How can I check and refill the brake fluid in my Audi A3?

I've noticed my brake pedal feels a bit spongy and I want to check and refill the brake fluid in my Audi A3. What steps do I need to take and what type of brake fluid should I use?

To check and refill the brake fluid in your Audi A3, locate the brake fluid reservoir which is usually near the back of the engine bay. Open it and check the fluid level, making sure it is between the MIN and MAX markings. You can then top it up with the correct type of brake fluid, which should be listed in your owner's manual. It's important not to mix different types of brake fluid as this can lead to performance issues.

When checking and refilling brake fluid in your Audi A3, make sure your car is parked on level ground and the engine is cool. You may also want to use a funnel to avoid any spillage. It's also a good idea to wear gloves and avoid getting any brake fluid on your skin as it can be corrosive.
