Review on 🚗 Bosch 16978 Oxygen Sensor: Genuine Equipment for Audi & Volkswagen Vehicles by Daniel Ton

I had an O2 sensor failure. The retailer wanted more than double for the same sensor, so I decided to look for an alternative. This part was found to be compatible with my 2003 Audi allroad 2.7T as well as several other makes/models. In case you didn't know, Bosch is the manufacturer of many VW/Audi parts including O2 sensors. Upon initial inspection, I found that the replacement was identical in shape and construction to the original. It was easy to install and just worked. The kit contains 2 different wiring harness housings. One of them is pre-installed. For my application I had to change the case to another one that was included. Unfortunately, the instructions that come with it don't say much about this part of the process. If you are unfamiliar with the VW/Audi wiring housing, I highly recommend looking for instructions and/or videos on how to remove wire lugs from one housing and install them in another. This is not difficult, but requires know-how, otherwise you can damage/break the housing and/or terminals. Conclusion: The product was compatible and worked perfectly. Easy to install, hassle-free installation. This O2 replacement is identical to the original in form, looks, function and quality, but costs less than half the price you would pay at a specialty store. Featured!
