I have a 2011 Audi A3 with a gasoline engine and 205,000 km on the odometer. I am experiencing problems with the braking system. The brake pedal feels unresponsive, and when braking, I hear a sound as if air is escaping. The brake pedal must be pressed deeply. I have already had the brake booster and brake cylinder replaced twice due to moisture problems. Now, six months later, I am experiencing the same problem, but worse: there is now also a bubbling water sound when braking. Should I have the parts replaced again? I am at my wit's end. Does anyone have experience with this or suggestions for a solution?

Check the vacuum hose connected to the brake booster for any leaks or damage, as a leak could cause the unresponsive pedal and air sound. The bubbling water sound might indicate moisture in the system, so inspect for any signs of fluid leaks or contamination. If the issue persists, it's crucial to have a professional mechanic inspect it, as brake issues are safety-relevant. Let me know how it goes or if you have further questions!
