TSI is a range of turbocharged engines with direct petrol injection, produced by the German Volkswagen Group. The first TSI engine had a 1.4 litre capacity and was first presented in 2005 on the Golf GT Mk5. It was highly praised by experts and won the “Best New Engine” award in the prestigious “International Engine of the Year” competition. Today, models from such makes as Volkswagen, SEAT, and Škoda can be equipped with TSI engines. These engines develop high output and torque despite their relatively low capacity. They are characterised by fuel economy.
Features
TSI engines have 4 cylinders with 8 or 16 valves. The engine block can be made of cast iron or aluminium. The cylinder head is always aluminium. The engine can be turbocharged or twincharged. In the twincharged version, the engine has both an exhaust turbocharger and a mechanically-driven compressor (supercharger). The timing mechanism uses a chain or a belt, depending on the timing system version.

Common malfunctions of TSI engines
| Malfunctions | Engines |
| The valve timing chain or belt stretches or breaks rather early. | CBZA; CBZB; BMY; CJSA; CCZB; CDAB; CHHA; BZB; CZCA; CJZB; CAVA |
| Excessive vibration of the engine at idling. | CBZA; CBZB; BMY |
| The engine is slow to warm up in cold conditions. | CBZB; CBZA; CMBA |
| The engine is highly sensitive to fuel quality. Carbon deposits build up on the intake valves when poor-quality fuel is used. | BMY; CAVA; CJZA; BZB; CJZB |
| The engine pistons burn through due to knocking. | BMY; CAVA |
| The piston rings stick rather early, which causes increased oil consumption. | BMY; CCZB; CZCA; CZDA; CDAB |
| Coolant leaks appear near the intercooler. | BMY |
| The turbocharger electronic control valve often breaks down. | CAVA |
| The engine pistons start knocking at a relatively low mileage. | CJZA |
| The ignition coils can break down due to malfunctions of the spark plugs or errors made during spark plug replacement. | CMBA; BZB; CCZB |
| The turbocharger actuator (wastegate) rod jams frequently. | CJZA; CMBA; CZCA; CZDA; CJZB |
| The engine is jerky at low RPMs. | DACA |
| The crankcase ventilation system gets clogged fast, which leads to increased oil consumption. | BZB |
| The high pressure fuel pump has a short lifespan. | CDAB; CCZB |
| The oil pump often breaks down, which leads to oil pressure reduction and can cause slipping of the crankshaft main bearings and connecting rod bearings. | CHHA |
