I barely drive my Discovery, maybe 2k miles a year since 2014. Before that it saw pretty normal use. I think I’ve changed all 4 O2 senors 2x or more since 2009, mostly bosch. Has anyone else experienced anything like this?

 

At least 2 sets of fronts in the last 5 years. Never touched the rears. No reason to. I like Walker brand now.

 

I guess these trucks just churn through O2s?


anyone else changing them at obscene intervals?

 

Quite a few things can trigger o2 sensor faults.

 

I have had my Disco since 2003 from 79K miles to the current 157K miles. Touch wood, I have had only changed one sensor about 7 years ago.

 

Changed one this year wire was worn through, will change the other front have the other 3 in a box they are getting slow.

 

Fronts twice. Rears once.

No cats so it's easy. I installed cat foolers on the rear so no cel

Fronts died quickly the first time due to valve cover and head gasket coolant leaks. We took the +200k mile rig with zero service history and put her into daily driver duty in a week so there were bound to be growing pains

Been good for a long while now. Knock on wood.

 

I have never changed an O2 sensor on any vehicle I’ve had. I probably shouldn’t say this as I may now need one in the near future.

 

you sir have just awoken the Rover gods. Good luck.

 

I thought similar thoughts as I wrote it.
