Soft Q3 Brake Pedal Signals Low Fluid Emergency Fix

I experienced similar brake system issues on my 2017 Audi Q5 diesel at 95000 km. The spongy brake pedal and low brake fluid level often indicate air in the hydraulic brakes or a potential leak in the brake lines. This requires immediate attention. When my brake pedal got soft, the inspection revealed air bubbles in the brake fluid and worn brake lines near the rear wheels. The entire brake system needed a thorough inspection, brake fluid flush, and replacement of compromised brake lines. The fix involved: Complete brake fluid flush, Brake line replacement, Bleeding the brake system, Full inspection of brake components, Testing brake pressure This was a serious safety issue since compromised brake lines can lead to complete brake failure. The repair took about 6 hours at the shop. The symptoms you describe match what I experienced before the repair, and waiting would have made the problem worse. A certified brake specialist should inspect the car soon. They will check for: Leaks in the brake lines, Master cylinder condition, Air in the brake system, Brake fluid contamination, Overall brake component wear

Thanks for sharing your experience. My brake pedal issue got resolved after a complete brake fluid replacement and system inspection. The mechanic found minor leaks in the master cylinder that were causing air to enter the brake system. Did the repair cost align with what you paid? The total came to 460 Euro for my fix including parts and labor. Just wondering if thats in line with what others experienced. Also, has your brake system remained solid since the repair? No recurring issues with pedal feel or fluid levels?

After fixing my brake system issue, I paid 480 Euro for the complete repair, so your 460 Euro charge sounds about right for addressing brake system problems. The price typically covers the brake inspection, parts, and labor needed to restore proper brake function. Since having the work done, my brake pedal has maintained firm pressure and the brake fluid level has stayed consistent. The initial diagnosis revealed worn brakes and low brake fluid, but once fixed, I have not experienced any recurring issues. Regular brake inspections show everything is working as it should. A properly repaired master cylinder and brake system should give you reliable service for many kilometers. Just keep an eye on your brake fluid level during routine maintenance checks to catch any potential issues early.

The brake repair went smoother than expected. After reading replies here, I took my Q3 to a certified brake specialist who quickly spotted the master cylinder issue. The warning light had started flashing on my dash during the drive there, which confirmed my concerns about waiting any longer. The repair took about 4 hours. They flushed the hydraulic brakes, replaced the master cylinder seals, and checked all brake lines for potential leaks. Total cost was 460 Euro, which seems fair based on other responses. Three weeks later, the brake pedal feels firm again and no more warning lights. The brake fluid level has remained steady during my checks. Really glad I addressed this promptly rather than continuing with my previous mechanic who kept dismissing the spongy pedal feel.
