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 

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.

Hi All

I own 2015 Audi and I had the same issue since yesterday.

I started the car after grocery and after that no matter i try start the car gives me all types of funny messages 

Brake service restricted, hill hold assist unavailable, low battery , alternator fault battery is not being charged, tyre pressure system fault , brakes fault safely stop vehicle .

 

Called the road assistance and they were able to jump start the car

When they ran the auto diagnose it is giving error errorcode:P1800 Generator

Have left the car to garage

will post the update once i hear from them

 

same happened to me after washing my car as hybrid battery had 0% charge.mine still reads no faults after visiting local garage. got my battery replacement booked at audi for tomorrow so ill let you know if that resolves it.

Funny how car works normally as long as the hybrid battery is topped up.

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?

i got the same error code this morning but my car seems to be driving fine. tried using OBD scanner but issue didnt show up. Please let me know what main dealer says if u do get it checked
