Hi guys
Recently the MIL light came on, and checking with OBD2 reader throws me that fault: P0135. 
I would like to know if you think that the fault can only be caused by the sensor heater itself. I understand that the only solution would be to change the whole sensor? May be the fuse?
If I have to replace it, despite I chekced servicebox for location... could you tell me which is the easier way to replace the faulty sensor? It's an easy work to do? 
Regards

What engine? Some cars have one sensor, some two.
Also if the heater circuit has failed, new sensor. There aren't any fuses afaik.
Note that the sensor and wiring is critical. So you can't just put any old sensor in their. On the two sensor cars one plug is light blue, the other light green and the wiring legnths are different and not just bevause of their position.
They are usually a pita to remove (several years being cooked). Using a proper lambda sensor socket helps.

Car is 180gti. So it has 2 sensors, faulty one should be the "before cat" sensor I guess. I have OEM number.
The think is; how to replace it? Its mandatory to lift the car?
I wonder if there's any guide for this operation.
Thanks
