Reliability, common problems and owner reviews for the Audi A3 1.8 TFSI 160hp (BYT / CDAA, EA888). Check this before you buy used.
Lovely to drive, but the EA888 1.8 TSI is notorious for heavy oil consumption (thin piston rings) plus timing-chain stretch and the HPFP cam follower. A low-oil-use, chain-checked example is great; an unchecked one is a gamble.

This is the same physical engine (BZB) sold under different names across brands. Reliability is broadly shared — cross-check these:
Known Issues
Thin oil-control rings cause heavy oil burning, rising with mileage (up to ~2L/1,000km in bad cases).
Fix / Workaround: Check consumption before buying; revised pistons/rings fix it (major job). Keep oil topped.
Repair cost: €1500–€3000
Typically appears after: 100,000 km
Chain stretches ~100,000 km; early tensioner can let it jump.
