✓ The faults of this engine were checked against sources (10/2026). Each item has at least two independent sources or an official recall or parts-maker technical note.
Turbo failure: oil feed pipe and banjo filter blocked by carbon (16v)
usually 60,000–200,000 km · High risk
model years 2004–2011 onlyengine codes: DV6TED4, DV6ATED4, 9HX, 9HY, 9HZ, 9HV
Signs: Whistling or loss of boost, blue smoke, oil in the intercooler pipes; a new turbo can fail again within a few thousand km
Fix: Replace the turbo with new oil feed and return pipes and banjo bolt, clean the sump and oil pick-up strainer, flush the oil twice, then change oil every 10,000-15,000 km
€800–1,700
Injector copper washers leak: carbon build-up ('black death', 16v)
usually 60,000–200,000 km · High risk
model years 2004–2011 onlyengine codes: DV6TED4, DV6ATED4, 9HX, 9HY, 9HZ, 9HV
Signs: Ticking or puffing from the injectors, exhaust smell in the cabin, black tar-like deposits around the injectors, harder starting
Fix: Remove the injectors, clean out the carbon and re-cut the seats, fit new washers and clamp bolts on all four; repair early, because the soot gets into the oil and ruins the turbo
€150–800
Camshaft chain stretch and cam lobe wear (16v, early engines)
usually 80,000–250,000 km · Medium risk
model years 2004–2011 onlyengine codes: DV6TED4, DV6ATED4, 9HX, 9HY, 9HZ, 9HV
Signs: Rattle from the top of the engine, rough or unstable running as the valve timing drifts, engine warning light
Fix: Replace the camshaft chain and tensioner, inspect the cam lobes and followers and replace worn parts
€350–1,000
Timing belt pulleys / tensioner noisy or corroded (16v)
usually 60,000–200,000 km · Medium risk
model years 2004–2011 onlyengine codes: DV6TED4, DV6ATED4, 9HX, 9HY, 9HZ, 9HV
Signs: Whine or rumble from the timing belt side, rust on the pulleys; a few belts broke before the interval
Fix: If it is noisy, replace the timing belt kit (belt, tensioner, idler) early instead of waiting for the full interval
€250–500
Injector faults on early 8v engines (knocking, jerking)
usually 60,000–180,000 km · Medium risk
model years 2010–2014 onlyengine codes: DV6C, DV6D, 9HP, 9HD, 9HF, 9HL
Signs: Knocking at low revs, jerking in the lower gears, hard cold starts, injector fault codes
Fix: Read the injector corrections and do a return-flow test; recode or replace the faulty injectors
€250–1,400
EGR valve sooting
usually 80,000–200,000 km · Medium risk
Signs: Jerking, black smoke, power loss or limp mode, EGR fault codes; mostly on cars used for short trips
Fix: Clean or replace the EGR valve; cleaning often helps only for a while
€100–600
