All about the Audi A5 (8T)All about the 1.8 / 2.0 TSI / TFSI (EA888) engine
The 1.8 / 2.0 TSI / TFSI (EA888) engine was fitted to the Audi A5 (8T) (2007–2016). In the EU that is 25.9 % of all new cars of this generation.
Versions: 2.0, 1.8 170 hp.
The most expensive known risk is turbo wastegate actuator wear (boost faults, limp mode): it usually appears at 80,000–200,000 km and costs €300–1,800 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: 1 L or more per 1,000 km, blue smoke, oily spark plugs; running low on oil can damage the chain and bearings
Fix: Rule out PCV and turbo first, then a measured consumption test; fit revised pistons and rings and renew the timing chain and tensioner at the same time
Signs: Rattle for a few seconds after a cold start, codes P0016 / P0017; a chain that jumps bends the valves
Fix: Check chain stretch in live data; fit the revised tensioner 06K109467K and, if the chain is stretched, the chain, guides and gears as a set
Signs: Oil pressure warning at various revs, rattle from the lower front of the engine
Fix: Stop the engine; measure oil pressure, check the oil pickup screen, the lower chain with its tensioner and guide, and the balance shafts; replace as a set
Signs: Coolant loss, coolant smell, fluctuating temperature gauge, slow warm-up or overheating warning
Fix: Find the leak with UV dye or a pressure test; replace the pump and thermostat module as one unit
Signs: Rough idle, misfires when cold, power loss, higher fuel use
Fix: Inspect the valves with an endoscope; clean the intake ports (walnut blasting or by hand)
Signs: Engine light with P2015, rough idle, whistling (vacuum leak) if the linkage pops off
Fix: Check the linkage and stops and clean off carbon; replace the intake manifold (latest version) and adapt the flaps
Signs: Whistle or hiss at idle, rough idle, lean codes (P0171), higher oil use, oil leaks at seals
Fix: Check fuel trims in live data; replace the PCV valve / oil separator
Signs: Power loss, boost pressure codes (e.g. P0299), limp mode
Fix: Compare set and actual boost in live data to rule out leaks; repair or replace the actuator, or the turbo if the wastegate itself is worn
Signs: Knocking, vague steering, uneven tyre wear
Fix: Replace the arm kit (8 arms)
Signs: Missing pixels in the display
Fix: Repair the cluster
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: Knock or jerk when shifting down into 3rd or 2nd in traffic, a pause of 1-3 seconds before the car pulls away
Fix: Ask the dealer for the latest gearbox software, change the oil and filter and reset the adaptations; if it persists, have the mechatronic checked
Signs: Delayed or harsh shifts
Fix: Fluid service, repair
Typical routine maintenance cost for 100,000 km: €2,200–4,950. Sum of the services and wear parts in the plan above (about 15,000 km a year, independent workshop), without faults.
