Hello together! Since I drive on Friday with the thickness on vacation, I sent my wife to FOH today. Make error memory read out. Result: error message air mass meter error message AGR valve Furthermore it was found that a “connection” T-piece is leaking in the return line of the injectors. That would explain the bad start behavior and the light diesel smell for some time. That the ZV actuator is in the driver’s door o.F., I had already s The FOH has apparently tried, but has not found the T-piece in the part program. Now my questions: – Does anyone of you have the opportunity to find out the part number? – The air mass meter is only 3 years old, can it actually be over again? – The AGR valve is closed by plugging in the underpressure line. Can this set the error code? – Can the LMM error be triggered by the shut down AGR valve where The FOH explicitly said error message LMM, not that the LMM must be defective…… Greeting Robert
