and have been fixing this issue in the Q5, A4, and A5 2.0T engines by replacing the front crankshaft seal and crankcase ventilation valve. They have also updated the engine software to reduce blow-by pressure in the engine.
However, to get this done you must take the car back to the dealer, and remind them of the class action lawsuit in America, where Audi was forced to repair the issue. As a first step, the dealer must change the oil, and weigh the oil they replace it with. At this point, they must also replace the PCV valve, front crankshaft seal, and do the software upgrade.
You must then drive the car normally for 1600 km, after which the dealer will weigh the oil again to see how much you have used. If the problem persists, the only other way to fix the issue is to have the engine rebuilt to replace the pistons and rings with units that have been redesigned. This usually fixes the problem, but the real problem is getting the dealer to actually do a rebuild.
