Spongy brake pedal on Seat Tarraco

I am beyond frustrated right now. My 2023 Seat Tarraco with a diesel engine is giving me grief. It's done 124808 km, and the brake pedal feels all spongy and weird. I checked the brake fluid, and it's definitely low. I can't see any obvious leaks, so I'm pulling my hair out trying to figure out what's going on. Could it be the master cylinder failing? This is a disaster.

Low brake fluid is a common issue. When was the last time you checked your brake pads? Worn pads often cause the fluid level to drop. Also, is the brake system warning light on?

I haven't checked the pads recently to be honest. How would worn pads cause the brake fluid level to drop though? I thought it was a sealed system. And yes, the warning light is on now.

Right, the worn pads will lower the fluid. It's not 'dropping' as in leaking, but more like the fluid is filling the space left by the worn material. Seeing as the light is on, and you are not familiar with mechanics, get it checked out by a professional as soon as you can. It's not worth risking the brake system. It doesn't sound like a master cylinder issue, but I would check the pads.

I took the Tarraco to the shop, and you were spot on. The brake pads were completely shot. New pads and a fluid replacement later, and the brake pedal feels normal again. Cost me 480€ all in. Thanks for the help.
