ATF stands for Automatic Transmission fluid and that is used in your power steering reservoir. Dex III. The engine running hot and reving is not a good thing. You don't want to overheat your BMW engine as you will contribute to warping the cylinder head. Check over your coolant system and make sure the system is properly bled.....

The tapping noise, I'm not sure. How many times did the car get "hot" of overheat? How is your oil? It might be the engine. Is it in the fan or belt area? If your handy with a wrench, peruse the forum I posted a link above and overhaul the coolant system if you have over 80K miles and it never was done before on the car. These cars need tender care to perform optimally. But if not them definitely have it looked at by a BMW mechanic before things get worse.

If the car is overheated, a lot of times it won't start. The ticking might have been the engine since the oil was thinning out due to the high temperature. Like I said, have the cooling system looked at before you drive any long distance.
