Hi, I replaced the battery on my Audi A3 TFSI Quattro, the other day. I obviously did not click and press the cover properly once I’d finished, and I have now dropped it whilst shopping and can’t find it so the battery compartment is exposed.Anyone know if I can just replace the cover(it’s the sliding part on the other side from where the lock /unlock buttons are) I’m afraid I don’t know what this part is called so it’s making it difficult to search for it. Any help or suggestions would be appreciated.. thanks.
