Disadvantages of the VW AVB engine
The quality of the oil used has a major impact on this engine’s dependability.
Hydraulic lifters and camshaft cams deteriorate due to inadequate lubrication.
Leaks frequently occur when unit-injectors are not successfully fastened with a single bolt.
As a result, fuel may find its way into the lubrication system, posing a serious risk to the device.
Issues with the tandem pump and turbine are also frequently discussed on specialized forums.
