Timing Belt Faults
18 known faults tagged with Timing Belt
Timing Belt Failure
CriticalThe 1.4 TDI Fabia has a timing belt with a 60,000-mile or 4-year interval. Belt failure on this interference engine is catastrophic — bent valves and destroyed pistons are the result.
Timing Belt Failure
CriticalThe Punto 1.3 Multijet uses a timing belt with a 60,000-mile interval that Fiat owners frequently overlook. Belt failure on this interference engine is catastrophic.
Timing Belt Failure
CriticalThe 2.2 TD4 Evoque uses a timing belt that must be replaced at 120,000 miles or 10 years — but many specialists recommend 80,000 miles given the consequences of failure.
Timing Belt Failure (60,000-Mile Interval)
CriticalThe 1.6 BlueHDi carries forward the PSA 60,000-mile timing belt interval from the 207. Many 208 owners are unaware — belt failure destroys the engine.
Timing Belt Failure (60,000-Mile Interval)
CriticalThe 308 Mk1 1.6 HDi carries the same strict 60,000-mile belt interval as the 207. Many 308 owners are misled by the larger car into assuming a longer belt life.
Timing Belt in Oil Failure (Wet Belt)
CriticalThe 1.2 PureTech engine uses a 'wet belt' timing system — the belt runs in engine oil. This reduces noise but the belt degrades faster than a conventional dry belt. PSA extended the replacement interval, but early failures occurred.
Timing Belt Failure
CriticalThe B8 A4 2.0 TDI uses a timing belt with a 140,000-mile service interval. Many specialists recommend 100,000 miles. Belt failure is catastrophic on this interference engine.
EGR and Timing Belt Failure
CriticalThe Q5 TDI shares the EGR cooler failure of the wider VAG TDI family, plus the timing belt must be replaced at 140,000 miles — a job many owners defer dangerously.
Timing Belt Failure
CriticalThe 1.2 TDI Polo has a timing belt that must be replaced at 60,000 miles or 4 years. Many owners are unaware of this interval — belt failure destroys the engine on this interference unit.
Timing Belt Failure (CFFB/CEGA Engines)
CriticalUnlike the older PD-engine Passats, the B7 common rail 2.0 TDI uses a timing belt. The belt interval is 140,000 miles but many specialists recommend 100,000 miles given the cost of engine damage.
Auxiliary Belt Tensioner Failure (Engine Destruction)
CriticalA catastrophic design flaw on the 5-cylinder D5 engine. The auxiliary (alternator) belt tensioner fails, snapping the aux belt. The debris gets sucked into the timing belt, destroying the engine.
Camshaft Chain Tensioner Wear (16v models)
SevereOn the 16-valve versions of the 1.6 HDi, there is a small timing chain connecting the two camshafts (driven by the main cambelt). The chain tensioner wears, causing a rattle and potential timing slip.
Water Pump and Timing Belt Failure
CriticalThe water pump on the 2.0 TDI is driven by the timing belt. If the pump fails or seizes, it destroys the timing belt, leading to catastrophic engine damage.
Timing Belt Failure (Z17DTH)
CriticalUnlike the later Astra J (which has a chain), the Astra H 1.7 CDTi (Z17DTH engine) uses a timing belt. Belt failure is catastrophic on this interference engine. The service interval is 60,000 miles or 4 years.
Timing Belt Failure and Water Pump Failure
CriticalThe 2.2 SD4 Freelander 2 has a timing belt with a 120,000-mile interval but the water pump is driven by the same belt — and water pump failure destroys the belt. This is a common and expensive failure.
Timing Belt Failure (60,000 Mile Interval)
CriticalThe PSA 1.6 HDi engine has a 60,000-mile or 4-year timing belt interval — much shorter than most competitors. Belt failure destroys the engine. Many 207 owners are unaware of this critical maintenance item.
Timing Belt Failure (Short 36,000-Mile Interval)
CriticalThe 0.9 TwinAir engine has an unusually short timing belt interval of just 36,000 miles or 3 years. This is poorly publicised and many owners miss it. Belt failure destroys the engine.
Timing Chain Failure (K9K Engine)
SevereThe Renault/Nissan K9K 1.5 dCi engine in the Qashqai J10 is known for timing chain wear. Unlike a timing belt, there is no scheduled replacement — but chains stretch and tensioners fail.
