The B8-generation Audi A4 with the 2.0 TFSI (EA888) is a refined executive sedan that sold in large numbers across Europe. The turbocharged four-cylinder is smooth and reasonably efficient, and parts availability is excellent thanks to wide VAG platform sharing. Early models (2008-2012) with the EA888 Gen 2 (CDNB/CDNC) carry a reputation for excessive oil consumption and timing chain tensioner problems. The B8.5 facelift arrived in February 2012, cars built from late 2012 received revised pistons and tensioners that largely resolved both issues, and the 225 hp CNCD of the EA888 Gen 3 followed in 2013.· more· less

Faulty piston rings allow oil to burn in combustion chambers, mainly affecting 2008-2012 models · more· less
The EA888 Gen 2 engine (CDNB and CDNC) used in 2008-2012 B8 models is well known for excessive oil consumption, with some owners reporting 1 litre per 1,000 km or worse. The root cause is undersized piston ring land widths and ring tension that allows oil past the pistons. Audi acknowledged the issue with a TSB: the first-stage fix involves a new crankcase breather and ECU software update (€300-500). If consumption remains above 0.5L/1,000 km, the second-stage repair requires new pistons, rings, and connecting rods — essentially an engine strip-down costing €2,500-4,500 depending on whether cylinder bore damage has occurred. Models built from late 2012 onwards received revised 21mm wrist pin pistons that largely resolved the problem. When buying a pre-2013 car, always perform an oil consumption test over at least 2,000 km.
Timing chain tensioner failure (pre-2012)
up to €3,0002 of 7
Plastic tensioner loses hydraulic pressure overnight, causing chain rattle and potential engine damage · more· less
The EA888 Gen 2 timing chain tensioner (located at the back of the engine) is known to fail, allowing the chain to slacken. The telltale symptom is a rattling noise for a few seconds on cold start. If ignored, the chain can skip teeth and cause valve-to-piston contact — a catastrophic failure requiring engine replacement. This issue predominantly affects 2008-2011 models. Audi updated the tensioner part number multiple times. Replacement involves removing the engine or at minimum the gearbox for access, with total costs of €1,200-1,800 at an independent specialist or €2,000-3,000 at a dealer. Cars built from late 2012 onwards received a revised tensioner design with significantly lower failure rates.
Water pump failure
up to €1,2003 of 7
Plastic water pump housing cracks from heat cycling, causing coolant leaks · more· less
The OEM water pump uses a plastic housing that is prone to cracking and leaking, typically between 60,000 and 120,000 km. This was widespread enough to trigger a United States class-action lawsuit covering 2009-2014 models. The separate European campaign on 2013-2016 cars concerned the additional electric coolant pump, which could block or overheat electrically, and was remedied first with software and later by replacing that pump; it is not the mechanical plastic housing described here. Symptoms include coolant warning light, visible leaks around the water pump area, and poor heater performance. The recommended fix is to replace with an aftermarket aluminium water pump housing to prevent recurrence. Parts cost €150-300 for an upgraded unit; total repair runs €500-800 at independent shops or €800-1,200 at dealers. This issue can affect both early and late B8 models.
PCV valve diaphragm failure
up to €5004 of 7
Internal diaphragm tears, causing vacuum leak, rough idle, and whistling noise · more· less
The positive crankcase ventilation (PCV) valve assembly sits on top of the cylinder head and contains a rubber diaphragm that tears over time. When it fails, the engine develops a vacuum leak resulting in rough idle, whistling noise at idle, and possible lean fault codes. The PCV assembly costs €80-150 for the part and is a relatively straightforward 1-2 hour job. Audi has revised this part several times — always install the latest revision. The PCV failure can also contribute to increased oil consumption, so replacing it is often the first diagnostic step when oil consumption rises.
Carbon buildup on intake valves
up to €9005 of 7
Direct injection allows oil vapour deposits to bake onto intake valves, reducing airflow · more· less
Like all direct-injection petrol engines, the 2.0 TFSI is susceptible to carbon deposits accumulating on the intake valves. Because fuel is injected directly into the cylinder rather than over the valves, there is no fuel wash to keep them clean. Symptoms emerge gradually after 60,000-100,000 km: rough idle, hesitation under load, misfires, and reduced power. The only effective fix is walnut shell blasting — a specialist removes the intake manifold and media-blasts the valves clean. Cost is €400-600 at independent shops or €700-900 at dealers. Preventive measures include regular Italian tunes (sustained highway driving) and catching oil leaks from the PCV system early.
CVT chain and clutch packs wear prematurely, causing jerking, slipping, and eventual failure · more· less
The Multitronic (0AW) CVT, available on front-wheel-drive B8 models, has a troubled reliability record. Common failure points include worn friction plates, faulty solenoids, and chain slippage. Problems typically appear between 100,000-150,000 km, often manifesting as jerky acceleration from standstill, hesitation, or complete loss of drive. Regular transmission fluid changes every 60,000 km are critical and are what Audi's own A4 B8 service table specifies, but they are often neglected because owners assume the unit is sealed. Repair costs for mechatronic or clutch pack work run €2,000-3,500, while a full transmission replacement can reach €4,000-5,000. Manual and S tronic (quattro) models do not have this issue and are strongly preferred.
High-pressure fuel pump (HPFP) failure
up to €1,5007 of 7
Cam-driven fuel pump fails, causing loss of power and stalling · more· less
The high-pressure fuel pump can fail without much warning, causing the engine to stall and refuse to restart. Diagnosis shows low fuel rail pressure (fault code P0087). This issue is less common than oil consumption or timing chain problems but can occur on any model year. When the HPFP fails, the entire fuel system should be inspected for metal debris before installing a new pump. Replacement costs €600-900 at independent shops or €1,000-1,500 at dealers including parts and labour.
Reliable platform with known engine-specific weak points
The Audi A4 B8 2.0 TFSI is fundamentally a solid car, but the early EA888 Gen 2 engine (2008-2012) has well-documented oil consumption and timing chain tensioner issues that can be expensive to rectify. The B8.5 facelift arrived in February 2012, and it is the revised internals fitted from late 2012 that addressed both concerns and made the later cars significantly more reliable. Regardless of model year, avoid the Multitronic CVT if possible — manual and S tronic transmissions have a much better track record. Water pump failure and carbon buildup affect all years but are manageable with proactive maintenance.
Service history
Complete Audi dealer or specialist records essential. Verify oil change intervals — short intervals (10,000 km or less) are a positive sign on these engines.
Tires
Check tread depth, age (date codes), and uneven wear. Uneven front tire wear can indicate worn control arm bushings.
Cold start
Must start the engine completely cold. Listen carefully for any rattling noise in the first 30 seconds — this is the critical timing chain tensioner test.
Test drive
Drive for at least 20 minutes including varied speeds. Pay attention to engine smoothness, gearbox behaviour, and any warning lights.
Specific for this vehicle
Cold start rattle test (timing chain)
Arrive when the engine is fully cold. Start the engine and listen for a distinctive rattle or maraca-like noise in the first 30 seconds. Any rattle indicates a worn timing chain tensioner — budget €1,200-3,000 for repair.
Oil level and consumption history
Check oil level on the dipstick. Ask the seller about oil consumption between services. On pre-2013 models, request documentation of any oil consumption tests or piston ring replacement.
Check for coolant leaks around water pump
Inspect the area around the water pump housing for coolant residue or staining. Check coolant level in the expansion tank. Low coolant or visible leaks indicate water pump failure.
+ 4 more checksShow less
Transmission behaviour (Multitronic models)
If the car has a Multitronic CVT, test acceleration from standstill repeatedly. Feel for jerking, hesitation, or RPM dropping. Ask for transmission fluid change records. If no records exist, budget for a fluid change immediately.
Check for PCV valve whistle at idle
With the engine idling, listen for a whistling or squealing noise from the top of the engine. Remove the oil filler cap briefly — if the engine stalls, the PCV diaphragm has likely failed.
Verify build date for oil consumption risk
Check the build date on the door jamb sticker. Cars built before late 2012 are in the high-risk window for oil consumption. Cars built from 2013 onwards have revised pistons.
Front suspension clunking
Drive over speed bumps slowly and listen for clunks from the front. The B8 uses multi-link front suspension with aluminium control arms that wear — full front end rebuild costs €600-1,200.
Recalls and Technical Service Bulletins
Turbocharger coolant supply line may leak (European campaign 21C5, 2.0 TFSI)Critical - verify completed
Additional electric coolant pump blockage causing overheating (2013-2016 models with 2.0 TFSI)Verify completed
Takata airbag inflator (various model years)Verify completed
Contact an Audi dealer with the VIN to verify all recalls have been completed. The 21C5 turbocharger coolant line campaign and the electric coolant pump campaign are the important ones for the 2.0 TFSI. Ask separately whether the oil consumption repair (crankcase breather and, where needed, piston ring replacement) was performed on cars built before late 2012. The crankcase ventilation campaign and the power steering hose action are a North American emissions measure and a technical service bulletin respectively, not European recalls.
Warranty Status
Factory warranty (2 years)Expired on all B8 models
Rust perforation warranty (12 years)May still apply to late B8.5 models (built 2014-2015)
Extended warrantyAvailable through Audi dealers and third-party providers
All Audi A4 B8 models are outside their original 2-year factory warranty. The 12-year rust perforation warranty may still cover late B8.5 models built in 2014-2015. The extended 8-year/80,000-mile oil consumption warranty often quoted for this engine was an Audi of America programme and is not European coverage.
