On BMWs the DPF fault will not clear with glow plugs not functioning. Be careful replacing glow plugs in these engines. They are notorious for snapping or stripping threads. Also generic readers sometimes don’t differentiate between glow plug faults and glow plug activation faults which are the glow plug module. Once you have cleared the other faults you can clean the DPF and actually tell the DME that you have replaced it and you’ll get a fresh 160,000 life left.
