When I drive my RS2 and change gear, during the release of throttle (gear in neutral) the engine rev drops around 500RPM and almost. It only happens whenever the car is warm up. Battery is just replaced but problem remains the same.
I notice when this happens the voltmeter indicate the voltage has dropped a bit to less than 13V. Without this problem the voltage is usually slightly above 13V
Could my problem be related to the alternator? If yes is 034903016NX the correct part no? can I use this no. instead 034903016 or any other cheaper approach to fix this issue?
Here are the photos of what the voltmeter shows:
