nc11 Posted November 1, 2022 Share Posted November 1, 2022 Have had a 2014 e-tron for the past year with no issues at all. Service was done 2 months ago at 95k miles. I've just had this error appear on the dash - electrical system fault. contact workshop. It comes up when you start the car and disappears when off. Car drives well, so brought it to the garage I use for service. They plugged in the computer, and the test stopped on B201A00 : Checking software version management. Unfortunately it looks like I'll have to book into a main dealer Before they charge me the earth, has anyone seen this error message? 1 Quote Link to comment Share on other sites More sharing options...
Steve Q Posted November 5, 2022 Share Posted November 5, 2022 It might just need a software update. But you'll still have to Psy for the diagnosis fee unfortunately. Quote Link to comment Share on other sites More sharing options...
Simon Alderson Posted March 20, 2023 Share Posted March 20, 2023 Interested to know if you got this issue resolved? Mine has just done the same thing, two weeks after I got a whole host of electrical faults and the car shut down in the middle of the road. I had the battery replaced then as it was knackered, which seems to have fixed it until now. Audi have told me its safe to drive, but again main dealer recommendation, and it’s literally months until it can be seen! Quote Link to comment Share on other sites More sharing options...
orang Posted November 14, 2023 Share Posted November 14, 2023 I have a 2015 e-tron, I had no problem until now, but I got the same fault 2 days ago. I went to the workshop and they told me, they can not communicate with ECU to check the issue. Anyone had a similar problem? Quote Link to comment Share on other sites More sharing options...

Jbish Posted March 19 Share Posted March 19 Hi, when you talk about battery replacement. I’m assuming this is the standard car battery, rather than the hybrid drive battery? im getting the same error today. 2015 A3 etron any. Info gratefully received Quote Link to comment Share on other sites More sharing options...

Info gratefully received Hi, yes i replaced the 12V battery and the fault code disappeared. the dealer told me it was because I have not been charging the car often enough and especially during winter the 12V battery was really struggling to stay alive haha. Hope this helps sorry for late reply. Quote Link to comment Share on other sites More sharing options...
