BMW 730d DPF Blocking — Power Loss and Warning Light
Late E65/E66 730d models with M57N2 engine are fitted with a DPF. Short-trip city use prevents regeneration, causing progressive blocking. Symptoms include orange DPF warning light and reduced power. Fault codes P2002/P2463 are stored. Forced regeneration at a garage or a sustained motorway drive resolves early-stage blockage.
