Great advice. Have already been on the Citroen service website and it looks like a under engine protector should be fitted. Will provide more feedback after visit to dealer. Thanks. Phoned several dealers who all looked up on their PCs and said my car didn't come with it factory fitted. Yet I would swear I can see the circular mark where a stud of some kind used to be on the side rail where an undertray would be fitted. Plus if I put my VIN into the Citroen service website it comes up with 2 options (one 2010, one 2013). But the dealers tell me that if the part nos are blacked out on their screens it means your car dosn't have it. Not going to pursue this any longer, I will assume the dealers are right (!?)
