Help Needed: Persistent Power Loss and Engine Issues in BMW 318d MSport
Summary of the thread
A BMW 318d MSport is experiencing persistent power loss, engine performance issues, and poor fuel economy, despite replacing the MAF sensor. Diagnostic tools indicate problems with the MAF, DDE, and glow plugs 1 & 2. A suggested solution is to check for vacuum leaks in the intake system, as these can cause similar symptoms. Inspecting and repairing any damaged hoses or connections may help resolve the issue.

Check for any vacuum leaks in the intake system, as these can cause similar symptoms and affect engine performance. Inspect hoses and connections for any signs of wear or damage. If you find any issues, repair or replace the affected parts. Let me know how it goes or if you have any further questions!
