Hello all,

Took the X5 for inspection and failed for Emission codeP0141. Anyone know what it entails?

P0141 O2 Sensor Heater Circuit Malfunction (Bank 1 Sensor 2)

Thanks Zulu95. Is this something I can do, or do I take it to a pro?

You need to change the O2 sensor with a readily available add on tool for your socket wrench.
No expert but I would say it's the rear sensor after the cat. If this has gone you can expect others to follow.
