Hi all,i just recently bought my first audi ,and have to fix several problems in this car,such as belt noise (engine or power steering)valve gasket leak ,abs and brake lights on.But major problem is reverse gear ,when the car is cold it shifts with no problem but after driving awhile it just won't turn on,couple days ago when i was trying to
catch it by switching back and forth all the gears on dash became lit,but it turns in P D N sometimes R (i don't know about 234).Does anyone had such problem ,and what could be the cause of it(low fluid ,linkage,transmission computer or something else)?

By the way i got unlimited carfax for 1 month so if you need it let me know.

Thanks to all,sorry for the long post.
