Disadvantages of the VW CFNB engine
- The most famous problem of the unit is knocking in the cylinder-piston group.
- The manufacturer changed the pistons under warranty, but over time the problem returned.
- The timing chain can already stretch to 100 – 150 thousand km, but it depends on the driving style.
- The exhaust manifold cracks quite often, and welding does not help for a long time.
- The left engine mount and throttle block also have a low resource.
