9. What is the meaning of “looped trough” related to BMW brake pad wear sensor?

“Looped through” typically means the brake pad wear sensor has been bypassed or short-circuited to trick the system into thinking the brake pads are not worn. This is often done by connecting the two wires of the sensor together, which completes the circuit and prevents the warning light from illuminating.

Elaboration:

• Why it’s done: Some vehicle owners or less scrupulous repair shops might loop the sensor to avoid the cost of replacing the sensor or brake pads immediately.
• Risks: Bypassing the sensor eliminates the warning system, which can lead to driving with excessively worn brake pads, potentially damaging rotors and compromising braking performance.
• Detection: The car’s computer can often detect this “looping” because the resistance value differs from a new or properly worn sensor. This is why the error message specifically mentions the “looped through” condition.

10. What is meaning of “terminal” in BMW brake pad sensor message and how does the car recognize that a “terminal change place” has occurred?

In this context, “terminal” refers to the electrical terminals of the brake pad wear sensor circuit. A “terminal change place” means the electrical circuit has been interrupted and then reconnected, typically by replacing the sensor. The car recognizes this change through variations in electrical resistance and voltage.

Elaboration:

• Electrical Circuit Monitoring: The BMW’s computer constantly monitors the resistance of the brake pad wear sensor circuit. A new sensor has a specific resistance value. As the brake pad wears, the sensor also wears, changing the resistance. When the sensor is completely worn, the circuit opens, triggering the warning light.
• Reset Logic: When a new sensor is installed (terminal change), the resistance changes back to the “new” value. However, the system needs to recognize this change. This is usually done by resetting the brake pad wear indicator via a diagnostic tool. The act of resetting, combined with the changed resistance, tells the car that a new sensor has been installed.
• Terminal Change Place: The car recognizes a terminal change by detecting the change in resistance when the new sensor is connected and the subsequent reset command issued via the diagnostic tool. Without the reset, the car might still assume the old sensor is present and continue to display the error.

11. How to correct a BMW brake pad sensor bug after a software update?

If the BMW code 5DE0 appears after a software update and you suspect a bug, the best course of action is to first ensure all relevant modules are correctly programmed and calibrated, then perform a reset of the brake pad wear indicator. If the problem persists, further diagnostics might be needed.

1. Sensor Performance

• Extreme Cold: In very cold temperatures, the brake pad wear sensor’s material properties can change, potentially affecting its accuracy. The sensor’s internal resistance might increase, leading to incorrect readings or triggering the 5DE0 code.
• Extreme Heat: High temperatures, especially during heavy braking, can cause the sensor to overheat. Prolonged exposure to high heat can degrade the sensor’s components, leading to premature failure and triggering the 5DE0 code.

2. Wiring and Connectors

• Cold Weather: Cold temperatures can make the wiring harness and connectors more brittle and prone to cracking. This can lead to intermittent electrical connections, causing the 5DE0 code to appear sporadically.
• Hot Weather: High temperatures can cause the insulation on the wires to degrade over time. This can lead to short circuits or open circuits, triggering the 5DE0 code.
• Temperature Cycling: The constant expansion and contraction of materials due to temperature changes can loosen connectors and create corrosion on electrical contacts. This can disrupt the signal from the brake pad wear sensor, leading to the 5DE0 code.

3. ABS/DSC Module

• Module Sensitivity: The ABS (Anti-lock Braking System) and DSC (Dynamic Stability Control) modules rely on accurate sensor data to function correctly. Extreme temperatures can affect the module’s internal components, making it more sensitive to fluctuations in sensor readings.
• Software Glitches: Temperature-related stress can sometimes trigger software glitches within the ABS/DSC module, leading to false error codes, including the 5DE0 code.

4. Brake Pad Material

• Friction Changes: Temperature affects the friction characteristics of the brake pad material. In cold temperatures, brake pads may not grip as well initially, while in hot temperatures, they may overheat and glaze.
• Wear Rate: Extreme temperatures can accelerate the wear rate of brake pads. If the brake pads wear down quickly, the brake pad wear sensor may trigger the 5DE0 code prematurely.

16. What are the long-term consequences of ignoring BMW code 5DE0?

Ignoring BMW code 5DE0 can lead to several long-term consequences, affecting the safety, reliability, and overall cost of maintaining your vehicle. Here are some potential issues:

17. How often should BMW brake pad wear sensors be replaced?

BMW brake pad wear sensors should be replaced whenever the brake pads are replaced, regardless of whether the sensor itself appears to be in good condition. This is because the sensor is designed to wear down as the brake pads wear, and it may not function reliably if reused.

Reasons to Replace Sensors with Brake Pads:

1. Sensor Wear: The brake pad wear sensor contains a small electrical circuit that is designed to break when the brake pad material wears down to a certain point. Once this circuit is broken, the sensor triggers a warning light on the dashboard. Reusing a worn sensor can lead to inaccurate readings and unreliable warnings.
2. Preventative Maintenance: Replacing the sensor along with the brake pads ensures that the entire braking system is functioning optimally. This helps to prevent future issues and maintain the vehicle’s safety and reliability.
3. Corrosion and Damage: Over time, brake pad wear sensors can become corroded or damaged due to exposure to heat, moisture, and road debris. Replacing the sensor ensures that it is in good condition and will function reliably.
4. Cost-Effective: The cost of a new brake pad wear sensor is relatively low compared to the cost of potential brake repairs. Replacing the sensor along with the brake pads is a cost-effective way to prevent future problems.

What if the sensor looks fine? Even if the sensor appears to be in good condition, it is still recommended to replace it. The sensor may have internal damage that is not visible, and it may not function reliably if reused.

When to replace the sensor (if not replacing pads): If the brake pad warning light comes on, but the brake pads are not yet worn down to the replacement point, the brake pad wear sensor may be faulty and need to be replaced. Use a diagnostic tool to confirm that the sensor is the cause of the warning light.
