Audi Stereo creating ._ versions of file on SD card

Followers

January 21, 201610 yr

I'm new to using the SD card with the audi stereo, but following the instructions I've found on the web and various Audi docs - I'm working. Not as I would like but a good starting point.

I'm just testing at the moment so I've copied across a folder with 1 artist with multiple albums in sub folders under it. This seems to work well and the Audi stereo can navigate this fine.

However, when I enter an album folder in the stereo navigation screen it seems to scan the folder for tracks, and then creates a ._ version of the file as well as the original.

for example, if I take the card out of the car and put it back into my laptop the folder looks like this

-rwxrwxrwx 1 mattd staff 4096 21 Jan 14:31 ._01 Who Did You Think I Was.mp3

these ._ files where not on the card when I put it in. The in stereo navigation system also shows these files and can't play them.

why is it creating them ? what are their purpose, am I approaching using the SD card totally wrong.

January 25, 201610 yr

Do these new created files actually play on the laptop or not at all?

January 25, 201610 yr

no,

I think I figured what was going on with this and it was a small bug in how my mac was setup.

all sorted now.

Are S5's notorious for not being serviced?

ZeroX · Saturday at 10:46 AM4 days

Hi, following on from my previous thread, I have seen another car that I was interested in: https://www.evanshalshaw.com/search/details/used/audi/a5/automatic-petrol-white-coupe/06ce9494-f94d-f111-8fdd-000d3a874790/ When I enquired with the dealer, they said there is only one stamp in the book from February of this year, and no history at all in the Audi database. So there is only evidence of 1 service in almost 10 years. I am starting to get a bit !Removed! off with this actually, and it's real

Bose radio antenna mouse damage!

Robert Coop · yesterday at 08:53 AM1 day

Good to join the Forum. A mouse got into my wife's beloved light blue 2004 A4 TDI Sport Auto Convertible (she has had it from new) and has chewed through the aerial cable under the back seat. and damaged it in two other sections. What connectors are recommended to re-join it and are they easily sourced - the garage made out I might need to go back to the loom - surely not? The radio is the original Bose Symphony. Thanks, Robert

I've been seeing more and more posts across FB and multiple forums about people having the alternator failure related to the 48v mild hybrid system and wanted to see if anyone has had this issue and how their experience has been. I know in USA they have announced a TSB with an extended warranty for 7 years but I am trying to get more info from Audi UK but not getting anywhere. Has anyone had this issue and if so has Audi fixed it (if out of warranty)? It seems to be tha

Hello everyone, Wondering if anyone can help me. A few weeks ago my EPC light came on and immediately went into limp mode and started jumping when driving at 5mph. After a few hours I came back to the car and it was fine so I drove it to my storage unit. I came back the next day and when starting it the EPC light and EML light were illuminated and the idle was quite rough. I came back to it about a week ago and all the doors were locked, the key isn't unlocking it and the barrel of the central

Hello all, I’m a 21 year old man who has a a4 b9 and I’m currently paying around 400 pound for the car, I absolutely adore the car but the monthly payments are absolutely overwhelming me, selling it would be a last resort. So I ask, does anyone have any advice I could use to lower my insurance on it, any ideas will be much appreciated.

TomMelluish · May 8, 20251 yr

Hi everyone, I've got a lovely old Audi 100 Quattro 2.8E from 1994. Sadly the bearings have gone in the interior blower, leading to horrible noises any time I try to use the climate control. I tried to source a replacement part, but the one that was sent has a different mounting to what's in my car. I can see one number on the old blower, but web searches don't seem to find anything for it: 3135102138 I ordered one of these from autodoc.co.uk: 2669I0008 RIDEX Interior Blower
