Opel Zafira
The 1.6-litre CDTI from the GM/PSA partnership is economical and powerful, but suffers from a systemic timing chain problem. Rattling on cold start is widespread and regarded as a known weakness. Timing chain and tensioner should be checked regularly at higher mileage.

100 kW in the Zafira Tourer – solid for the van.
Engine Weaknesses 4
The timing chain rattles on cold start due to a slow-reacting tensioner. The tensioner is mounted on the gearbox side and is difficult to access. Opel developed a revised tensioner.
Symptoms: Metallic rattling for 1–4 seconds on cold start, sometimes also under load changes when warm. Noise originates from the gearbox side of the engine.
Mandatory recall for illegal defeat device. The software update significantly raises the EGR rate, leading to accelerated carbon buildup in the EGR valve, intake manifold and pressure sensors.
Typical diesel problem, amplified by the emissions scandal software update: soot deposits in the EGR valve and intake manifold reduce engine performance. Cleaning every 60,000–80,000 km recommended.
Symptoms: Power loss under part throttle, hesitation when pulling away, elevated fuel consumption, black smoke, engine warning light.
Early turbocharger failures were documented, in some cases below 10,000 km. A software update increased oil pressure and resolved the problem in known early-failure batches.
Symptoms: Power loss, whistling noise from the engine bay, bluish smoke, boost pressure fault code P0299.
Vehicle Weaknesses 16
Tie rod end not sufficiently tightened to the steering knuckle. In the worst case, severely reduced steering control.
Suspension springs cannot cope with the high kerb weight and full 7-person loading. Broken springs lead to MOT failures.
Rear axle rubber bushings wear out and become loose. MOT inspectors flag this as excessive play in suspension arms. Wheel alignment is required after replacement.
Software fault can cause the hill-start assist and electric parking brake to operate incorrectly, potentially leading to uncontrolled rolling.
Suspension springs break after just a few years, especially on the front axle. Frequent MOT failures.
Air conditioning frequently develops leaks and loses refrigerant. Complete loss of cooling performance.
The Radio-Nav900 system powers itself down and restarts at regular intervals. Cause is a temperature problem in the unit.
The 6-speed M32 manual gearbox does not always shift cleanly, especially when cold. Bearings and synchro rings wear at higher mileages.
The heated seats on the driver and passenger side fail — a well-documented issue confirmed in multiple forums.
Brake discs and pads wear above average. Frequent MOT complaints.
Headlights and tail lights malfunction. Frequent MOT complaints even after just three years.
On the Zafira Tourer, seam sealant between roof and pillar tears open, allowing water to enter the A-pillar and interior.
The Zafira Tourer develops rust on lower door edges and rear wheel arches from around 6–8 years old. Sill rust starts at the door seal recess.
On the Zafira Tourer, the plastic coolant expansion tank cracks at pressure points and hose outlets. Slow coolant loss often goes unnoticed.
The Zafira Tourer's centre and rear silencers rust through quickly with frequent short-trip use. Leaks lead to increased noise.
In the Zafira Tourer, headlining fixings (only hook-and-loop tape) come loose and creak with temperature changes. Dashboard trim panels also vibrate.
Reports & Tests
Oil loss from engine and gearbox is the most common reason for failing the MOT. Axle springs fail earlier than usual under the higher vehicle weight. Compared to its predecessor, clear quality improvements in suspension and electronics.
