injector bolt size or tool required?

[stu76]

hi.

does anyone know what size or what tool is used to remove injectors for a citroen berlingo 1.6 hdi 2008 please?
looks like a allan key but tried my sizes and are either too small or too big!
presume prob a imperial or metric size required?
2 bolts that hold the injectors inplace. allan key shape with a star at bottom

if anyone knows please drop me a reply asap as much appreciated.

thankyou.

My reply is no help really, but I had a quick look at the Haynes manual but its no help as it just says "unscrew the injector retaining nuts...". I think you need a allan key to unscrew the nut but it sounds like its a non standard size. I believe the the star shaped bit you can see is the top of the stud and unscrewing that will unscrew the stud from the engine. I'm sure I've read somewhere that these studs are prone to snapping.
