2007 sport 3.0 tdi front end knock

[Joe2.0E]

I have a 3.0TDI D3 with 205K miles and rising. The Drop Links/C-shaped links that are attached to either end of the Anti Roll Bar would be the first place to look, I have had them replaced twice (£65+vat for the pair).
The lower arms with the track rod end have also gone on mine over the years but the noise would usually be on the left or the right but not both together.
The 2 bushings on the centre section of the Anti Roll Bar also cause the knocking you describe but you would have to replace the complete Anti Roll Bar (£146+vat) as these Bushings are not available separately.
One way to eliminate some of the options is to temporarily remove the Anti Roll Bar (Only 4 Bolts) and road test without it fitted. If the noise is still present, its back to checking the upper and lower arms which are all mega ££ for Genuine parts.
