Exhaust leaking

Hi all. Noticed a exhaust fume smell if i let my vrs 170 FL tdi idle for a little while so i popped the bonnet open to have a look and it seems like the fumes are coming from were the exhaust joins onto the the turbo! Anybody ever had this problem with there vrs? Car has only done 30 k, just wondering if it's common occurrence on these! Bolts Might just need a nip up or need a gasket, just thought it was a bit unusual to leak from that part of the exhaust! Any advice appreciated
