Seat Toledo Diesel air suspension failure

Based on the error codes and symptoms, a faulty cable or plug connection is a plausible cause. Have you inspected the ride height sensors and wiring harnesses for any visible damage or corrosion?

Thanks for the reply. Where exactly are the ride height sensors located? And anything specific I should be looking for other than obvious breaks in the wires?

Confirmation of a defective cable or plug connection aligns with your vehicle's error codes and symptoms. The issues you are experiencing are indicative of malfunction with the suspension components. The diagnostic fee would be approximately 95€. It would be prudent to seek professional assessment at a workshop.

Thanks for confirming. Problem solved. It was a bad connection. 95€ later and it's working great. Appreciate the help.
