Spongy Audi A2 Brakes Need Professional Inspection

Had a similar issue with my Audi A3 2008 gasoline. The spongy brake pedal turned out to be more serious than just worn brake pads. The brake fluid had absorbed moisture over time, causing air bubbles in the hydraulic system. The symptoms matched exactly, inconsistent pedal feel and reduced braking performance. When checking the brake rotors and calipers, the mechanic found the brake fluid had degraded significantly. The solution required a complete brake fluid flush and bleeding of the brake lines to remove all air from the system. This is a safety-critical issue that needs proper attention. The squeaky brakes were just a symptom of the larger problem. After the repair, the brake pedal feel returned to normal with proper resistance and consistent performance. Most brake pad replacements should include checking the brake fluid condition, but sometimes this step gets overlooked. Suggest having both the hydraulic system and disc brakes thoroughly inspected, as degraded brake fluid can also accelerate wear on other brake components.

Thanks for sharing your experience. Going through almost the exact same situation with my A2 right now. The spongy brake pedal is really concerning. Got the brake pads replaced last month but still having issues with brake feel. How much did the complete brake fluid flush and system bleeding cost you? And has everything stayed working properly since the repair? Just want to know what to expect when I take it to the shop.

Just wanted to update, after getting the brake fluid flush and system bleeding done, everything has been working perfectly with my brake system. The disc brakes now respond smoothly, and that concerning spongy feeling is completely gone. The hydraulic brakes are performing exactly as they should. The total repair bill came to 240 Euro, which included fixing an undervoltage issue they discovered during diagnostics. The brake fluid replacement made a huge difference, the pedal now has that firm, consistent feel you expect when pressing the brakes. No more sponginess or irregular feedback. The brake shoes and rotors were also inspected during the service. Its been several months now and the braking system has stayed in perfect working order. Having properly functioning brakes really gives peace of mind, especially knowing the hydraulic system is completely free of air bubbles and contamination.

Thanks everyone for the helpful responses. Just got back from the repair shop and wanted to share my experience. The mechanic confirmed it was indeed a brake fluid issue causing the spongy pedal feel. They did a complete system flush and bleeding of the hydraulic brakes. The service cost 180 Euro which included new brake fluid and labor. During inspection, they also found slight wear on the brake rotors but nothing serious enough to need replacement yet. The difference is remarkable, the brake pedal is now firm and responsive. No more squeaky brakes or that unsettling spongy sensation when pressing down. Really glad I got this sorted before it developed into a bigger problem with the disc brakes. Will definitely keep up with regular brake fluid changes from now on. The mechanic recommended checking the fluid condition every 2 years to prevent similar issues. Thanks again for pointing me in the right direction!
