correct front sensor for a 2.0T engine
replaced the original sensor seamlessly, this one is the wideband type, not a normal narrowband sensor

This worked for my 2008 Touareg V6 gas
Put that this Bosch in and it passed smog (previously got a P0430 error). I went through 2 sensors (both said they fit my car) before figuring that you need to stick with what works. My original O2 Sensor was discontinued (number is stamped on the side of the sensor), but research from the web said this was the replacement number (Bosch Oxygen Sensor - 17178) . Previous to that, the sensors, although looking identical and fit the connector, would give me an error - P2234. Hope this helps.

Exact fit connector wise for an 2012 Audi A5 Quattro
Connector fits great but wire length is much longer than OEM. I just folded the wire almost like in the packaging picture and used the enclosed zip ties for a neat fit. Extra zip ties came in handy when I replaced the downstream Oxygen Sensor which did not include and extra mounting parts.

Save money with this perfect oem fit
2014 Audi allroad 110k miles Perfect oem fit, instantly cured my cars stuttering at 2k rpm You'll need a large bar to remove the old one though since it's on so tight and probably frozen in place , at least I did. Otherwise it took a few minutes to install.

2013 Audi A4 Quattro
I had DTC P0030(O2 heater circuit not working properly) Swapping out sensor fixed the problem. No need to have the new sensor be "learned" by ECU.

Easy install
Fit perfect and easy to install. Go to your local auto parts store and buy the proper Oxygen sensor socket ($10-15).
