Key Features

• OE-quality Bosch crankshaft position sensor for engine speed and crank angle input
• Robust construction for improved stability through temperature swings
• Expanded operating temperature range for demanding underhood conditions
• Reduced signal drift over the service life
• Direct replacement for select Audi and Volkswagen applications
• Cross-reference: 06A906433C

Detailed Description

Bosch 0261210147 is an engine crankshaft position sensor used by the engine management system to monitor crankshaft position and rotational speed. That signal is critical for ignition timing and fuel delivery calculations, especially on turbo and naturally aspirated engines found in Audi A4, Audi A4 Quattro, Audi A6 Quattro, Volkswagen Passat, and related models. This part number 0261210147 is a practical replacement when the original sensor has become unstable, intermittent, or out of specification.

Compatible With 2000-2006 Audi A4 Quattro, 2005 Audi A4, 2001-2005 Audi Allroad Quattro, 1998-2005 Volkswagen Passat, 2000-2004 Audi A4, 1998-2004 Audi A6 Quattro, 2003 Volkswagen Beetle, 1998-2001 Volkswagen Beetle, 2000-2002 Audi S4, 1998-2001 Audi A6, 2000-2001 Audi TT, 1999-2001 Volkswagen Golf, 1999-2001 Volkswagen Jetta, 2000 Audi TT Quattro, 1999 Audi A4, 1999 Audi A4 Quattro, 1998 Audi A4, and 1998 Audi A4 Quattro as listed in the fitment data.

What It Helps Fix

• Crankshaft position sensor fault codes
• Intermittent no-start or hard-start conditions
• Rough running caused by unstable engine speed input
• Stalling related to incorrect crank signal reporting
• Ignition timing or fuel delivery issues tied to sensor failure

Installation Notes and Tips

Verify the connector style, engine code, and chassis breakpoints before ordering, especially on 1998-1999 Audi A4 and A4 Quattro applications with chassis-specific notes. Compare the original sensor to Bosch 0261210147 and confirm the OE cross-reference 06A906433C when checking interchange. Clean the mounting area before installation and inspect the harness for heat damage or oil contamination that could affect the new sensor signal.

Quality Assurance

Bosch manufactures this crank angle sensor with an OE-focused design intended to maintain stable performance under temperature variation and throughout normal service life. Part number 0261210147 is built for the listed Audi and Volkswagen applications and follows Bosch’s original-equipment engineering approach for engine management sensors.
