Описание: in this vehicle 4238 coming again and again and vehicle giving poor pick up due to blockage of air line in SCR system, air not going properly in side the uria tank. we checked all the current supply to SOV and round coupler of DEF we found good but uria dosing pressure not increasing we try 3 times so we checked the oil separator we found water deposited in side the oil separator, this reason can comes from two sides one are air compressor but when compressor will leak then coolant will deposit inside the tank but we found water deposited in tank. it can happen through the air daring and distribution system , if air dryer will not exhaust the air time to time the water will deposit in side the thanks even the pneumatic system so we corrected the air drying and distribution and cleaned the pneumatic system and do the dosing after changing the uria filter and oil separator then uria pressure was increase up to 600 then both problem 4238 and 3577 were inactive. then all problem got solved.
