Popping sounds over bumps, root cause unidentified.

I have been noticing some popping sounds coming from the passenger side whenever i go over bumpy roads and its driving me crazy. Went to M Performance to diagnose the problm and the guy said it was the nut under the front bonnet coming in contact with the bonnet. Long story short, the mech tightened it and said it was ok. But after driving off fr a couple kilometers the sound came back. Before i go for a second round at the workshop, perhaps some members here have faced a simillar problem and came about the solution?Im driving an e90,320i, if thats any help. Thanks fr the help guys.

nuts holding down the anti roll bar were loose. Good ol torque wrench on em did wonders.
