Hi all, yesterday I removed the Egr valve on my 307 07 plate 1.6 HDI. Gave it a good clean out and put everything back together but when I went to re start it it tried to turn over a couple times then just stopped like I had stopped turning the key. It's now just clicking like the battery is flat but I've checked battery and all is fine? Got my brother over to help and the engine has seized? Any help as to what the hells gone wrong? Am hoping for diagnostics later today but I'm completely lost any help????? Please!!!
