O2 Lambda Sensor VW Polo Golf Skoda Fabia Rapid 04C906262J 0258030131 AKAS

The AKAS O2 Lambda Sensor is a precision direct-fit upstream (pre-catalytic converter) replacement for VW Polo, Golf 7, Jetta, T-Roc and Skoda Fabia Mk3, Rapid models equipped with the EA211 1.0 MPI / 1.6 MPI petrol engine (CHYA, CHYB, CWVA), replacing OE 04C906262J (Bosch ref: 0258030131).

Manufactured to strict OE specifications with a 4-wire heated design, the high-precision sensing chip captures real-time exhaust oxygen levels and transmits fast air-fuel ratio data to the ECU - restoring optimal fuel economy, reducing emissions, and clearing check engine lights. Premium high-temperature alloy probe with anti-carbon and anti-corrosion coating ensures long service life. Plug-and-play OE connector enables straightforward installation. Backed by a 6-month limited warranty.

• Exact OE Match - VW & Skoda EA211 1.0/1.6 MPI Precision upstream (pre-cat) direct-fit sensor for VW Polo, Golf 7, Jetta, T-Roc and Skoda Fabia Mk3, Rapid with EA211 1.0 MPI (CHYA/CHYB) / 1.6 MPI (CWVA) engine. Replaces OE 04C906262J (Bosch 0258030131), with 1:1 OE dimensions and 4-pin connector - no modification needed.
• Fast-Response Precision - Restores Fuel Economy & Clears CEL High-precision sensing chip captures real-time exhaust oxygen concentration with minimal signal deviation. Fast-response module transmits air-fuel ratio data swiftly to the ECU, restoring optimal fuel efficiency, reducing emissions, and clearing check engine lights caused by a faulty sensor.
• Premium High-Temp Construction - Anti-Carbon, Long Lifespan Premium high-temperature alloy probe with oxidation-resistant outer shell delivers reliable performance under harsh exhaust conditions. Anti-carbon-build-up and anti-corrosion coating resists erosion from hot exhaust fumes, significantly prolonging service life vs. uncoated cheap sensors.
• 4-Wire Heated Plug-and-Play - Upstream Pre-Cat, OE Connector 4-wire heated design brings the sensor to operating temperature quickly after cold start, ensuring accurate monitoring even during short urban trips. Upstream (before catalytic converter / regulating sensor) position with OE-matching 4-pin connector and M18x1.5 thread - true plug-and-play, no splicing required.
• OE Quality at Aftermarket Value - 6-Month Warranty Manufactured to strict OE specifications with dependable detection accuracy, rapid signal feedback, solid high-heat tolerance, and anti-vibration capability. Backed by a 6-month limited warranty covering manufacturing defects - peace of mind for VW and Skoda owners in South Africa.

Note: Verify your original OE number and engine code before purchase.

VERIFY COMPATIBILITY: This upstream (pre-cat) sensor fits ONLY VW Polo 6C, Golf 7, Jetta, T-Roc and Skoda Fabia Mk3, Rapid with EA211 1.0 MPI (CHYA/CHYB) / 1.6 MPI (CWVA) engine, replacing OE 04C906262J. NOT compatible with other engine sizes, TSI/TDI diesel engines, or downstream (post-cat) position. Check original OE number and engine code before purchase.

PROFESSIONAL INSTALLATION: Recommended for proper torque (30-45 Nm), correct cable routing away from heat sources, and clearing of diagnostic trouble codes after replacement. Allow exhaust to cool completely (30-60 min) before servicing. Do not over-tighten.

HANDLE WITH CARE: Do not drop, bend cable sharply, or touch the probe tip with bare fingers. Do not apply solvents to the sensing element. Apply copper anti-seize to threads only - avoid probe and connector. If mounting bung thread is damaged, repair before installation.

WARRANTY: 6-month limited warranty covering manufacturing defects under normal use. Does not cover improper installation, drops, contamination, water ingress, incompatible vehicles, modification, or normal wear. This is an aftermarket replacement part - not affiliated with or manufactured by VW Group or Bosch.
