Cooling
Some 1.4 TSI engines have reported ignition coil faults or breakage; replacement may sometimes be needed even during spark plug maintenance.
Engine Bay
The 1.4 TSI engine uses direct injection, which can lead to carbon buildup on intake valves over time, causing rough running, power loss, and check engine light or misfires.
Engine Internal
Some 1.4 TSI variants (EA211 and its evolutions) have reported issues with the wastegate actuator (rod stuck or broken) and other turbo mechanical parts; this can cause boost loss, poor turbo response, and check engine light.
