I have a EML and a fault codes for bank 1 sensor 1 p223800 and sensor 2 p013600. Must I replace both sensors or is there a work around to get them functioning correctly ?? I have seen o2 sensor spacers being sold online stating they get rid of EMLs does anyone know if they work or not ? My model is a 1.6tdi 2015 110hp if anyone has replaced them do they have the part numbers plz would very grateful thanks.
