Check Engine Light.

[Jasontillett]

Had check engine light (visit workshop) come on.Done an OBD scan and came back with code P0159 which turns out to be faulty oxygen sensor bank 2 post cat.

Purchased 2 brand new  Bosch LS6697 oxygen sensors from eBay for £106 and decided to change both bank 1 and bank 2 myself.

Once I had jacked  back of car up and removed rear wheels,there was a small cover with one torx screw  and two 10mm nuts holding it in place.Once removed you could access the sensors and remove them with a 22mm spanner.The most difficult part was unclipping the plugs which are quite fiddly.

Once replaced new ones and refitted everything did another scan and reset.

Engine now runs and idles a lot smoother and no more CEL.
