Volkswagen Passat Golf Oxygen Sensor 06J906262AA Exhaust Pipe Specific Replacement 0258017270

When your Passat or Golf shows rough idle, noticeably higher fuel consumption, exhaust odor, or frequent engine fault lights, it is usually due to aging oxygen sensor. The sensor monitors exhaust oxygen content and feeds accurate signals to the ECU to control injection; ensures combustion efficiency and emissions compliance. OEM number 06J906262AA, compatible with 0258017270 and 234-5107, for VW Passat, Golf, and multiple models. Installation must be on a cold engine; use a dedicated socket to carefully remove; avoid damaging threads; ensure sensor harness does not contact the exhaust pipe to prevent heat damage.
