Just pondering replacing the upstream O2 sensors. Looks straightforward-ish in the manual.
Had a quick look under the vehicle. LH side could not quite see the nut which holds on the elec connector cover - is this better accessed from the side with the front wheel off?
Any tips? Have not done O2's before. They should be low-torque, but obvs may be prone to seizing I am thinking given environment?

I've got a 2010 range rover hse and just changed my o2 sensors. The two rear and passenger side ones were easy from under the car but I couldn't reach the drivers side front sensor until I removed the exhaust. the whole project would have been faster if I had removed the exhaust at the beginning.

Regards,
Jon
