All about the Audi A4 (B8)All about the 1.2 / 1.6 / 2.0 TDI CR (EA189) engine
The 2.0 TDI CR (EA189) engine was fitted to the Audi A4 (B8) (2007–2015). In the EU that is 79.1 % of all new cars of this generation.
Versions: 2.0, 2.0 143 hp, 2.0 177 hp, 2.0 150 hp, 2.0 136 hp, 2.0 120 hp, 2.0 170 hp.
The most expensive known risk is DPF clogging or faulty DPF pressure sensor: it usually appears at 80,000–200,000 km and costs €100–1,800 to fix.
✓ The faults of this engine were checked against sources (10/2026). Each item has at least two independent sources or an official recall or parts-maker technical note.
Signs: Power loss, limp mode, EGR fault codes (e.g. P0401), black smoke
Fix: Check EGR position and flow in live data; clean or replace the valve, and the cooler if it is blocked
Signs: DPF light, frequent or interrupted regenerations, limp mode; worse with short trips
Fix: First check the differential pressure sensor and its hoses, then soot and ash load; forced regeneration, cleaning or replacement; use low-ash VW 507.00 oil
Signs: Engine light with P2015, reduced power, sometimes limp mode
Fix: Clean the manifold and fit a linkage repair kit, or replace the manifold with flaps; adapt the flaps with a diagnostic tool
Signs: Engine light, reduced power or limp mode, codes P2563 / P2564
Fix: Check vacuum lines and the control valve, the crankcase pressure valve in the cylinder head cover (1.6 TDI) and the actuator with its position sensor; clean the vanes or replace the turbo if needed
Signs: Oil pressure warning, then sudden loss of oil pressure; the engine can be destroyed
Fix: Stop the engine at once if the oil pressure light comes on; on early engines fit the revised longer (100 mm) hex shaft preventively, e.g. with the timing belt
Signs: Hard starting, power loss, rail pressure codes; metal particles can reach the injectors
Fix: Replace the pump; if there is metal debris, also injectors, rail and lines, and flush the tank; check the fuel filter for metal at services
Signs: Harder starting, rough idle, smoke, higher fuel use, high return flow on the test
Fix: Return-flow (leak-off) test and check of injector coding; recondition or replace the faulty injectors
Signs: Coolant loss, coolant traces at the timing belt cover, temperature warning
Fix: Replace the pump together with the whole timing belt kit, even if the belt is not yet due
Signs: Applies to every EA189; after the update some owners report more EGR and DPF faults
Fix: Have a dealer check by VIN that the free update was done; the 24-month extra cover after the update has expired
Signs: Clunks and creaks over bumps, vague steering, uneven tyre wear.
Fix: Replace the worn upper/lower front arms (often as a set per side), check rear subframe bushes, then align the wheels.
Signs: Kickback through the wheel on rough roads or when braking, steering fluid loss, whining pump, car tugs to one side.
Fix: Find the leak; replace the high-pressure line or recondition/replace the rack, then align the wheels.
Signs: Wet carpet (often by the pedals), water running down the trim, MMI or other modules glitching or rebooting.
Fix: Clear sunroof and cowl drains, check the cowl trim and windscreen bonding (especially after a screen replacement), dry carpets and inspect modules.
Signs: Screen freezes or restarts, slow boot, touchpad or controls not responding.
Fix: Check battery condition and for water in the car first; a software update fixes many cases, otherwise repair the unit.
Signs: One door does not lock/unlock with the fob, door-open warning stays on, boot does not open electrically.
Fix: Read the door module codes; replace the lock unit of that door or the boot release.
Signs: No warning signs.
Fix: Check the VIN for the open recall; the dealer reprograms the airbag control unit free of charge.
Signs: Slipping, high bite point
Fix: Replace clutch kit
Signs: Rattle at idle, vibration pulling away
Fix: Replace with clutch
Signs: Judder pulling away, jerks, 'gearbox fault' limp mode
Fix: Fluid every 60,000 km; repair or exchange
Signs: Gearbox warning, odd or even gears (1-3-5 or 2-4-R) drop out, delayed or wrong shifts, limp mode or no drive
Fix: Diagnose with a dealer-level tester; repair the control unit / solenoids or fit a reconditioned mechatronic unit, change the oil and filter and run the adaptations
Signs: Delayed or harsh shifts
Fix: Fluid service, repair
Typical routine maintenance cost for 100,000 km: €2,400–5,750. Sum of the services and wear parts in the plan above (about 15,000 km a year, independent workshop), without faults.
