Hi,

I retrofitted a MIB2 High (8v1 035 035) unit into my PFL A3(factory fitted with MIB1 High, TSR, ACC with dome radar, Lane Assist,) , all works fine except some issue with Traffic Sign Recognition. Shortly after engine startup I get "Traffic Sign Recognition: Currently Restricted"-with the MIB1 unit I rarely seen that message-, but sign recognition appears to still work and I get posted speed limits or no overtaking signs on my instrument cluster. I also get this error on module A5, it reappears as soon as I clear it :

"Databus missing message: PSD_01_TO_FAILURE"

If I disable TSR from A5 coding, the error is gone. On module 5F: I tried disabling/enabling VZO, different settings for Car_Function_List_BAP_Gen2-traffic_sign_recognition_0x21_msg_bus, I tried to disable PSD from 5F coding byte24bit7, I tried PSD1.4/1.5 in 5F adaptations... but no luck getting rid of that error.

I noticed that the A5 controller has a coding byte for MIB1/MIB2, but my unit doesn't accept changing the coding to any of the MIB2 settings(I tried with Ignition On/Engine Off):


I noticed there's a 5Q0980653G H06 0060(mine's 5Q0980653E H05 0050) firmware available . Can I use this firmware on my module? Can this update affect ACC or any other front assist system? I know that I need to use VCP to parameterize the module afterwards. Calibration settings I assume I can just import my current calibration settings.

To get rid of that error, do I need to update the A5 firmware or is just some coding/adaptation issue?

Thank you!
