Annnd now the brake light is staying in and when info to drive it feels like the park brake is on but it isn't..do I need to do some kind of reset since the battery/car sat for so long🤦🏼♀️😩
I am surprised nobody has responded yet.
Jump start the car and drive it to a battery center for a battery test. It normally is for free. It could be a faulty battery, or the "new" battery has run down from standing and just needs a good charge until full.
If all else fails, read the manual. Is it the brake warning light in the instrument panel that is on, or the brake lights on the rear of the car? Not knowing a Touareg, what does the owner manual say about this light that is on? Several possibilities: It could be the light that shows your parking brake is on and has not been released. Or it could be a warning light indicating that the brake fluid is low and needs checking. Or, it could be a light indicating that your brake pads needs replacement. If no manual, drive to a dealership and ask for advice.
