Need help wont start

[snakelimit]

Hi all
thats my first post here but i did was using forum from ages, now time come where i dont know what to do.

All start few months ego when i did go to automatic carwash for first time with a6 as normal I did with my passat drive in put on neutral and let the car been drag and wash when reached end of it i did select D and nothing happen then i did notice engine was switch off and did not want to start, lucky for me carwash guy helped me and we did try jump start as battery did go down, aftre few times engine started and i did drive away was driving about 25 min to charge battery and then go to my garage but was arledy closed, then went tesco and go do shoping when did come back car did not start again, this time i did call my frend with obi scaner and see if he can help me and there was a error. We try jump start again but nothing happen then he decided to disconnect battery for 10 minutes and after that car was back to normal, start and drive normal, i did reserch error on forum and find it was throttle body or intake manifold motor v157, i did buy one from ebay and replaced after that all was back to normal ah and i did have engine managment light on but was cleared with vcds.

Few monts after that i did not drive about a day or 2 when go to the car he refuse start again i did check all what on forum other ppl was poiting did remove pipe and see if flap is in closed position or if is open when scaned by vcds show same problem after few times battery did go down then i did recharged and manage start engine after that all went back to normal started in first time up to last sunday when i did not drive for about 1,5 day and again did not want to start i scan for errors and again same v157 error i did check what i could and will post 2 videos what happening when i try start and throttle body. Now battery is down and need recharge again i did removed throttle body egr and airintake mainfold and give probly cleaning removed carbon replace gaskets put together, clean codes and still wont start i did same trick with disconect battery for 10 min to reset all but that did not help this time around, today I did try jump start and nothing happen im not sure if that is v157 or is just battery or somthing else, when i did charged it show 100% and then go dwon to 10% after few trying and scans.
My frend will try borrow battery to see if that is a problem before i spedn cash on it. Please see this 2 videos and tell me what u think i will post vcds errors layter as i dont have on my ipad.
regards and tahnk you for any help
