optimaler Ersatz für den defekten Original-Sensor. Identische Bauform für 1/3 des Preises eines Originalteils.

Fick felkod som pekade på denna komponent. Var lätt att byta själv då den ligger fram på motorn. Super snabb leverans på en söndag och fixade bilen innan helgen var slut. Perfekt komponent som på mekonomen kostar mer än det dubbla! Rekommenderas varmt!

Fits perfectly, used on the exhaust side. BUT in the amazon description the country of origin is Hungary, but on the box it says manufactured in China...What's going on here Amazon!...If I new it was manufactured in China, I would have got OE replacement made in Germany.

I bought 2 sensors to clear my check engine light. At first they worked really good, light was gone and car was running smooth. After a month or two my car started idling really rough and now the car will take too long to turn on when cold. I do not recommend this sensors, you will end up replacing them sooner than later.

Las piezas son de un plástico demasiado endeble en comparación con las piezas originales del coche y acaban rompiéndose al instalarlas. Además, el coche funciona peor con ellas que con las que tenía montadas anteriormente.

The plastic is too soft. While tightening it down the ear with the screw hole will break. When that happens it comes slightly loose, sending an intermittent signal, leading to misfires and no-starts.
