Hi,
Bought a Seat Leon , after 1 week got engine light on >>>> Diagnosed and it was O2 sensor bank1 sensor (1 &2) - replaced both sensors and light still on. Cleared error many times , it keeps coming. Checked fuse box and don't have information regards fuses where some of them missing (not sure is suppose be ) - but the rest fuse checked and all good.
Diagnosed again today and error is P0036: HO2S Heater control circuit bank 1.

Welcome to the community. Worth checkout out our Leon forums for your model of car, I'm sure someone will be able to help.

Hope you get it sorted.

Cheers,

Scott

What brand did you buy? Some cars can be very picky. I tend to only buy Bosch O2 sensors, I had the most success with them with various cars.

Hi I bought from online car part - it's call Ridex

Ridex is the "home" brand from Autodoc, quality is ok, but some things can be very picky as I mentioned before

I cleaned the old sensor and used to see the error still there and yes still there. The problem I don't have a circuit diagram to follow the probe wiring but I do know sensor is fine and measured probe wire and voltage was 8.8 dc as my engine is 1.2 petrol.
