Technical Background
On Audi vehicles with 3.0L TFSI engine manufactured within a specific period, it is possible that the dynamic oil level warning function is faulty. This can cause the oil level warning lamp to light up even though there is sufficient oil in the engine.
Production Solution
New software in the Engine Control Unit (J623) addressed the condition.
