How Urgent Is the Overdrive (O/D Off) Light?
Urgency level for this indicator on the Cupra Terramar: low.

Frequently Asked Questions
Why is the Overdrive (O/D Off) Light on in my Cupra Terramar?
On a Cupra Terramar, the Overdrive (O/D Off) Light comes on because a monitored value crossed a threshold the car considers abnormal. It could be a simple, inexpensive cause or a genuine fault — the only way to be sure is to scan the vehicle and interpret the codes rather than guess from the symbol alone.
Can I keep driving with the Overdrive (O/D Off) Light on?
For a Cupra Terramar, a steady amber Overdrive (O/D Off) Light with normal driving generally allows a careful trip to a garage. A red or flashing light, or any change in performance, means you should stop and avoid further driving until the fault is identified.
How much does it cost to fix the Overdrive (O/D Off) Light on a Cupra Terramar?
There is no single price for the Overdrive (O/D Off) Light on a Cupra Terramar; it ranges from a no-cost adjustment to a component replacement. The honest way to control cost is to diagnose the exact code before authorising any repair, so you only pay to fix what is actually wrong.
