Skoda Superb
Third generation EA888 with 1.8 litres and 132 kW. Improved timing chain drive versus Gen2 — less prone to chain stretch. Combination of direct and port injection significantly reduces valve carbon build-up. Main weak points: cooling system (water pump integrated with thermostat, frequent failures), timing chain at high mileage, occasional head gasket issues.
TSI estate with class
The 1.8 TSI in the Superb Combi: adequately powered, comfortable with DSG. A solid all-rounder.
Engine Weaknesses 3
Thermostat is integrated into the water pump and not available separately. Coolant loss from a leaking pump or thermostat housing typical from 60,000–80,000 km. Repeated failures documented.
Symptoms: Coolant level drops without visible leak, coolant puddles under vehicle, engine temperature rises too slowly (thermostat stuck open) or overheats (pump failure).
Gen3 has an improved chain tensioner versus Gen2 but remains susceptible at high mileage (from 100,000 km) or after extended oil change intervals. ECU corrections mask the issue until failure without a warning light.
Symptoms: Metallic rattling on cold start that diminishes once warm. Engine may set ignition timing codes. In the worst case the chain jumps.
The cam follower on the high-pressure pump can wear with insufficient lubrication. Metal particles contaminate the oil circuit. Regular inspection every 40,000 km recommended.
Symptoms: Starting problems, rough engine running, metal particles in oil at oil change, noises from high-pressure pump.
Vehicle Weaknesses 8
On the 2.0 TDI (Euro 6) the AdBlue injection system fails: injector, connecting lines or sensors give out. Crystallisation blocks the lines. Sensor faults often require a complete tank replacement costing €2,500–3,000. Engine will not start.
The DQ381 dual-clutch gearbox can develop bearing damage from approximately 80,000 km, leading to metallic noises and in the worst case gearbox failure.
The optional DCC dampers start leaking oil from as little as 70,000–80,000 km. The MOT classes leaking dampers as a significant fault. Skoda frequently declines warranty. Two new front DCC dampers cost €950–1,800.
The rear axle springs break through material fatigue despite normal driving. Affects vehicles from approximately 80,000 km. A failed MOT and tyre damage risk result. Both springs should always be replaced in pairs.
ACC and Lane Assist deactivate with fault messages for no apparent reason. The air quality sensor is also a frequent trigger for subsequent fault codes. The problem affects the entire MQB platform and is usually resolved by a software update.
Brake discs on the Superb III are regularly reported as an MOT fault, particularly on high-mileage fleet vehicles. The high vehicle weight and frequent motorway use accelerate wear on the front discs.
The lower door edges show first rust blistering from approximately 5 years, particularly on the rear doors. Stone chip damage and inadequate cavity sealing are the cause.
The servo motors of the dual-zone climate control can fail, causing one side to blow only hot or only cold air. The temperature sensor or the servo motor itself is commonly affected.
Reports & Tests
The current Superb also shows elevated fault rates at the MOT, due to intensive fleet use at high mileages. Suspension and brakes suffer particularly.
The Superb is one of the more reliable models in the upper mid-size class and achieves above-average results in the breakdown statistics for its segment.
