BMW 3: Problems with DME air mass system and differential pressure sensor

Check engine light on

Hello everyone, I have a problem with my BMW 3. The engine control 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.
