Good afternoon , I recently bought a used 2007 A6, little work to do ..
1- I have notice that the going home lights functions is not working. I have checked the functions and its On. Does anyone have an idea?

2- Where can i find a workshop manual online i found the little hose from the Intake filter (vacuum) connected to the engine but i don not where it does connect and it looks damaged so i need to order.

I am in Winder-mere Florida if anyone has a recommendation for me please let me know. Thank you
