Opel Meriva
Opel's own 1.7-litre common-rail diesel that replaced the Isuzu Z17DTH. Thermally well designed but with known weaknesses in the EGR system and timing chain. Short-trip use is poison for this engine.
Meriva diesel base
81 kW diesel in the Meriva B – fitting engine for the city van.
Engine Weaknesses 5
The EGR cooler can develop an internal leak allowing coolant into the intake. This results in gradual coolant loss and, in worst case, engine failure through overheating.
Symptoms: Gradual coolant loss, white smoke from exhaust, bubbles in coolant reservoir, coolant temperature rising abnormally.
The variable geometry turbocharger can seize at the vanes due to soot deposits. Aggravated by EGR and DPF problems and short trips. Limp mode at 2,500 rpm is typical.
Symptoms: Engine management light, power loss with limp mode at approx. 2,500 rpm, boost pressure fault code, whistling from turbo.
The timing chain can stretch prematurely with neglected oil change intervals. Rattling on cold start indicates wear. If the chain breaks, catastrophic engine failure follows.
Symptoms: Rattling or ticking on cold start from the timing chain area, noise fades on warm-up, engine management light at advanced wear.
The EGR valve carbons up with soot deposits and sticks open or closed. Typical problem on short trips without reaching the self-cleaning temperature.
Symptoms: Power loss under full load, misfires at low rpm, engine management light, elevated exhaust soot.
The metering unit of the high-pressure pump regulates common-rail fuel pressure and can fail through wear. Replacement is inexpensive; a failed pump itself is costly.
Symptoms: Rough idle, misfires between 1,500 and 2,000 rpm, hot-start problems, engine stalling shortly after start.
Vehicle Weaknesses 12
The drain plate on the Meriva B has a design flaw that allows water into the footwell. The accumulated water damages the ABS control unit located beneath it.
Meriva B models up to 2015 were recalled due to material fatigue in the seatbelt retractor housing. In a collision the retractor can fracture and lose its restraint effect.
Meriva B from model year 2013 can develop cracks in the steering rack which in the worst case can lead to steering failure. A recall was carried out for affected vehicles.
Rust forms behind the plastic wheel arch covers, often only visible when removed. Paint blisters appear on lower door edges. Front subframe rusts from the inside.
The hollow front subframe collects moisture and rusts from the inside out. Control arms and track rod ends wear early due to the compact wheelbase.
On the Meriva B the rear brake caliper carriers stick, especially with BOSCH brake pads. Uneven wear and overheating of the rear axle are typical consequences.
On the Meriva B the expansion tank cracks at weld seams. Escaping coolant can damage the ABS control unit located beneath it.
Defective rear light seals allow water into the boot in rain, which collects in the spare wheel well. Additional entry points: blocked AC drain hose.
Window regulator motors and cables fail regularly, especially at the rear FlexDoor doors due to their special hinge geometry. Cable breaks at the door fold are common.
The window regulators of the Meriva B — especially on the rear butterfly doors — fail due to defects in the cable or motor. Windows get stuck open or closed.
On the Meriva B the plastic pin of the blend flap actuator breaks, causing the flap to fall to the cold position. Removal requires stripping the complete dashboard.
On the Meriva B the seat heating fails at the highest setting (level 3), while levels 1 and 2 continue to work. Cause is increased resistance in the heating element.
Reports & Tests
The Meriva B shares many weak points with the Crossland X: oil loss from the first MOT, premature spring wear and brake disc wear. The rear doors opening in opposite directions cause seal problems with age.
