Hi John, they did at first, then stopped. Took it to Audi, they changed the part but still the same. They said I need to change the 5f unit but wanted over £3k for it. Then on another forum, someone said check the pins on the connector as I can do the three button reset but nothing else. So I’m...

Hi guys, I am having the same issue with my a5. Audi replaced the the control panel but still have the issue. Going to look at the control head next. Did you manage to fix the issue?

Hi all, I recently posted on here about issues with the control module on my A5. I went to Audi, who replaced it, but didn’t fix the issue. After lots of searching on forums etc I have just noticed that the subsystem in question (part no 8T0919611K) is not being picked up by the vcds scan. It...

Little update - stop start has stopped working but he battery is only at 24-25ah which is really low, so I guess I’m needing a new battery. But after checking a few forums, I noticed on the 5F part of the full scan, there should be 4 subsystems but mine is only showing 3 and guess which one that...

Just an update. Checked the cable as suggested in the other link, it was broken and badly corroded. So fixed this and now I am getting battery readings in vcds plus the start stop is now working. Only thing is now I have got 3 error codes for the 5f unit : Address 5F: Information Electr. (J794)...

Just had a look in the area on the right, as in the link, and it looks terrible. A lot of water there, which looks as though it been there a while, bear in mind Audi said they checked all the cabling fuses etc, clearly didn’t check here. I have mopped up as much as I can but it’s started raining...

Well the guy at Audi mentioned the radio unit (called it the 5F module…..) but that is in the left side, plus I tried a second hand unit and it was the same. I will have a look at the second link you posted to see if I can see anything

Actually, I just read the second link you posted and I think that might be it one of the issues. I will have a look at that to see if it’s the same

Thanks for them, I will have a read through them shortly, as I have just been in the boot to check the battery etc and found a lot of water. In the pic, I had already mopped up quite a bit, but you can still see a little water (in red and my car is parked on a slant). From what I can see, the...

Just a bit of an update, I have not had a chance to try disconnecting the battery but I found a video on how to check the battery via vcds ( thanks to unlimited diy) and the results were not great. Based on the video, I should be seeing the voltage etc from the battery but it’s not returning...

No not tried that. I think the battery is the same one it came out of the factory with lol so I was assuming that those errors was due to that plus the stop/start doesn’t work, which from looking online, it could be because the battery is old and doesn’t have enough juice in it. But it is...

Hi all, I have read quite a number of posts regarding issues with the 5F module so I wanted to post my issue to see if anyone can help (apologies, it is a little long winded). everything was working fine on my 2012 A5 (facelift model), then the mmi control unit started randomly stopping...

Hi guys, sorry i know this is an old thread but I am having a similar issue which I think I need to change the baud rate but I am a bit of a newbie to all this so would really appreciate some guidance on how I change this. Thanks
