Audi RS6 engine problems - instability and power loss
(Translated from Bulgarian)
Summary of the thread
A 2017 Audi RS6 with 170,000 km is experiencing engine misfires and power loss when warm, with the check engine light flashing and the TCE indicator lighting up. Initial suggestions include checking the fuel injectors, coolant temperature sensor, and crankshaft position sensor, as these components can cause misfires when faulty. The Mass Air Flow (MAF) sensor is also recommended for inspection and cleaning, as it can affect the air-fuel mixture and lead to similar issues.

Check the condition of the crankshaft position sensor. A failing sensor can cause intermittent misfires and uneven running, especially when the engine is warm. If the sensor is faulty, it may not provide accurate readings to the engine control unit, leading to the issues you're experiencing. Let me know if this helps or if you have any other questions!
