Shortly after getting my S5 I saw some DTCs in a scan which cleared and could have been due to the work I had been doing with VCDS so didn't think much about them. They haven't re-appeared for many scans but did again yesterday. They are:
19 CAN gateway
00384 - Optical Databus
011 - Open Circuit - Intermittent
5F Information Electr.
02067 - Optical Databus; Unpermitted Wake-Up Request
000 - - - Intermittent
These seem to be fairly common and possibly related to retrofits, but that's not my case - my car is 15 weeks old from new. Obviously its under warranty so I'll get it checked out at a dealer sometime but there are no obvious symptoms - everything seems to be working fine - so I'm not in a hurry, I'll wait for the next service.
Nevertheless I'm interested to see if I can find out any more about this hence this post to see if anyone else has had such issues.
I did the VCDS optical bus diagnostic and it returned 'OK' for 19 (CAN gateway), 47 (sound system) and 56 (radio). This surprised me because I'm sure there should be other equipment on the bus. I decided to try again with the 3dB attenuation option but it failed, with 'ERROR' for 56. I then had other DTCs:
19 CAN gateway
00384 - Optical Databus
011 - Open Circuit - Intermittent
47 sound system
03278 - Functionality Limited due to Missing Messages
000 - - - Intermittent
56 radio
03278 - Functionality Limited due to Missing Messages
000 - - - Intermittent
5F Information Electr.
03157 - Functionality limited due to Communications Disruption
000 - - - Intermittent
03278 - Functionality Limited due to Missing Messages
000 - - - Intermittent
Again these all cleared and I did a final autoscan which had no errors.
I assume that I must have a bad optic connection somewhere. Can anyone share any similar experiences?
