2009 GL320CDI BlueTec Nox Sensor Problem or Catalytic Converter Problem
hi. i bought 2009 Gl320. CEL is on. checked with my launch computer and it showed that two Nox sensors gives error and also the pressure in the AdBlue system is too low.
Error 14B500 Component Nox sensor or upstream of SCR catalytic converter has plausibility error
Error 153500 Component Nox sensor or downstream of SCR catalytic converter has plausibility error
Error 20E823 The pressure in the AdBlue is too low
i cleared codes first time and as sson as drove like 2 miles CEL was back on. so i cleared it again and drove the car like 40 miles distance with 3000 rpm,was hoping to clean the catalytic converter. and this time CEL came back on in 20 miles after 40 miles with 3k rpm,so basically in 60 miles total. car has 84000 miles. my question - can Nox sensor malfunction because catalytic is not clean or if catalytic was not clean i would had a different error codes about it. also can adblue error can be because Nox sensors errors. Basically do i need to clean catalytic or i need to replace two sensors first,it is just strange that both not working at the same time. thanks.
