Audi A4
EA211evo with 110 kW for longitudinal installation. Fitted in A4/A5 from facelift onwards. Same technology as DPCA, adapted peripherals for the MLB platform.
Solid everyday engine — does its job
150 hp 1.5L for everyday use. Watch for known weak points.
Engine Weaknesses 5
The 1.5 TFSI EA211 Evo tends to elevated oil consumption of 0.5–1 litre per 1,000 km at higher mileages. Piston ring and crankcase ventilation problems are the cause.
Symptoms: Oil level drops noticeably between oil changes; blue smoke when accelerating is possible
The DADA gasoline particulate filter tends to clog with frequent short-trip use as the required regeneration temperature is not reached. Chemical cleaning is no longer sufficient from around 120,000 km.
Symptoms: Engine warning light, noticeable power reduction, increased fuel consumption
Carbon deposits and thermal load cause bearing failure or wastegate malfunction on the EA211 Evo turbocharger, especially on VTG variants and with frequent short-trip use.
Symptoms: Power loss, whistling or rattling under load, irregular boost pressure
The active cylinder deactivation (ACT) causes noticeable vibrations and hesitation when switching between 2- and 4-cylinder operation, especially with manual gearboxes during cold running.
Symptoms: Juddering or vibration when accelerating in 1st and 2nd gear, especially after cold start; occasional engine warning light
Despite direct injection, the DADA engine is prone to coking of the intake system and EGR valve, especially with long oil-change intervals or predominantly city driving.
Symptoms: Rough idle, increased fuel consumption, occasional fault messages for the mass air flow sensor
Vehicle Weaknesses 7
Defective coolant valves cause coolant loss that can silently lead to overheating. Temperature sensors and thermostat housing are a weak point from 60,000–100,000 km.
The rubber bushings in the upper control arms wear prematurely, in some cases from as early as 60,000–80,000 km. The issue is said to have been fixed only with the 2019 facelift.
Certain 19-inch tyre combinations on the B9 lead to premature wear on the inner flanks. The cause is a suspension setup not optimally tuned for larger wheels. Regular wheel alignment recommended.
The S tronic dual-clutch gearbox judders when pulling away and at low speeds. The mechatronics unit can become defective.
Water pump and thermostat housing typically fail between 60,000 and 170,000 km. A well-known weak point on the 2.0 TFSI and 2.0 TDI.
The S tronic dual-clutch gearbox exhibits a known juddering in D and R at idle that Audi classes as within the state of the art. Diesel variants may additionally creep.
The MMI infotainment system frequently exhibits Bluetooth connectivity problems in facelift models: choppy music playback, missed ringtones. Software updates do not always provide a permanent fix.
