Touareg Brake Pedal Spongy with Low Fluid Level

Having experienced similar symptoms with a 2011 VW Tiguan 2.0TSI, this definitely requires immediate attention. The spongy brake pedal combined with low brake fluid strongly suggests either a leak in the hydraulic brake system or air in the brake lines. Last month, the brake warning light came on in my Tiguan. Inspection revealed deteriorated brake lines near the rear calipers, allowing air to enter the system. The brake fluid was slowly leaking, creating that exact spongy pedal feel described. This kind of brake issue is serious and potentially dangerous. When air gets into hydraulic brakes, it compromises the entire braking system. The hard resistance felt when pressing the pedal typically indicates air bubbles in the lines. Required repairs included: Complete brake fluid replacement, Brake line replacement, System bleeding to remove air, Inspection of master cylinder and calipers The symptoms match classic brake line failure or significant air in the system. Driving with these conditions risks complete brake failure. This needs professional attention within 24 hours, ideally from a certified VW specialist who can properly diagnose and repair the hydraulic brake system.

Thanks for sharing your experience with the Tiguan brake issues. My Touareg showed nearly identical symptoms last year. The master cylinder ended up being the culprit, letting air into the brake system. Quick question, do you remember roughly what the total repair cost was for your brake line replacement and system bleeding? Also curious if any other brake issues popped up since getting it fixed. My repair was pretty costly but wondering how it compares to yours. The brake pedal on mine is still perfect after the fix, but I make sure to check brake fluid levels monthly now after that scare. Better safe than sorry with brakes.

Glad to provide an update on my Tiguan brake repairs. The total came to 480€ for new brake lines, complete brake fluid replacement, and system bleeding. The worn brakes needed attention, but the hydraulic brake system has worked flawlessly since the fix 6 months ago. The brake fluid level low warning hasnt returned since seeing the mechanic. Keeping an eye on fluid levels is smart preventive maintenance. Regular checks can catch issues before they become major safety concerns. Like you, I now monitor the brake system more closely. No warning lights or pedal issues have occurred since the repair. The pedal feel remains firm and consistent, exactly how it should be. A properly functioning brake system is worth every cent spent on maintenance. The peace of mind from knowing the hydraulic brakes are working correctly makes the repair cost worthwhile.

Thanks for the helpful advice. After reading about similar experiences, I took my Touareg to a new certified shop. The inspection revealed air in the brake lines and a failing master cylinder, just as suspected. The repairs came to 620€ total: New master cylinder, Complete brake fluid flush, System bleeding, Full brake inspection The mechanic explained everything clearly and showed me the worn parts. The brake pedal now feels solid again, no more sponginess or weird resistance. Money well spent for safety. Been checking the brake fluid level weekly since the repair. Everything has stayed perfect for the past 3 months. Really glad I didn't wait any longer to get it fixed. Will definitely keep up with regular brake maintenance from now on. Thanks again for helping identify this as a serious issue needing immediate attention. Could have been dangerous to keep driving it in that condition.
