Bosch Crankshaft Position Sensor 0261210199 for Audi & VW — OE Fit, Digital Sensing

This Bosch sensor replaces factory-installed crankshaft position sensors on many Audi and Volkswagen models, delivering the same electrical characteristics and mounting fit as the original part. Built to Bosch OEM standards, it uses a digital sensing element and robust housing materials to resist electrical interference, vibration and extreme temperatures so your engine control module receives a clean, stable speed signal.

How does this sensor affect ignition timing and engine control?

The crankshaft position sensor measures the rotational speed and position of the crankshaft, information that the engine control unit (ECU) needs to set ignition timing and fuel injection events. When the sensor provides an accurate waveform, the ECU can maintain consistent spark timing and fuel delivery under all driving conditions.

• Precise digital measurement of rotational speed for stable ECU inputs
• High resistance to external electrical interference preserves signal clarity
• Wide temperature tolerance reduces drift in hot or cold environments
• Direct OE fit reduces installation variability and alignment issues

What vehicles and OE numbers does BOSCH 0261210199 replace?

This Bosch unit is designed to replace specific OE part numbers and fit many Audi and Volkswagen engines, though engine code and year can affect fitment. Always verify fitment using your vehicle details or the fitment checker to confirm compatibility before purchase.

• Replaces OE numbers 06A906433B, 06A906433G, 06A906433L, 06A906433N
• Common fits: Audi A3, A4, A4 Quattro, TT, TT Quattro, TTS Quattro (select years)
• Common fits: Volkswagen Beetle, Eos, Golf, Golf R, GTI, Jetta, Passat (select years)
• Note: verify engine variant and production year for precise compatibility

How durable and reliable is this Bosch crankshaft sensor?

Bosch manufactures this sensor to meet Original Equipment specifications, so the design emphasizes longevity and consistent performance. The sensor’s robust construction and noise immunity help it survive under the heat, vibration and electrical disturbance conditions found in modern engines.

• Engineered for long service life and consistent signal quality
• Housing and connector designed to resist vibration and contaminants
• Operates across a wide temperature range to prevent thermal degradation
• OEM-level tolerances ensure repeatable performance after installation

What should I expect when installing the replacement sensor?

Installation is straightforward when replacing a like-for-like Bosch OE sensor: it mounts in the factory location and connects to the existing wiring harness. Still, basic precautions—disconnecting the battery, using the correct torque, and checking alignment—help ensure the sensor reads accurately once installed.

• Direct OE-style fit for predictable mounting and connector match
• Minimal additional parts required—typically swaps into original bracket
• Verify connector seating and wiring integrity to avoid signal faults
• Clear diagnostic trouble codes after replacement if present

Who is this for: Drivers and technicians seeking a cost-effective, factory-equivalent replacement for a damaged or worn crankshaft position sensor on compatible Audi and Volkswagen models. It’s especially suited to owners who want OE-level accuracy and durability without dealer packaging premium, and to repair shops that demand consistent fit and signal performance for engine control systems.
