Variant	Running cost per month	Median price	Listings	Fuel	Engine codes	Gearbox	Production years
1.6, 102 PS, 5-speed manual Research	€402	€1,600	101	Petrol		Manual (5)	2000–2003

Years: built 1996 to 2003. The facelift came in 2000. The S3 (1.8 T, 210 or 224 PS) is covered in the engine list.
The issues that matter: a broken TDI timing belt destroys the engine, clutch wear on manual cars, and rust on doors and roof edges.
Reliability: 3/5, because a snapped TDI timing belt is an engine loss and clutch and coil repairs cost real money.
DIY: 3/5, because belt, clutch and pump-injector jobs need a workshop, while window carriers and coils are simpler.
Prefer: 1.6 and 1.8 20V petrol cars with a service record, and TDI cars with proof of timing belt work.
Avoid: TDI cars with no timing belt proof, and 1.8 T cars with no coil or air mass meter work.

Timing belt: on a 1.9 TDI, ask for proof of timing belt work by 60,000 to 90,000 km. A bad result is no proof.
Pump-injector: on a 1.9 TDI pump-injector, ask for injector or pump-injector records. A bad result is no records on a high-mileage car.
Clutch: on a manual car, ask when the clutch was last replaced. A bad result is judder or slipping, or no record.
Coils: on a 1.8 T, listen for rough running and misfire at idle. A scanner shows misfire codes. A bad result is a misfire or no coil records.
Air mass meter: on a 1.8 T or S3, test for lost power under load. A scanner shows the fault codes. A bad result is loss of power.
Rust: check sills, door edges and the roof edge by hand. A bad result is bubbling paint or paint that breaks away.
Windows: test every window up and down. A bad result is a window that stops, moves slowly or drops.
