High quality front brake wear sensor 4M0 615 121 B for FAW Audi RSQ8

This premium OEM front brake pad wear sensor with part number 4M0 615 121 B is a core safety electrical component tailor-made for FAW Audi RSQ8 high-performance SUV. It maintains stable sales volume and continuous repeat bulk orders in global luxury VAG aftermarket, widely stocked by professional Audi performance repair shops and cross-border auto parts wholesalers. We support one-stop bundled procurement together with front brake pads, brake rotors, caliper service kits and full front brake overhaul packages.

Critical brake safety electrical fitting for centralized bulk purchasing

This single-loop resistive wear sensor is clipped onto the inner front brake pad, connected to vehicle ABS/ECU system to monitor residual thickness of brake friction material in real time. It withstands extreme high-temperature radiation from frequent heavy performance braking, constant engine compartment vibration, rain splash and long-term temperature alternation. As a consumable part, it must be replaced synchronously with new brake pads once triggered.

Common failure problems of defective sensors: persistent brake wear warning light on dashboard, intermittent fault alarm during bumpy driving, diagnostic trouble codes on scanner, no reminder even when brake pads wear to dangerous limit. Faulty sensors fail to alert drivers of overworn pads, leading to direct metal grinding on expensive front brake rotors, serious brake performance attenuation and hidden driving safety risks. Most buyers combine this sensor with matching brake spare parts for unified bulk orders, cutting procurement and international logistics costs while securing steady profit margins and low inventory turnover pressure all year round.

100% OEM dimension, wiring length and electrical parameter matching, plug-and-play installation without modification

Manufactured strictly following VAG ETKA factory technical standards. The overall wire length, 2-pin waterproof lock connector, positioning clip shape and built-in conductive sensing wire fully match genuine 4M0615121B. Interchange cross-reference OE codes: 4M0615121AC, 4M0615121P for compatible replacement, exclusively designed for front 420mm large performance brake caliper system of RSQ8, not applicable to rear brake or small standard caliper configurations.

No wiring trimming, adapter conversion or ECU coding adjustment required after replacement. It perfectly clips into the reserved slot of RSQ8 front brake pads and matches original chassis wiring harness layout, drastically shortening brake system disassembly and maintenance working hours.

Full applicable vehicle list

FAW & Imported Audi RSQ8 4MN chassis (2019-2025)
Shared platform performance Audi models: A8 D5, S8, RS6 C8 Avant, RS7 C8 Sportback, Q7 4M SQ7/SQ8
Shared platform luxury models: Bentley Bentayga

Matching powertrain

4.0T twin-turbo V8 high-performance gasoline engine

Installation position

Front axle inner brake pad wear monitoring sensor, fit for factory 420mm front iron brake disc system

Optimized durable structural design

High-temperature resistant reinforced silicone outer wire sheath: Resist baking heat up to 300°C, anti-aging, oil and coolant corrosion resistant, avoid wire cracking and short circuit
Precision thin copper alloy sensing wire: Stable resistance transmission, trigger warning accurately when friction material remains 3mm safety thickness
Waterproof dustproof 2-pin locking plug with built-in rubber sealing ring: Block rainwater and mud intrusion, prevent poor electrical contact and false fault codes
Integrated fixed positioning plastic clip: Firmly lock sensor on brake pad, eliminate wire shake and abrasion against caliper or rotor
Complete single-piece finished sensor assembly, ready for direct replacement along with brake pads

Core vehicle safety protection functions

Real-time transmit brake pad thickness signal to vehicle ECU, activate dashboard wear warning light to remind timely replacement, prevent metal-on-metal rotor abrasion
Withstand extreme heat generated by frequent heavy braking of performance SUV, keep stable electrical signal transmission without failure
Waterproof and shockproof design adapt to all road and weather conditions, avoid sudden brake system monitoring failure during highway and mountain driving
Standard OEM plug structure ensure stable circuit communication, eliminate unnecessary diagnostic fault codes after brake maintenance

Common solvable vehicle faults

Brake pad wear warning light keeps illuminated on instrument panel even with new brake pads
Intermittent brake fault reminder pops up when driving over uneven bumpy roads
Diagnostic scanner reads brake pad wear sensor open/short circuit DTC codes
No warning prompt when front brake pads are severely worn down
Water intrusion causes unstable electrical connection and abnormal alarm

Strict factory testing & stable spot supply

Every batch of wear sensors passes high-temperature aging test, waterproof sealing test, resistance consistency test and vibration fatigue test before shipment, fully complying with IATF 16949 international automotive industry quality certification standards and Audi OEM production specifications.

Adequate spot inventory supports mixed purchase with front brake pads, brake rotors, caliper slide pin grease and complete RSQ8 front brake service kits. Neutral export carton packaging and private label OEM customized labeling services are available for global wholesale purchasers
