CZEA 1.4 TSI ACT
The 150 PS 1.4 with cylinder deactivation, and the pick of the MQB petrols. It's smooth, genuinely quick and returns diesel-adjacent economy on a run, with the same water-pump habit as the rest of the family.

Engine and component issues
Rough cold idle, slow throttle response, misfires, gradual loss of low-end response. Direct injection puts no fuel over the intake valves, so crankcase vapour deposits bake on undisturbed.
Check: Not visible without a borescope. Treat it as a service item that's due unless there's a receipt. It's not a fault, it's an unbudgeted maintenance cost.
Coolant disappearing with no puddle underneath, a crusty residue around the front of the engine, and eventually a low-coolant warning. The water pump and thermostat housing on this engine family are a plastic assembly that weeps as it ages. It's a wear item rather than a defect, and because the pump is driven off the timing belt on the diesels the labour is more than the part suggests.
Check: Look for dried coolant staining around the front of the engine and check the expansion tank level against its marks. Ask whether it has been done, because most cars of this age have either had it or are due.
