just got my new syncro ambulance high top , 5 pot audi and both diff locks however today the front diff light just started flashing ???? didnt use it just started pulsing ???? is it f@@@ed and how do i fix it ??????? ????
Push it back in, it flashes when you have pulled the knob out before it engages, to warn you that you have requested engagement. Engagement can take a little time for the cogs to align, unless you are stuck and wheel spinning when it should engage straight away.
The light should go solid green when engaged.
The warning flash is because front diff lock prevents proper steering.
