Disadvantages of the Audi CJSB engine
The variable oil pump’s malfunctions are linked to the most severe issues;
The pump pressure-reducing valve sinks or the oil receiver mesh frequently becomes clogged;
The timing chain and phase regulators are not a very high resource in these units;
Every 50,000 kilometers, the boost pressure regulator V465 needs to be adjusted. Additionally, antifreeze leaks frequently happen here via the thermostat, pump, or valve N488.
