The B8-generation 2008 A4 introduced Audi's problematic 2.0T FSI engine (EA888 Gen 1) which suffers catastrophic oil consumption and timing chain issues, plus typical German luxury aging problems. The 3.2L V6 is more reliable but thirsty and has its own timing chain concerns.
2.0T Excessive Oil Consumption & Piston Ring Failure
Common · high severity
Typical onset: 60,000-120,000 mi
Symptoms: burning 1+ quart per 1,000 miles, blue smoke on startup or acceleration, fouled spark plugs, misfires, carbon buildup on intake valves
Fix: Piston rings wear prematurely due to design flaw; requires engine removal, full teardown, new pistons/rings, valve cleaning. 25-35 hours labor. Many owners opt for remanufactured long-block swap instead of rebuild.
Estimated cost: $6,000-10,000
Timing Chain Tensioner Failure (Both Engines)
Common · high severity
Typical onset: 80,000-150,000 mi
Symptoms: rattling on cold start that quiets after 5-10 seconds, check engine light with cam/crank correlation codes, complete failure causes catastrophic engine damage
Fix: Tensioner piston seals fail, losing hydraulic pressure. Requires timing chain, guides, tensioner, and often upper oil pan removal. 12-18 hours labor. On 2.0T this often coincides with oil consumption issues.
Estimated cost: $2,500-4,500
Direct Injection Carbon Buildup (2.0T)
Common · medium severity
Typical onset: 50,000-80,000 mi first cleaning needed
Symptoms: rough idle, hesitation on acceleration, misfires, reduced fuel economy, long cranking when cold
Fix: FSI engines have no fuel washing intake valves; carbon accumulates heavily. Requires walnut blasting intake ports with intake manifold removed. 4-6 hours labor. Needs repeating every 40,000-60,000 miles.
Estimated cost: $500-800
Water Pump & Thermostat Housing Leaks
Common · medium severity
Typical onset: 70,000-110,000 mi
Symptoms: coolant puddles under car, low coolant warning, overheating, steam from engine bay, plastic thermostat housing cracks are common
Fix: Both 2.0T and 3.2L use plastic-impeller water pumps and plastic thermostat housings that crack. Replace both together as preventive. 3-5 hours labor depending on access.
Estimated cost: $800-1,400
Multitronic CVT Transmission Failure (CVT models)
Occasional · high severity
Typical onset: 80,000-130,000 mi
Symptoms: shuddering during acceleration, slipping between ranges, whining noise, limp mode, complete failure to move
Fix: Multitronic CVT has poor reliability record; chain and clutch pack wear. Transmission fluid changes every 40k help but often fail regardless. Rebuild 18-22 hours, but most get remanufactured unit. Manual and DSG far more reliable.
Estimated cost: $4,500-7,000
Control Arm Bushings & Ball Joints
Common · low severity
Typical onset: 60,000-90,000 mi
Symptoms: clunking over bumps, wandering steering, uneven tire wear, vibration at highway speeds
Fix: Front lower control arms use pressed bushings that wear, causing play. Audi typically requires full control arm replacement rather than bushing service. 3-4 hours for both sides with alignment.
Estimated cost: $800-1,200
Coil Pack Failures (2.0T especially)
Occasional · low severity
Typical onset: 50,000-100,000 mi
Symptoms: misfires on specific cylinders, check engine light, rough running when wet, hesitation under load
Fix: Coil packs crack internally or suffer moisture intrusion. Easy DIY replacement. Always replace spark plugs simultaneously if carbon buildup present. 1-2 hours labor if paying shop.
Estimated cost: $400-700
Owner tips
Check service records for oil consumption complaints and any engine work—this is the deal-breaker item
2.0T engines: confirm timing chain service was done; listen carefully for cold-start rattle
Religiously change oil every 5,000 miles with 502.00-spec oil despite Audi's 10k interval—may slow piston wear
Carbon cleaning every 50k miles is mandatory maintenance on 2.0T, not optional
Manual or DSG transmissions only—avoid Multitronic CVT at all costs
Budget $1,500-2,500 annually for deferred maintenance catching up on these models
Avoid the 2.0T unless you find one with documented engine rebuild/replacement and immaculate service history; 3.2L V6 with manual is the only B8 A4 worth considering used, and even then budget heavily for German car entropy.

AIR BAGS:FRONTAL:PASSENGER SIDE:INFLATOR MODULE · 18V427000
2018-06-22 · EA15001
Volkswagen Group of America, Inc. (Volkswagen) is recalling certain 2005-2008 Audi A4 Sedan, A4 Avant, S4 Avant and S4 Sedan, 2007-2008 RS4 Sedan, 2004 RS4 Cabriolet, 2007-2009 A4 Cabriolet and S4 Cabriolet, 2005-2011 A6 Sedan, 2006-2011 A6 Avant, and 2007-2011 S6 Sedan vehicles. These vehicles are equipped with certain air bag inflators assembled as part of the passenger frontal air bag modules used as original equipment or replacement equipment. In the event of a crash necessitating deployment of the passenger frontal air bag, these inflators may explode due to propellant degradation occurring after long-term exposure to absolute humidity and temperature cycling.
Consequence: An inflator explosion may result in sharp metal fragments striking the driver or other occupants resulting in serious injury or death.
Remedy: Audi has notified owners, and dealers will replace the passenger frontal air bag with an alternate remedy part, free of charge. The recall began June 29, 2018. Owners may contact Audi customer service at 1-800-253-2834. Volkswagen's number for this recall is 69R7. Note: This recall supersedes recalls 16V382, 17V032 and 18V004 and includes vehicles that may have had their air bag previously replaced under one of those campaigns.
