Disadvantages of the VW ABU engine
The owner’s primary issues stem from malfunctions in the mono-injection system’s operation.
Examine the throttle position potentiometer at floating engine speeds.
Failures in the ignition system, which is not very dependable, come in second.
The coolant temperature sensor frequently malfunctions electrically.
The remaining malfunctions are typically related to attachments or wiring.
