奧迪 TT 嘅常見問題會因代數、引擎同波箱而有差別。睇二手車時可重點檢查偈油消耗或滲漏、水泵及節溫器外殼漏水、S tronic 轉波異常、quattro／Haldex 保養紀錄、懸掛損耗同電子故障；Roadster 仲要試清楚電動軟篷同去水位。
The Audi TT’s common issues vary by generation, engine and gearbox, so the service history matters more than the badge alone. On older 1.8T cars, check the timing-belt and water-pump history, ignition coils, instrument-cluster display, suspension bushes and quattro/Haldex maintenance. Some 2.0 TFSI versions may suffer from excessive oil use, oil leaks or cooling-system faults; the water pump and thermostat housing are sensible inspection points. With S tronic-equipped cars, look for hesitation, harsh engagement, warning lights or missed gearbox-fluid servicing, as clutch or mechatronic repairs can be costly. Magnetic Ride dampers, where fitted, should be checked for leakage and warning messages. On the TT Roadster, test the roof several times and inspect the seals, drain channels and cabin for dampness. Before buying, arrange a diagnostic scan and a cold-start inspection, then confirm the exact engine code and maintenance requirements with an Audi specialist.
奧迪 TT 唔同代數嘅問題唔完全一樣，車齡同保養紀錄往往比表面車況更重要。較早期 1.8T 車款要留意正時皮帶及水泵有冇按時更換、點火線圈、儀錶顯示、懸掛膠套，以及 quattro／Haldex 系統有冇保養紀錄。部分 2.0 TFSI 車款可能出現偈油消耗、滲油或冷卻系統漏水，水泵同節溫器外殼係驗車時應重點查看嘅位置。配 S tronic 嘅車要試清楚起步有冇震動、入 D 或 R 有冇延遲、轉波係咪頓挫，同時核對波箱油保養；離合器或機電控制單元維修費可以較高。配備 Magnetic Ride 嘅版本亦應檢查避震有冇漏油或故障提示。Roadster 要反覆測試開篷、關篷，並檢查膠邊、去水槽同車廂有冇入水或霉味。買之前最好做冷車啟動、電腦診斷同上架檢查，再按引擎編號確認實際保養要求。
