Audi 50 TFSI e
EA888 evo4 plug-in hybrid with 195 kW combustion engine and 105 kW electric motor. Further development of the DLGA with slightly higher engine output and a larger 17.9 kWh battery.
Facelift polishes the concept, changes nothing fundamental
Facelift update with larger battery (up to 61 km WLTP) and revised styling. Sensible for commuters with a home charger, still uninteresting for enthusiasts.
Engine Weaknesses 9
The high-voltage battery in DRYA vehicles is affected by the Samsung SDI cell module defect. Overheating can occur during charging. KBA recall 93AD, approximately 17,000 vehicles in Germany.
Symptoms: High-voltage battery warning; charging stops without apparent reason; Audi recommends avoiding external charging until software update.
The facelift variant's hybrid gearbox shares its fundamental design with the predecessor. Gearbox failures on Q5 and A7 55 TFSI e have been documented from around 20,000–80,000 km.
Symptoms: Juddering on pull-away; shifting problems between gears; gearbox emergency programme active; fault message in instrument cluster.
Despite improvements over the evo3, the EA888 evo4 timing chain can show stretch from around 110,000–140,000 km with poor oil maintenance. Rattling on cold start is the first warning.
Symptoms: Metallic rattling from engine bay on cold start; fault codes P0016/P0017; power fluctuations.
Known weak point of the TFSI e charging infrastructure: charging port microswitch fails from moisture, the on-board charger may be defective or deliver half its rated power.
Symptoms: Warning 'charging system locking fault'; charging fails; vehicle does not charge at public stations; charging time doubles.
The larger 17.9-kWh battery is subject to the same ageing mechanisms. Within the 8-year warranty, 70% capacity is defined as non-defective.
Symptoms: Electric range below 35 km instead of the original 45+ km; below 20 km in winter.
In PHEV mode with empty high-voltage battery on pure electric city driving, the 12V battery can discharge. Inadequately protected in early software versions.
Symptoms: Sudden 'battery weak' warning after pure electric driving; vehicle fails to start.
The longitudinally mounted EA888 water pump is prone to leaking. Coolant loss and in severe cases coolant ingestion into the vacuum system can cause secondary damage.
Symptoms: Dropping coolant level without external leak; overheating warning; fault code P0299.
Despite optimisations the direct-injection principle remains. Without port injection, deposits accumulate on intake valves — aggravated by frequent EV-mode operation with rare combustion engine runs.
Symptoms: Cold-start judder and rough idle; power loss below 2,000 rpm; increased fuel consumption in hybrid mode.
With predominantly regenerative braking, the rear brake discs get little mechanical cleaning. Road salt in winter accelerates corrosion considerably — TÜV rejection possible.
Symptoms: Visible rust on brake discs; grinding noise on first brake application; inspection rejection.
Vehicle Weaknesses 5
KBA recall: stress corrosion cracking can cause elevated play between the control arm and wheel carrier. Affects build years 2019–2021. Free replacement at dealer.
Recall for Q5 FY (production July 2018 to March 2019): faulty brake master cylinders increase stopping distance. Free replacement programme through Audi.
The Haldex rear differential suffers from oil contamination by clutch debris when maintenance is neglected. A differential oil change clears the symptoms. Neglect risks differential damage.
Brake callipers seize especially after prolonged standing. Rear axle callipers are most affected. MOT reports list brake defects as a frequent fault.
Early FY models show MMI faults: faulty Google Earth view, Audi Connect dropouts and failure of the 360-degree camera. Audi has issued service actions and firmware updates.
