The high-pressure fuel pump cam follower on B7 2.0 TFSI engines wears through due to inadequate hardening, destroying the camshaft lobe beneath it.
dangerous
Multitronic CVT gearbox failure (B7)
The Multitronic CVT transmission is notoriously unreliable with widespread failures affecting the steel belt, pulleys, and control systems.
dangerous
Oil pump chain failure (B8)
