Knocking/clunking noise

[smithyc1987]

Hi all any help aporeciated ive got a 2008 gti lowered.
It has developed a clunking noise when going over uneven surfaces quite slow,
Sounds like its the rear of the engine under center console middle sort of area
Only hear it over bumps in road when going slow 30mph max.

Could this be subframe bolts etc or something else
Thanks chris.
