Emergency services closed off the spur road while the blaze was dealt with.
Dramatic footage shows the vehicle which was turned into an inferno.
An explosion was then heard.
A National Highways spokesperson said yesterday (10 Mar): “The M4 southbound spur Heathrow in Greater London is closed between the M4 J4 and J4A due to a vehicle fire in the tunnel.
“Emergency services are in attendance.
“Please allow extra time for your journey. Thank you for your patience.”
Local Vik Singh said: “Mad.”
Matt Townsend added: “Such a massive design flaw having two of the terminals in the middle of the airport and only one road access.”

Holidaymakers and travellers were advised to get public transport or use the M25 J14 or M4 J3, as reported by Need to Know.
A National Highways spokesperson reported that the road has since reopened.
They said: “Traffic officers have advised that the M5 southbound spur Heathrow in Greater London between the J4 and J5A has now been reopened.
“There are several delays on the approach to Heathrow Airport so please allow extra time for your journey this morning.”
Heathrow Airport and London Fire Brigade have been contacted for comment.
