My audi has been leaking oil im guessing its valve covers, but i am waiting to get money to fix it, my clutch is also going out. The main problem is my car would not start for a couple cranks like the battery was dead (i do play my music loud when the car is on and i do play it sometimes when the engine is not running but i try to keep it short) after the windows were not rolling down in one click i needed to hold it, after about 30 mins. the back windows would roll down with one click but it took another day for the fronts to work. The next day i noticed a big leak and it was coolant now it does not start (just makes a fast clicking noise like a machine gun), the back doors do not unlock with the remote and the horn sounds really weak when it locks also the lights do not flash with the remote. But the gauges and all the lights on the inside work. the gauge for the battery reads a little below half when i try to start it.
