Body in car likely toxic fume suicide
It has been reported that a passing dog walker raised the alarm and that notes had been placed on the vehicle warning of toxic fumes within the car.
Fire crews wore gas-tight protective suits to ventilate the car before removing the dead man, who is believed to be from Edinburgh.
The car was found at around 11am on Tuesday in a road leading to Cuddie Wood.
The road was closed for nearly two hours and the man's cause of death is still being investigated.
It is not yet known what chemical was used.
A Lothian and Borders Police spokesman said: "Lothian and Borders Police responded after the body of a man was found within a car. The death is currently being treated as unexplained and Lothian and Borders Fire and Rescue Service are currently assisting us.
"There are not thought to be any suspicious circumstances."
A report has been sent to the Procurator Fiscal.
