Amber — check soon
Transmission
The transmission unit has stored a fault. Often the car locks a single gear at the same time — that is limp mode, a protection against damage rather than the damage itself.
An amber lamp means you can drive on, but do not put it off. The car runs in a protective mode and usually drinks more.
What to do now
- Stop and switch the engine off for a minute. A one-off glitch clears on a restart, and that is the first thing to try.
- Check the transmission fluid level if your car allows it: a low level produces pressure faults before anything actually breaks.
- Do not push the gearbox: if it is holding one gear, drive gently and not far. Kickdown and hard acceleration in this mode lead straight to an expensive repair.
- Read the code: gearbox faults are not readable with every adapter or on every car, but where they are, they name the assembly at once.
Codes usually behind it
The lamp only says that something is wrong. The code says what exactly — read it with an adapter and look it up here.

What to read next
A lamp is not a diagnosis. The same symbol lights up for a dozen different reasons, and only the code stored in the car tells them apart.

The same fault shows itself in different ways. Each sign below says what to look at in the live data.
How the app helps
CarScan reads the codes behind the lamp through an OBD-II adapter, explains them in plain words and puts them into a report you can show to a mechanic.
