A few lambda fault codes... help !!

[Cupra_Jeff]

Hello all, I've recently had these two faults thrown up on the ECU, no engine warning lights etc, runs fine......

16518 - Oxygen (Lambda) Sensor B1 S1: No Activity
P0134 - 35-00 - -

17524 - Oxygen (Lambda) Sensor Heating; B1 S1: Open Circuit
P1116 - 35-00 - -

Is this a classic sign of dead pre cat lambda sensor ? If so how do I rectify it, simply replace the lambda sensor ? Its just I've got an MOT coming up soon and surely it'll fail on the emissions with a dead lambda won't it ?

How much is a new lambda and how tricky is it to change without a pit or anything ?

easy enough to swap if you can get it on axle stands

yep looks dead,

I got a second hand one if your interested, bought new cause i was fault finding and fault was still there lol so the lambda was ok, yours for £40 all in (retail £90+vat)

cupra is different, had mine from euro car parts and it was a hell of a lot more
