TSI engines: what it stands for and its performance parameters

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

MalfunctionsEngines
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
