Hi! I have just purchased a Citroen C5. 5 days later i got the message displayed "Diesel Additive Minimum Level" I have look in the owners handbook that says urgent top by your Citroen dealer. As anybody found a way round this, IE how do i fill it up? I understand you can buy the fluid but you may need the car pluging into a service computer to turn the warning off? HELP! :lol:
