Seat Cordoba oil pressure issues

Low oil pressure on that engine usually points to a few suspects. Have you checked the oil level? Also, is the oil filter clogged? An oil change with the correct grade might help. Any signs of oil leakage?

The oil level is fine, and there's no visible oil leakage. I did an oil change recently, but the problem persists. How can I check if the oil filter is clogged or whether the oil pressure gauge is faulty?

Sounds like you've covered the basics. Given the noises and the warning light, a faulty oil pump is the most likely culprit. A clogged oil filter could contribute, but it wouldn't typically cause such a drastic pressure drop. The oil pressure gauge itself is less likely to fail. I'd recommend getting the oil pressure properly tested at a workshop to confirm, but be prepared for an oil pump replacement.

I appreciate the insight. I took it to a trusted mechanic, and you were spot on. The oil pump was indeed faulty. After replacement, including a new oil filter and oil change, the oil pressure is back to normal. Total damage: 755€. Thanks again for your help.
