BMW 5 Diesel Cold Start Issues: Fuel Heater Problems?

Unsteady engine

Poor fuel economy

Longer cold start time

Loss of engine power

Hey everyone! My 2009 BMW 5 diesel has been acting up lately. The engine struggles to start in cold weather, runs with reduced power, and idles rough. Fuel consumption has increased noticeably too. I suspect it might be related to the fuel filter heater, but I'm not entirely sure. Has anyone dealt with similar symptoms? If so, what was the actual problem and how did your mechanic fix it? Really interested in hearing about your repair experiences. Thanks in advance
