Disadvantages of the VW CAVA engine
Detonation is linked to many engine issues because of the fuel’s quality.
Pistons are simply cracked by bad gasoline, and many people replace them with forged ones.
Here, the intake valves rapidly become overgrown with soot, and the cylinders’ compression decreases.
Although the timing chain has undergone numerous modifications, it hardly ever travels more than 100,000 kilometers.
The electronic control valve and wastegate of the turbine frequently malfunction.
The intercooler area is typically where the coolant leak originates.
