RPM meter does not go to zero

Hello,

I have a weird problem. I have recently changed the second (big) battery, and shortly after noticed that after turning the engine off, the RPM Meter does not go to zero and stays on 2k.

​​​​​​When I start the engine, it goes up +1k, the engine works stable.

The feeling that it confuses the initial 0 with 2000 and goes up from there on.

Any ideas what can cause this behavior?

I guess this could be a part of the battery programming, i.e. one should explicitly let the system know that the car got a new battery (via VCDS).
I did not expect it to impact the RPM meter thought.

After few days got back to norm itself 🙂
Also, turns out Bentley does not need any explicit battery programming after replacement.
