Audi A4

Digest from the reviews

Based on transcripts of 3 reviews

• •All 3 reviewed transcripts name the pre-2011 1.8/2.0 TFSI as the B8's sore spot: oil burn through the piston group (figures of 1.5 to 2+ L/1,000 km are quoted) and timing chains stretching by 50-100k km — both were fixed under warranty (new pistons, modernised tensioner); the post-facelift third-gen engines are called largely cured, though thermostat and water-pump leaks remain.
• •The diesels are the consensus pick of all 3: the 2.0 TDI is 'the peak of reliability, especially to 200k km' — budget piezo injectors (~$300 apiece, 200-300k km life depending on fuel), a cam belt at 90-120k km real-world (the 180k regulation is called optimistic), and after 250k km replace the cheap oil-pump hex drive before it kills the turbo and engine.
• •On gearboxes the 3 reviews agree on the hierarchy: manual and the rare ZF tiptronic (3.0 TDI/3.2 only; fluid every 60k km gives 200-250k) are the safe ones — though diesel manuals eat a ~$600 dual-mass flywheel by 150-200k km; the S-tronic's mechatronics is the known weak point (fluid every 30-35k km, dealer-scanner check before buying is called mandatory).
• •The Multitronic CVT (every FWD car, with the 1.8 TFSI the bulk of ads) divides the reviewers only in tone: average ~150k km in town, 50-300k depending on driving style — jerks, vibration around 50-60 km/h or floating revs disqualify a car, any CVT failure means a tow truck, and a control-unit replacement alone is quoted at $1,000+.
• •Suspension and body: across the 3 reviews the chassis lives ~100-120k km between visits, but front lower ball joints knock by ~60-80k and front hub bearings go at ~50-70k; the body itself is calm — chips don't bloom — while headlights 'vacuum' dust via their ventilation (a foam filter fixes it) and post-facelift LED units lose single diodes (independent repair exists, skip the whole-unit quote).
