News ; Reviews ; new cars ; These wastegates are regulated by an actuator. In this case with the 1.4 TSI/TFSI, the actuator is prone to sticking or developing rattling noises. When it rattles, it delivers a poor boost, which can damage the performance. But when it is stuck, it can deliver excessive boost which can damage the turbo. But the more time that passes the more I get interested in making it move a bit faster but still be reliable. Golf 7 1.4 tsi GT Feb 11, 2021 #5 EA211 1.5 TSI Engine Problems and Reliability. The 1.5 TSI is defiantly more reliable compared to the 1.4 TSI EA111 engine. Most of common 1.4 TSI problems were eliminates in the next 1.4 TSI engine of the EA211 family. Now, the 1.5 TSI is based on huge experience in the engineering and production of small turbocharged gasoline engines. chopchop said: If you want a car to last 200,000 km without any problems, buy a car which is less sophisticated than a 1.4 TSI Volkswagen.

These engines have reliable performance, power, and fuel economy. From the days of the iconic love bug to the The most of the tuned 1.4 tsi have stock pistons without problem, pistons are durable till 270hp BUT 1.4 TSI 180hp version( Polo GTI, Ibiza Cupra,etc) have problems with high oil usage . Also the first 1.4 TSI CAVD(Scirocco) at 2008-09 production had problems with broken pistons this is why the 24S4 Update was a MUST from VW .
