BMW 535d engine shut off during deceleration, unable to turn over or shift from Park on BMW 535d

Some BMW 535d owners report experiencing engine shutdown during deceleration, which can lead to difficulties in turning over the engine or shifting from Park. This issue may be associated with a reduced engine power message, indicating limitations in performance that result in sluggish acceleration and poor overall functionality. Additionally, faulty sensors or actuators can contribute to engine stalling and challenges in restarting the vehicle. Problems with the Diesel Particulate Filter (DPF) have also been noted, which can adversely affect engine reliability and performance over time. Furthermore, some owners have reported timing chain failures that can cause significant engine damage, as well as turbocharger malfunctions leading to throttle response delays. Transmission-related issues may also be a factor, potentially causing stalling or hindering smooth gear shifts. It is advisable for owners experiencing these symptoms to consult a qualified BMW mechanic or service center to diagnose and resolve these critical issues promptly.
