VW eHybrid

The DGEB PHEV in the Tarraco (245 hp system output) shares the known HV coolant circuit problem of the VAG PHEV platform. Defective heat exchanger between A/C and HV cooling causes coolant loss and pressure issues. Repair approx. 400 euros plus fitting.

Symptoms: Red warning triangle, hybrid fault message, vehicle will not start, HV coolant reservoir level dropped

Individual HV battery cells can fail prematurely and deactivate the battery. Skoda started voluntary service action 93P7 in September 2022. Primarily model year 2021.

Symptoms: Sudden power loss, vehicle unresponsive to throttle for 2–3 seconds, HV battery warning, vehicle must be towed

In the DGEB PHEV Tarraco there is no alternator. The 12V battery is supplied through the HV system. With purely electric use and no regular combustion engine operating phases, the 12V battery can be drained.

Symptoms: Keyless entry failure, starting difficulties, 12V battery warning, pre-conditioning not working

The Tarraco with DGEB occasionally shows hybrid ECU errors leading to warnings and electric drive failure. Software update or ECU replacement required. HV work only at certified Level 3 workshops.

Symptoms: Hybrid drive drops out, fault message on display, vehicle drives in combustion-only mode

The 12V starter battery drains through faulty control unit software (BEM/gateway), especially on early vehicles 2020–2021. Multiple system errors are triggered by undervoltage.

Symptoms: Vehicle activates itself overnight, numerous simultaneous ADAS errors, vehicle will not start

After the 8-year/160,000-km warranty expires, HV battery replacement costs approx. 12,000 euros at the Skoda dealer. Real long-term degradation data is not yet available.

Symptoms: Noticeably reduced electric range (below 70% of original range), battery capacity display declining

Approximately 56,000 Golf 8 vehicles were recalled because the automatic emergency call (eCall) did not function reliably due to a software fault in the OCU3 control unit. Around 26,000 vehicles in Germany were affected.

On Golf 8 vehicles from model years 2020–2022, a loose engine cover can come into contact with hot engine parts and melt, causing fire risk in the engine bay. VW carried out a recall.

On the Golf 8 (CD), the A/C compressor centre bolt works loose on its own. Debris enters the refrigerant circuit and damages the entire system. In addition to the compressor, the dryer and expansion valve must also be replaced.

The MIB3 infotainment system in the Golf 8 frequently crashes or shows a black screen. Navigation, reversing camera and driver assistance systems fail as a result. Early production years 2019–2021 are particularly affected.

The front camera on the Golf 8, responsible for Travel Assist, Lane Assist, Front Assist and ACC, frequently fails and must be replaced. Software updates are often insufficient — a hardware defect is usually the cause.

The Golf 8 suffers from excessive quiescent current due to extensive electronics and software bugs, prematurely draining the starter battery. The many networked control units do not reliably enter sleep mode.

The electronic parking brake on the Golf 8 shows faults in conjunction with the shift-by-wire gearbox. Error messages and Auto-Hold failures occur; in some cases the brake locks when pulling away.

The DSG gearbox in the Golf 8 shows software and hardware-related shift misfires and juddering. The tight software integration with the MQB-EVO vehicle network causes gearbox failures during system errors.
