It sounds like you have a bad sensor, indicating the brake is engaged when it's not. Have you noticed if it tends to display the error when you go over bumps or turn sharply?

SOURCE: oil pressure warning light on my audi a4 2005

The car has entered into fail safe mode. It wil not allow the engine to rev high but allows you only to get to a mechanic or to get some oil into the engine. What's the level like? Is there any trace of leakeage?

SOURCE: Left rear brake light stopped working but bulb and fuses are OK.

take the bulb back out have someone sit in car apply brake get your self a circuit tester and check to see if this circuit is carrying efficient 12 volt current! some times in cold weather these bulbs get hot with long period of breaking and when released condensate and rust begins and you get what you have perhaps bad socket! this would be a ideal location to begin and probably end,

SOURCE: beeping sound and flashing brake light

That is a sign that your ABS controller is failing - www.modulemaster.com can rebuild it and warranty it for you.

Do the ABS brakes function? If not, there is a fault with a wheel sensor or the ABS controller. Check the OBD Codes. You can get them scanned at Auto Zone for free. If there is no communication from the ABS control unit, that's probably bad and needs to get rebuilt. Cost about $150.00 if you send in your unit.
Good Luck

SOURCE: Audi A4 need to replace rear brake light on audi a4

Inside the boot is a plastic cap embeded in the boot liner. Remove the cap to reveal a screw. Undo the screw and the whole rear light cluster will come away in a sideways and not rearward direction to reveal all of the bulbs. Hope this helps.

2 questions about my 2004 Audi A4 1) Why would the red "Brake" light in the dash randomly blink & beep as a warning? 2) How much to replace the Wiper Blades?

The brake lite could blink when the brake fluid goes too low, before you add fluid check to see what type you need could be dot 3 or dot 4. there might be two types of wiper blades cost between 30 and 90 dollars.

Mk1 A4 ABS warning light

I have a 2000 Audi A4 and the break wear sensor warning light come on for me too. It does not flash and is orange in color. I have asked the Audi dealer twice about it and they told me it's because the previous owner put aftermarket break pads on it, thus messing up the sensors. I don't know about the ABS warning and other than that I wish you luck on it.
