NOx sensor replacement
Hi there
Having a wee look around, this seems to be a pretty common issue for a lot of you around the 100k mark.
My 2010 320i is throwing up codes for this very thing and the man says it needs replacing.
Anyone know if it is just the probe that fails? A quick google shows that the probe is about $100, but the probe+plug (sensor?) is closer to $500.
One guy on here ultrasonically cleaned the probe to good effect, so I'm considering trying that in the first instance.
Any help is appreciated.
Cheers
