Volkswagen/Audi A5 Front Oxygen Sensor 8R0906262B 025802706 Direct Replacement

For VW Tiguan, Magotan, Passat, and Audi A5/Q5 with 2.0T engines, the front oxygen sensor can directly replace OEM numbers 8R0906262B and 025802706. It uses zirconia ceramic core and high-temperature stainless steel housing; welding workmanship meets OEM standards, withstanding long-term exhaust exposure and thermal cycling fatigue to avoid early false alarms from cheap aftermarket parts. It monitors exhaust oxygen content and feeds ECU to adjust air-fuel ratio; if idle is unstable, fuel consumption rises, or check engine light is on, replacing this sensor restores performance.
