Creaky Headlining

[sutherland]

I have all sorts of annoying creaks that appear to come from my headling (02 D2) when as the car body flexes over bumps etc., but despite my best efforts I cannot track down he precise cause or location. I tried screwing down the sunroof frame a bit harder - no difference. Does anyone know a possible cause of this or can anyone provide me with the complete procedure for removing the headlining so that I can find the source and refix everything securely?

Thanks.
