Default PL: Problem with electrics

Hello everyone, I have a problem with my D3 4.2 MPI. It is about the very high current consumption at a standstill which is 6.5A. When I take off the fuse from the cluster instrument it drops to zero. I noticed that the meter wakes up the MMI system, draws 2.5A while the MMI draws 4A. After removing the fuse from the MMI the consumption drops to 2.5. I replaced the meter with another one but the problem is still the same. Does anyone have any ideas?

You need to scan the car with VCDS or similar. See what’s going on. Otherwise it’s just wild guesses over the internet.
