Where is it?

[Jules]

Hi all, I realise this is a silly question but please can some-one explain or post a pic of where the Lambda sensor is that would cause this fault 16514 P0130 O2 Sensor Circ.,Bank1-Sensor1 Malfunction is located please. Would a cheap one do the job? The car is a 2002 Leon Cupra 1.8T 20v with no modifications. Thank you

The lambda sensor sits on the downpipe. The 20VT has 2 lambda sensors, one which measures exhaust gases and a "control" lambda.

The bottom one is the stock downpipe, you can see the lambda connection in the neck.

Get a proper one, get OEM or correct Bosch. Correct fueling is important as you might suspect...

Thank you for the reply. I will look at getting a Bosch replacement, will I need to replace both?

Usually only the front, do you have access to vagcom? You can check the workings of the lambda sensor there.

Dont have access to Vagcom, well only a free version that reads/clears faults. Will just replace the front one and see. Thanks for the advice
