Skoda Kodiaq Diesel Radiator Oil Pressure Error

Transmission indicator and check engine light on at the same time? Sounds like a bad day. Slipping and grinding? Have you checked the oil level? Is the car overheating or losing coolant? Could be as simple as low fluid, or maybe there is a leak. Is the cooling fan working?

Oil level is fine, no signs of leaks, and the cooling fan is spinning. Car overheating is not happening. You mentioned 'simple as low fluid' - would that cause the 'Radiator oil pressure defective' error? Seems like a weird connection.

If the levels are ok and no car overheating is happening it's likely an electrical issue like the error code says. A low-fluid situation causing that specific error is like saying a flat tire caused your radio to stop working, it does not add up. If the error code is pointing to a wiring issue I'd take it to a workshop and have them check it out before you do some serious damage.

It was a faulty cable/plug connection to the oil cooler. No radiator repair was needed. Cost me 95€ to sort. Thanks for the input!
