Trunk problems
New here but I'm owner of my 2011 Audi A7 2.8FSI since new.
So the boot wont lift up. The long story goes like that:
3 months ago there was a problem with water pump. I drove a bit too much as it was showing alternator problems.. They fixed the problem but shortly after I had to rebuild the whole engine.
A few days before that I got lot's of errors, low battery, start/ stop system was not working, wing went out and it was not possible to put it manually. So I replaced the accumulator/ battery for a new one. Got rid of all errors but from that point the trunk wont open. The trunk was working fine before I replaced the accumulator as I opened the trunk with my key.
The accumulator was written in the system too.
Basically the trunk detach when you press the button on the trunk but won't go up. You have to push it with hands. Also to close it you have to push it manually but at the very end it closes smoothly automatically.
I plugged the computer on the car but it is not showing any errors.
Is it possible that the acu is not full enough? Or there is something else?
Thank you guys for your help
