedly if it receives an incorrect signal from the brake switch.
Choosing the Right Aftermarket Brake Light Switch
While an OEM switch from BMW is always an option, several reputable aftermarket brands offer quality replacements at a lower cost. Given the straightforward nature of this part, a quality aftermarket switch is a reliable choice.
- Tier 1 (High-Quality Aftermarket): Brands like Hella and Febi are often suppliers of original equipment for German automakers or are known for producing parts that meet or exceed OEM standards. They are a dependable choice for a long-lasting repair.
- Tier 2 (Standard Aftermarket): Brands such as Vemo, Facet, and Standard Ignition offer a good balance of quality and value. They are a popular choice for DIY repairs and are widely available.
- Tier 3 (Economy): Other brands like True Tech and Rostra Powertrain may offer the lowest price point, but it's important to verify fitment and warranty information before purchasing.
Pro Tip: The brake light switch design changed across M5 generations. Always confirm the part number fits your specific vehicle year (E39, E60, F10, or F90) before ordering. Using the wrong switch can result in immediate failure or incorrect operation.

Frequently Asked Questions
Can I replace the brake light switch myself?
Yes, this is a very DIY-friendly job. The switch is located above the brake pedal. Access usually requires removing a plastic trim panel under the dashboard. The switch itself typically unplugs and either twists out or is released by pressing clips. The entire job can usually be done in under an hour with basic hand tools.
Are there any recalls for the M5 brake light switch?
No, there are no specific NHTSA recalls for the brake light switch on any 2000-2020 BMW M5 models. While there are recalls for other brake system components on newer BMWs, they do not pertain to this switch.
Is the brake light switch the same for all M5 generations?
No. The part number is different for various generations. For example, part number 61316967601 is common for the E39 and E60 M5. Later F10 and F90 models use different parts, such as 61319240076 or its successor. It is critical to buy the switch that corresponds to your vehicle's specific year and model.
Is this the same as the 'Parking Brake Switch'?
No. The brake light switch is mounted on the brake pedal assembly. On later M5 models (F10 and newer), the 'Parking Brake Switch' is the electronic button on the center console that operates the parking brake. They are two separate parts with different functions.
