Audi A4: EA888 Gen3 2.0 TFSI piston ring oil consumption

The EA888 Gen3 2.0 TFSI engine (DETA/DKNA codes) suffers chronic piston ring failure allowing engine oil to enter the combustion chamber. Affected vehicles can consume 1 litre or more of oil per 1,000 km. Audi issued an extended warranty campaign covering this defect — the same root cause as the well-publicised Volkswagen Mk7 Golf EA888 oil-consumption campaign. If unaddressed, continued oil burning damages the catalytic converter and eventually causes engine failure. Piston ring replacement or short-block replacement is typically required.

• Excessive oil consumption exceeding 1 litre per 1,000 km
• Blue-grey smoke from exhaust at cold start or under hard acceleration
• Oil level warning light illuminating between scheduled service intervals
• Oil-fouled or oil-coated spark plugs
• Strong burning oil smell from engine bay after spirited driving

1. 1

   Check dipstick oil level at purchase and compare after a 20-minute test drive under load.

2. 2

   Inspect exhaust pipe outlet for blue oily residue.

3. 3

   Pull spark plugs and check for oil contamination.

4. 4

   Ask seller for any oil top-up receipts or records between service intervals.

5. 5

   Scan for catalyst efficiency fault codes that often accompany chronic oil burning.

Parts involved: Catalytic converter.

$4,000 to $12,000 at New Zealand independent workshop rates. That is for this job on its own, not for the car.

An estimate, in NZD, for the repair as normally carried out. What a specific car costs depends on which part has failed and what it damaged on the way — treat this as the floor for a negotiation, not a quote.

• “How often does the engine oil need to be topped up between scheduled services?”
• “Has the Audi extended warranty campaign for EA888 oil consumption been applied to this vehicle?”
• “Have the spark plugs been replaced recently, and were they fouled with oil deposits when removed?”

The failure described above is documented in published sources — owner forums, technical service bulletins, recall notices and workshop write-ups — held in our fault database. The inspection instructions and the cost estimate are KickTyres’ own interpretation of them, and it is a starting point for an inspection rather than a manufacturer statement.
