Cookle Posted April 16 Share Posted April 16 Hello, First time poster here, I’ve had my Audi A3 V8 for two years now (66plate) it’s been perfect but the last week a few faults have occurred and my EPC light is on on the dash board. First fault code - B105313 - GSM Antenna Open circuit. i have no idea what this is or means, could anyone give any advice? Second fault code - U11B800 - Interface for external media - no communication. if I am thinking right this means the USB ports in the car, I have no idea why this has just suddenly stopped working as I have never used them, I don’t even use the media, I just listen to the radio so this has stumped me. My check engine light has come on as well (Yellow version) I understand this was down to having low oil in the car but I got it serviced this morning and I am still having the issue, I have no power when driving and the revs are taking ages to catch up. The fault reader isn’t showing any codes for this which I am confused about. Has anybody had these issue before that could lead me in the right direction, Thank you for your help.

Brad Hi I am thinking water has ingress under the antenna on the roof as for the fault codes for the rest of the car most of these are better read by VCDS, obd eleven or similar, Steve Quote Link to comment Share on other sites More sharing options...

Hi sorry to hear of your woes, I would definitely look at OBD eleven it will give you better scope to at least identify your problems and as code readers go its cheap. Steve.
