E70 X5M O2 sensor inquiry

vics · 09-19-2019, 12:59 PM

Thanks in advance - could not find much relevant info on service frequency.
2013 I'm @ 55K miles currently.

Is there any need at this point to swap out both upstream & downstream for new or in order or priority, upstream now, downstream later (or visa versa)?

Much appreciated - Vic

Don't worry about them unless you get codes. The car can tell if they aren't giving good readings, or if the heaters fail.

Agree with the previous post and O2's are typically good until 100K+ miles anyway.

Ya they are tough buggers. I have about 150k on mine and they went through hell when it was burning a quart of oil every 150 miles when the turbo oil return lines clogged and my addiction to octane booster. Still working fine even after all of that. That being said, if your going to do a tune or jb4 I reccomend getting new ones, EVERYTHING rides on them being 100 percent
