hello all
have the amber light on dashboard and suspect the lambda sensors
found them pn LR035750 on ebay
does anyone know how many i need , 1 or 2 of them ?
found these guys https://www.lrparts.net/vehicle/range-rove...odels.html
looks like we have upstream and downstream sensors
i saw two downstream;and two upstream.
i found
LR098290 - EXHAUST LAMBDA SENSOR -
LR098291 - MIDDLE RIGHT HAND OXYGEN SENSOR FOR RANGE ROVER L405,

i am missing the MIDDLE LEFT one, cant find the part number,
seems i need
2x LR098290
1x LR098291
1x ?????????

did run the diagnostic with my foxwell tool
gave me bank1 sensor 3
and bank 2 sensor 3

searched and found a nice explanation on sensor location

it appears that the bad sensors are the rear ones, after cat, thats good they are the easiest to change 2013 L405 V8 5.0 Aspirated Autobiography
