Hi,

The engine light just came on when driving my 2002 Octavia. Checked the fault codes via VAG-COM and it came up with :

16519 P0135 O2 Sensor Heater Circuit - Malfunction (Bank 1 Sensor 1)

Where is that sensor located and an estimated price??

Been reading some more now and can it be the front lambda before the cat? Part# 021906262B ?

Underneath the car infront of the cat. Wire connects under the black plastic housing (held on by two 10mm nuts).
