Skoda Superb
The 1.8L TSI (EA888 Gen2, CDAA) became notorious for its oil consumption — a design fault with undersized oil control rings that VAG only fully resolved later. The timing chain was revised five times (last version March 2012), indicating acknowledged design weaknesses. Cooling system (thermostat/water pump) is a further weak point. With piston ring repair and regular oil maintenance the engine remains long-lived.
Base TSI estate
The weaker 1.8 TSI in the Superb Combi: moves along solidly, doesn't inspire.
Engine Weaknesses 4
EA888 Gen2 CDAA engines were fitted from factory with overly thin oil control rings. From around 50,000–100,000 km consumption rises to 1–2 L/1,000 km. Cylinder bores can suffer secondary damage.
Symptoms: Frequent oil top-up between services (up to 3 L), blueish exhaust smoke under load, burning oil smell.
VAG revised the chain tensioner for the CDAA five times up to March 2012. Despite the revisions, chain damage appears from 70,000–100,000 km. A jumped chain risks severe engine damage.
Symptoms: Metallic rattling on cold start, rough idle, engine check light, in the worst case sudden engine failure.
The water pump and thermostat housing of the EA888 Gen2 are known weak points. Coolant loss and overheating risk typically appear from 100,000 km. Removal is time-consuming (approx. 3 hours).
Symptoms: Coolant level drops without visible leak, temperature gauge rises irregularly, coolant smell in engine bay.
The high-pressure fuel pump on the EA888 Gen2 can fail spontaneously and in the worst case release metal particles into the fuel circuit, damaging injectors, rail and lines.
Symptoms: Poor starting behaviour, engine stuttering especially on cold start, fault code 'rail pressure too low', in extreme cases engine will no longer start.
Vehicle Weaknesses 8
The mechatronic unit of the DSG gearbox (DQ250) can develop faults from approximately 100,000 km. Irregular gear changes and gearbox limp-home mode result.
Suspension springs break preferentially at the front axle, often without warning. According to TÜV reports one of the most frequent fault items on the Superb II. Significantly increased risk from approximately 100,000 km and 8 years.
The BCM controls the windscreen wipers, lighting, central locking and comfort functions. The typical failure pattern is a gradual loss of individual functions through to a total failure. Repair requires coding at a dealer.
Sills and rear wheel arches are prone to hidden rust beneath the protective coating. Corrosion begins from the inside and only becomes visible when blistering pushes through the paint. The tailgate and door fold areas are also at risk.
When the air conditioning compressor fails mechanically it seizes and distributes metal swarf throughout the entire refrigerant circuit. Repair then requires a full circuit flush plus drier and expansion valve replacement. The compressor alone costs approximately €400.
The electromechanical power steering develops a knocking noise when steering, particularly at low speeds. Wear of the steering rack mounting is a common cause.
The wiring harness breaks in the door hinge area through repeated bending movements. Mainly affects the driver's door and on the Superb the Twindoor tailgate. Cheap plastic sheathing without a coiled protective sleeve promotes failure.
The handbrake cables corrode inside their sleeves and become stiff or freeze in winter. Particularly affects vehicles in salty environments.
Reports & Tests
The second-generation Superb performs worse than the class average at the MOT inspection. Springs, dampers and the braking system are the biggest weak points.
