Hi All

Appreciate any comments. My c3 has worked with minimal problems over last 10 years but it is coming to an age now that I am getting all sorts of problems.

I had gearbox fault flashed twice this month on the display. It usually happened when I slowed down and the gear start to change. When the error message appears I lose all acceleration for about 2-3 seconds until it starts again.

What do you think is the issue?

Thanks
Amit

This means there are fault codes stored in the ECU.

You need to have these codes read for the description of the fault.

Use a lexia tool on a laptop to read the codes. Info about lexia here (because it is a bit complicated).

You probably have a clutch/actuator fault but without reading the codes, you won't know :)
