Opel Corsa
90 hp variant of the small Fiat MultiJet diesel. The timing chain declared maintenance-free by the manufacturer is the biggest weakness and can catastrophically break above 150,000 km. EGR and turbo wastegate are further typical wear items.
Reliable diesel
In the slightly heavier D even more focused on economy than driving pleasure.
Engine Weaknesses 4
The timing chain, declared maintenance-free, stretches considerably with long oil change intervals. A broken chain means engine damage from valve collision. Total failure documented at 184,000 km.
Symptoms: Rattling on cold start from the timing chain area, easing slightly as it warms up. Sudden engine failure with heavy smoke in total failure cases.
The wastegate actuator on the IHI turbo seizes in the closed position through heat and ageing, leading to excessive boost pressure and limp mode. Turbo overhaul costs approx. 310 EUR.
Symptoms: Vehicle enters limp mode, severely reduced power, engine warning light, occasional whistling or grinding noises from turbo area.
The swirl flaps in the intake manifold coke up from EGR residues and crankcase ventilation. Complete intake manifold with swirl flaps costs approx. 520 EUR plus 250 EUR fitting.
Symptoms: Juddering and power loss especially on cold running, engine warning light with fault code P2279, poor throttle response in part-load range.
The EGR valve carbons up especially on short trips. Failures documented at 81,000–160,000 km. The valve can be cleaned or replaced; replacement part costs approx. 105 EUR.
Symptoms: Hesitation and juddering when cold, intermittent throttle response at part load, engine warning light, power drop.
Vehicle Weaknesses 13
The electric power steering of the Corsa D fails due to defective control unit electronics (fault code C0550). Broken solder joints and faulty capacitors caused by thermal cycling are typical causes.
On model years 2007–2009, a plastic bearing in the pedal assembly deforms due to footwell heater heat. The brake pedal won't return and the brakes drag permanently.
Coil springs on the Corsa D break frequently, especially on the front axle. According to TÜV statistics this is one of the most commonly flagged faults. Broken springs can damage tyres and bodywork.
Turbodiesels and stronger petrol engines in the Corsa D use the failure-prone M32 six-speed gearbox. Bearing failure through over-preload leads to gearbox failure, recognisable by gear lever wobble.
The Corsa D rear axle carrier is covered by Opel's 10-year corrosion warranty but still rusts heavily. Severe attack makes the vehicle irreparable and unfit for the MOT.
The brake caliper guides on the Corsa D get dirty and stick. Pads seize and grind permanently on the disc — leading to premature wear and overheating.
On model years 2010–2012, the bonnet is missing a drain hole. Water collects in the fold and leads to internal corrosion. Opel officially acknowledged the problem.
On the Corsa D, suspension springs and wheel bearings wear comparatively early. Anti-roll bar links and ball joints are also known weak points.
The Corsa D A/C condenser gets damaged by stone chips or the A/C hoses become porous. Refrigerant loss and compressor magnetic clutch failure are common follow-on problems.
Blocked drain channels in the front area cause rainwater to back up and enter the cabin through body gaps. A faulty rear wiper seal additionally causes water ingress into the boot.
The window regulator motor or guide rail on the driver's side fails. Window can no longer be closed or drops back uncontrolled. Common from 80,000 km.
The cooling fan pre-resistor burns out. The fan then either won't start or runs permanently at maximum speed. Risk of overheating in city driving without functioning fan control.
Vent louver blades, interior mirror mount and dashboard trim pieces in the Corsa D rattle over bumps. Loose clips and temperature-related plastic expansion are the causes.
Reports & Tests
Oil loss occurs about twice as often as average and leads to higher follow-up costs on older vehicles. Axle springs and steering joints are flagged above average. From the third MOT onwards, rear light and indicator failures are added.
