Disadvantages of the Audi AVG engine
The turbine’s wedge geometry and pollution are the main causes of thrust failures.
Unstable engine operation could also be caused by a clogged EGR valve.
Examine the lower flange of the crankcase ventilation tube carefully if the sump is completely submerged in oil.
Here, a plastic cooling tube is typically the source of the antifreeze leak.
Loss of compression and valve seat burnout are frequent at high mileage.
