Opel Agila
Suzuki three-cylinder in the Agila B. Robust and economical, but only 48 kW which is on the weak side. Timing chain maintenance-free; hardly any known weak points except occasional ignition coil issues.
Nippy in the city
The 1.0 nips through city traffic briskly but feels sluggish on throttle response and loses momentum on inclines. Enough for daily use, but no driving pleasure.
Engine Weaknesses 6
At higher mileages the valve stem seals can become porous and allow oil into the combustion chamber. Classic symptom is blue smoke from the exhaust, especially on cold start and overrun.
Symptoms: Blue exhaust smoke on cold start or overrun, dropping oil level with no visible external leak, sweet smell in exhaust
The thermostat can fail at higher mileage – either stuck open (engine never reaches operating temperature) or stuck closed (risk of overheating). Coolant loss through porous hoses also documented.
Symptoms: Engine does not reach operating temperature, heater stays cold, temperature gauge rises unusually high, coolant level drops
The K10B injectors can gum up with poor fuel quality or extended storage. The result is rough running, increased consumption, and cold-start difficulties — especially with short-trip driving.
Symptoms: Rough running and unstable idle, increased fuel consumption, difficult cold start, engine stumble at low load
The K10B is considered a robust chain-drive engine capable of 200,000+ km. However, if oil change intervals are stretched, the chain tensioner can rattle. Fundamentally less problematic than Opel's own Z-series engines.
Symptoms: Metallic rattling or clattering on cold start that subsides once the engine warms up
The oil pressure switch is exposed and can develop a leak, with oil creeping into the wiring harness. Consequences can include engine management fault codes and, in rare cases, ECU damage.
Symptoms: Oil pressure warning light on despite correct oil level, engine management light comes on, oily wiring harness near the engine
Suzuki specifies a 105,000 km replacement interval for the NGK iridium spark plugs. If plugs are not replaced on schedule, misfires and increased fuel consumption result. Service history is rarely known on used vehicles.
Symptoms: Rough idle, misfires on cold start, slight power loss, increased fuel consumption
Vehicle Weaknesses 20
On Agila B models from 2011–2012 the lower joint of the steering intermediate shaft may not be correctly connected to the steering gear. In extreme cases steering can be lost completely. Recall action by Opel.
Corroded brake lines are flagged from the third MOT onwards. Older examples fail through insufficient operation of foot and handbrake. Typical MOT failure from approx. 7–10 years.
Recall for 2008 Agila B: possibly missing tear seam on the passenger airbag cover. The airbag may not deploy correctly when activated.
Recall 2011–2012: the lower joint of the steering intermediate shaft may not be correctly connected to the steering gear. In extreme cases, steering ability could be lost.
Rear brake calipers on the Agila B seize due to corroded guide pins. The caliper binds and causes uneven brake wear and pulling.
The spring seat joints and lower control arm bushings on the Agila B wear prematurely, causing knocking noises over bumps.
The gearbox on the Agila B requires regular oil changes. Neglected intervals lead to noisy gearboxes and premature bearing wear.
Surface corrosion on the underbody and sill areas is common on the Agila B, especially on vehicles that have not had underbody protection applied.
Vehicles with rear drum brakes: brake shoes and drums wear prematurely, especially with frequent short-trip driving. Shoe-to-drum contact area reduces if the handbrake cable is not properly adjusted.
The rear drum brakes show severe wear as early as 30,000–40,000 km. Most common MOT complaint. Brake shoes and drums must be renewed early.
With age, broken springs and worn shock absorbers become common. Control arm bushings wear prematurely. Suspension regularly flagged at inspection.
Early Agila B models show surface rust on the trunk lid and wheel arches within a few years. Underbody bolts and exhaust system rust quickly.
Coolant loss on the Agila B without visible external leaks — typically due to a porous thermostat housing or cylinder head gasket weeping.
The battery on the Agila B fails prematurely, especially with predominantly short-trip driving. Starting difficulties in winter are a typical symptom.
Electric window regulators fail through faulty motors, broken cables or worn guide rails. Mainly affects driver and passenger side.
The cabin blower resistor fails — the blower then only works on the highest speed. Known problem on Agila B and the related Suzuki Splash. Replacement part inexpensive.
Engaging reverse on the manual gearbox is frequently difficult. Design-related characteristic of the Suzuki gearbox without a permanent fix.
The Suzuki gearbox in the Agila B requires transmission oil changes every 45,000 km. With neglect, shifting becomes increasingly notchy and can cause expensive damage.
The rear window seal on the Agila B leaks and allows water to enter the boot area. The sealant compound degrades over time.
Rear silencer and mid box corrode reliably. A routine repair on older models past 120,000 km. Cheap replacement with aftermarket parts possible.
