hello , I have a Qashqai DIG-T 115 ACENTA M1.2 (2014 model). I have a DTC P0135 engine fault, as my engine warning light is constantly On.
I got it checked by a local Nissan dealer and I am told it needs an O2 sensor heater B1 replaced. Could you pls advise what would be the cost of that and if there is anything else I can check before getting it replaced? I am in UK. Thanks
