Hi, I'm new here
I just did full service to my car (60k miles) and I've noticed a leak at the back of a gearbox. Maybe someone can help me to find out what happened. Gearbox oil changed at 40k miles at Audi Hull UK.
Do I have to take out whole gearbox or just the back part?
What could be the cost to fix it?
Do I have to change gearbox oil again?
Thanks
