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.
