The 1.4-liter turbocharged Volkswagen BWK 1.4 TSI engine was assembled from 2007 to 2008 and was installed only on the basic modifications of the very popular Tiguan model. This power unit quickly gave way to a similar EURO 5 engine with the CAVA index.
The EA111-TSI series includes: CBZA, CBZB, BMY, BWK, CAVA, CAVD, CAXA, CDGA, CTHA.

Disadvantages of the VW BWK engine
- From bad gasoline, intake valves are overgrown with soot and then compression drops.
- Also, due to detonation, the pistons simply burn out and it is better to replace them with forged ones.
- Oil scraper rings often lie already by 100,000 km and lubricant consumption appears.
- The timing chain has a low resource, often it needs to be replaced by 100,000 km.
- The control valve and turbocharger wastegate also regularly fail.
- Owners constantly complain about antifreeze leaks, usually in the intercooler area.
- Another unpleasant feature is the periodic vibration during a cold start.
