Hi all, just recently my AYC light started to come on after about 20 mins worth of driving, but goes off when i switch car off and back on.
Diff was serviced approx 4k ago

Can anyone help with this?

You need to get it code read, either by Mitsi using a MUT tool, or earthing out pin 1 on the OBD port and counting the flashes the lights makes.

This was happening with my 4 too,took it to Mitsi dealer and it gave code 82. Basically the AYC pump was worn out and not being able to presurise the system properly. But either way as grayw said you need to find out exactly whats wrong before you do anything.
