Hi got a problem with this one at the moment. P0135 O2 Sensor Heater circuit Bank 1 sensor 1 keeps coming up, we have fitted a NGK sensor and checked & tested the wiring back to the ECU, all good. Also carried out a software update for drivability problems, although it doesn’t have any.
It takes a week or so before the EML light comes back on. We have fitted a load of NGK sensors previously to a lot of cars, but is this a case of needing the genuine O2 sensor? Anyone out there had a similar problem?
