Hi everyone with 1500 RPM all loads switched off my alternator output is 13.3V seems low can someone else please measure their output?
Thanks.

Where are you measuring?

Seems a bit low to be honest.
How are you measuring it?
Multimeters can vary unfortunately.
When measuring mine now I use an OBD2 dongle and the torque app on the phone.
This gives the voltage that the ecu is seeing.
On the RS4 B7, I'm seeing about 13.9/14v with engine running and no ancillaries on.
