Both front side lights are not working. All other lights are working fine.

new bulbs. No change.

measured voltage DC across both the light connectors and found 0v. (Very small voltage measured when the main headlights are on)

removed the negative battery terminal for 10 minutes. To reset the ECU No change.

bought a used frm module, swapped it out but they still don't work. I refitted the original

prior to swapping out the frm had fault codes read. The following were displayed

A125
A8C4
A8AC
A8AD
A8A9



I'm at a loss and dont want to pay £100/he to have this diagnosed and repaired. Any thoughts would be much appreciated

You might have to reset the short circuit counter using Tools 32.

The ballast could be toast.
