I have a 2013 Evoque Coupe purchased this summer. Since new I had an intermittent 'thunk' noise during bumps coming from the rear. Very annoying as otherwise this is a noise free car. Finally over my holiday break from work I had the time today to investigate. My guess from the resonance that it was exhaust, suspension, tailgate panel or else a bad strut and I assumed it would be hard to locate. Within several minutes I found the source. The rear metal seatbelt clips on the seatbelt straps that hang down close to the rear plastic side panels would strike the panels during bumps producing the noise. Happy to solve the problem (leave them fastened) but I'm amazed at this carless design that was passed on to production. I don't know if this is also a problem on the five door model.
