I have gained extensive knowledge reading your posts and I love my audi and hope to do more work on it, hopefully someone here can help and end my quest.

1. buddy tried to test his car with my ecu

2. unknowing broke back cover for the plastic case housing ECU and relay.

3. Water leaked in, experience fan ralay issue as explained on this forum. Fan would blow all time and drain battery.

4. Cleaned relay and tried to fix plastic cover.

5. battery died and replace with cheap batter underpowered.

6. Alternator burned up due to batter.

7. purchase correct batter

8. fan relay died

9. car overheated and leaking so much coolant that had to fill every mile (fan still intermitend)

10. replace fan relay. and cover.

11. Fix leak behind engine due to deteriorated oring. Also on this forum.

12. Pull into shop after test drive on coolant and the car wont start or turn over.

13) key fob was not working. Fixed key fob. also found out the reason it wasn't beepiing was hood was up

14. Ran through start issues related to reprogrammging key. non issue


windows and radio work but car will not turn over. this happend to me before but the ECU reset itself in the process of fixing fan relay (all errors went away)


Left terminal off of negative took out relay. unplugged the side of the ECU that could be, turned on interior lights. no reset. no car start. I have left it off for the night maybe tomorrow morning.


HELPPPP I am fairly certain it is electrical but mechanic thinks it may be starter and he will test tomorrow for power going to starter. however because it happened before and fixed itself I am not confident of starter. because of recent cooling issues i read it could be bad coolant sensor?

Thanks you so much I want to get back to enjoying my car. A

 

sorry for any confusion
