Just sold my f3 675 and they guy travelled about 150 kms with no issues, got on a ferry for 3 hours, then when he rode off the oil light came on and he had a constant beeping noise. He restarted and all was fine apparantly. Would this just be low oil ? I never had this issue when i owned and its typical it happened when i just sold it. Ive google it but no answers. Thanks.
