Range Rover TDV6 Timing Chain Problems: Causes, Symptoms & Fixes
Range Rover TDV6 and SDV6 engines actually run a belt-driven timing system (front, rear, and HPFP belts), not a true timing chain, though the terms often get mixed up online. Worn tensioners, aging or contaminated belts, and missed service intervals can trigger cold-start rattles, rough idling, or in worst cases catastrophic engine failure, since these are interference engines. This guide breaks down the real symptoms, causes, replacement costs, and what to check before buying a used TDV6, so owners can catch problems early instead of facing an expensive rebuild.
