Had this come up on vagcom, Cleared and come back.

Worked fine until i put my sports cat on.

17526 - Oxygen (Lambda) Sensor Heating: B1 S2: Open Circuit
P1118 - 35-00 - -
17522 - Oxygen (Lambda) Sensor: B1 S2: Internal Resistance too High
P1114 - 35-00 - -
16524 - Oxygen (Lambda) Sensor B1 S2: No Activity
P0140 - 35-00 - -

Tried unpluggin and repluggin same thing.
Is this the one before or after cat?
Should i just replace it with a universal or proper job.

Cheers jay

after the cat.
b1= bank 1
s2 = sensor 2
replace with proper one as resistance needs to be correct for ecu

that the resistance of the sensor is too high,which can be measured in ohms.
but is probably down to damaged internals.

u beat me 2 it! i have just had this same problem with mine! the engine management light came on so i took it to the dealers and they cleared the fault and it was fine over the weekend , but lastnight it came back on. So i took it back to the dealers 2day and the lambda probe after the cat is faulty. I got told £164 to change it all in!
