DOHC

First off, i'm new here, just got an IS250 two weeks ago. It replaced my much loved Audi TT, but i'm looking forward to enjoying the IS. Few days back I took a curd to close and my tire kissed the curb for a few secs....during the process I heard a loud high pitched beeping noise coming from inside the car....since then I have not had any problems or any warning lights come on in the car. I spoke to my dealers service department and they said it could be the following:

1. Brake booster is out?
2. ABS is shot?
3. Tire preassure system letting me know air is coming out of the tire?

Which number do you think? I have an appointment with them to inspect the car for anything that may be a problem.....but i'm unsure if it is as big as I think it is? Thanks for help on this.

1. if your brakes work fine then your booster is fine. You'd notice a loss of braking assist.
2. If ABS was not working you would have a light on your dash showing all the time.
3. The tire pressure monitering system let you know if there is low pressure in a tire. It doesn't tell you which one though.

I am un sure what the beeping noise you heard was. It could have been the OH ****! alarm....

It may be the "What the hell is going on" alarm....but I may just take it the dealer and have them but it up on a rack. I guess it may also have been the VSC control as well.....
