Skoda Superb
The 1.5 TSI eTEC (EA211 evo) with 48V mild hybrid system is a modern, efficient drivetrain. Cylinder deactivation (ACT) can cause rough running at part load on some vehicles. The 48V system is relatively new; long-term durability data for the belt-starter-generator is still limited.
MHEV base in the new Superb
110 kW in the 1.6-tonne Superb IV: the engine is too weak for this car. Frugal, but gutless.

The 48V mild hybrid system with belt-starter-generator (BSG) is a newer technology; long-term experience is limited. If it fails, repair costs are high since the system is closely integrated with the engine and electrical system.
Symptoms: 48V electrical system fault message, restricted start-stop function, reduced boost when pulling away
Below 800 rpm with high-current consumers active (seat heating, air conditioning), severe torque loss occurred. Affects manual gearbox variants from May–June 2019.
Symptoms: Sudden torque loss when pulling away with heating or air conditioning active
Active cylinder deactivation (ACT) causes noticeable juddering at low revs and in part-load operation. Software updates have only partially resolved the issue.
Symptoms: Noticeable juddering on throttle lift or at low revs, rough running in city traffic
Some engines show elevated oil consumption caused by piston rings or a faulty crankcase ventilation valve. Turbocharger shaft seals are less frequently affected.
Symptoms: Blue smoke when revving, dropping oil level, occasional blue haze at full load
Vehicle Weaknesses 6
The passenger airbag gas generator can burst on deployment and propel metal fragments into the interior. KBA recall from July 2025, airbag replaced free of charge. Fabia IV also affected.
All camera-based assistance systems fail simultaneously and report themselves as unavailable. The cause is a recognition problem with the windscreen camera. Skoda is developing a software update. Problems occur from as little as ~4,000 km.
The DCC adaptive dampers display fault messages in the on-board computer and switch to standard mode. Software errors or defective damper sensors are common causes.
The MIB4 infotainment system switches itself on when approaching the vehicle, freezes or becomes unresponsive. The KESSY system sporadically fails to unlock all doors. Software updates only partially resolve the problems.
The fuel filler flap sits crooked in the bodywork and dealers say it is within tolerance. The tank ventilation does not work reliably: the tank only takes 50–55 litres despite the gauge reading empty, requiring slow refuelling.
The Matrix LED headlights fog on the inside, particularly in damp weather and with temperature changes. Leaking ventilation membranes are a common cause.
