BMW 3: Problems with DME air mass system and differential pressure sensor
(Translated from German)
Summary of the thread
A BMW 3 owner is experiencing persistent engine control light issues with error codes 002D06 and 002D29, related to the DME air mass system and differential pressure sensor. Despite replacing the differential pressure sensor and LMM, the problem remains. A suggested solution is to check for air leaks in the intake system, inspecting hoses, connections, and the intake manifold for damage or leaks, and repairing or replacing any faulty components.

Hello everyone, I have a problem with my BMW 320i n43. The check engine light is on and I get the error codes 002D06 (DME air mass system) and 002D29 (DME differential pressure sensor, intake manifold: plausibility). I have already replaced the differential pressure sensor and the LMM, but the errors persist. Do any of you have experience with these errors and can help me further? Many thanks in advance.
Since you've already replaced the differential pressure sensor and the LMM, the next step could be to check for any air leaks in the intake system. A leak could cause these error codes. Inspect all hoses, connections, and the intake manifold itself for any signs of damage or leaks. If you find any, they'll need to be repaired or replaced. Please update us on your progress.
