Default New Car, Faulty NOx Sensor

Last week I picked up a new Passat TDI (2013 leftover) and on my first day with the car and only 93 miles, the check engine light came on. I brought it back to the dealer who informed me the NOx senor was bad and that I would need a new one. Is this a common problem and can I expect more issue with the car down the road? Is it possible that it went bad from sitting for too long and not being used?

Multiple posts for the same thing are frowned upon here. It was already answered in your other post.

Typically an electronic device will fail (if it's going to fail) very quickly. Once past that initial hour or so, then the rate of failure dips to a very low level. I suspect that your sensor was just one of those somewhat rare components destined to give up early in life.

My NOX module shorted out yesterday, $700 later it's fixed. Can't complain after 87k miles it's the first thing to go bad

Not on the 13's been down that road, still have the light on... for over a year. Someday i'll find a wrecked car with one on it and replace then. Till then i can handle a light and no effect in mileage....

That wasn't his point— but I think you know that. In case it's not clear: it was about multiple posts, not a welcome statement. And it was perfectly appropriate.

Look at the date.... this is an old post resurrected. If (back in the day) two or three posts showed up in a line all about the same problem, i would have answered one and said this in the other two as well...

I stand corrected, didn't look at the date. So why does it say Newbie under his name seeing as this is an old post? Just wondering and I should have looked closer though. Thanks everyone for straightening me out.

Newbie and "member" and "veteran" i think is determined by how many time you post not by date....
