Hello everyone,

I'm sorry if you find some English mistakes because I don't speak English fluently.

For a little problem, I disconnected the battery to check all fuses.
All fuses are OK.
I reconnect the battery and when I turn key a big problem append:
When I turn the ignition, the dash does not light, no signal lamp.
If you try to start the car, it starts then cut (block) in the second after startup.

Many fittings do not work:
Ceiling lights does not work when the door opens.
The power windows do not work from another door that is located the command.
The remote has no effect on the car (open / close).

Hence the problem can come from?

See vagcom scan :

What Audi model is this, and what is the model year? Since you have the address 05-Acc/Start Auth. module I'm thinking a A6 or A8 of some type. The 05 module will shut all communication down if a problem is present.

Are you sure all of the fuses are reinstalled in the proper locations? What was wrong with the car that made you disconnect the battery and check fuses?

If you have a scan from before the car died please post the entire thing.

Thanks for your answer Dana.

My car: Audi A6 Avant C6 (year: 2006)

I will check this evening.

I start the bootloader from hidden menu MMI. Once launched, the bootloader runs continuously (even if the ignition off). When I made this mistake, I did not the CD update required by the bootloader. I had disconnected the battery while waiting for buying CD. When I reconnected the battery, (15hour later), all ECU on MOST(optical) bus “Cannot be reached”.
If MOST bus is down, bootloader cannot read CD in CD player (CD changer).
For this reason, I tried to see if a fuse did not have blown by reconnecting the battery

Yes, I perform scan before disconnected the battery:

You are right !!
Thank you for your knowledge.
There was a connecting problem in a fuse box.


However, my previous problem is still present.

can you help me to diagnose ?

Dana @ Ross-Tech

Post the Complete Auto-Scan from this vehicle. It would also be helpful if you included the results from the Optical test.

Hi,

That's the Gateway Installation list, not the Auto-Scan. Please see this video:

My interface is not in English -> I translated results of the auto scan.
I forgot to translate:
00384 - Bus de données optique
011 - Coupure
by

00384 - Optical Databus
011 - Open Circuit

to complete my post, here you are optical test result :
