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.
