Hi,

I've tried removing the egr valve this afternoon, but am struggling on the the two Allen key bolts underneath ear the egr valve. I'm fairly sure the Allen key size to use us 6mm however it doesn't seem to loosen them.

Please can someone confirm the correct Allen key size to use, or offer advice on how to undo the bolts.

Thanks

Literally the second thing on this page.....
