Seat Toledo Gearbox Issues

That sounds familiar. I had a similar issue with my Seat Leon, though it wasn't quite as advanced. Have you checked the gear oil level and condition? Sometimes just an oil change can make a difference, especially if the oil is old and degraded. What does the old oil look like?

Thanks for the quick reply. I did check the oil level, it was fine, but I didn't really pay attention to the condition. What should I be looking for specifically? Any telltale signs?

If the level is okay but the shifting is still rough, it's likely not just low oil. When I drained mine, there were metal particles in the oil, which indicated mechanical wear. If you see that, you're probably looking at a transfer case issue. It's best to get it checked out by a workshop.

The transfer case was indeed the problem, with significant mechanical wear. Repair cost 330€, but the car is driving smoothly again.
