Hello, I have a permanent error code on my 2009 bva freel when I bank AP2000 but I don’t know where to start. The code is P061b-81.
I can’t find anything in the research.
If I continue on AP2000 he offers me the reset of the bva. However he specifies that it is to do for a new bva
Can you help me please ?

I get this from time to time...more likely due to a low battery or a earth problem. These fl2's are complicated electronically and like a fresh charged battery..

clear it and if it goes away don't worry about it. Mine pops back occasionally but has never been an issue in the 14yrs ive owned the car

What is a BVA ?

My list of FL2 DTC code says

P061B Internal control module torque calculation performance

sub code
81 - Bus signal/message failure - invalid serial data received Jules

Boîte de vitesse automatique (BVA) = automatic  2007 TD4 HSE

Thanks for your help. I’ll try to erase the code tomorrow and hope it doesn’t reappear

Here are the screenshots of the frozen default values,
