Hi all,
I have a a6 tdi. My battery died the other day. Replaced battery but now car starts but then stops as if the immobiliser is cutting in. Also only three lights on dash the rest is dead. Any ideas?

Try leaving the ignition on in the key slot for a while and see if it resets.

You can also try disconnecting the battery leads and tying them together for 30 mins which works for some.

Thanks for the suggestions. Tried your suggestions previously at the weekend along with various others. Came home from work today, switched on ignition to run vag com again, and all is back to normal. The only error codes are obviously :

17978 - Engine Start Blocked by Immobilizer P1570 - 35-00 - -

but also

01561 - Left Rear Door 61-00 - Won't De-Safe 01562 - Right Rear Door 61-00 - Won't De-Safe

I'm wandering if these are linked, i.e short, voltage loss ,any ideas?
