Re: berlingo help

A friendly Citroen dealer can tell you the age from the VIN, talk to the parts department, the info will be in their system.

With over 4000 vehicles listed you should find one similar to whatever it is you are trying to do. Many of the owners would be happy to discuss their vehicle details if you ask.
