Dashboard knocking noise

Howdy folks, my TDi is making some strange noises from behind the dashboard area. when I start the vehicle there are creaks and groans from behind the dash and within 5-10 seconds I get a rhymtic knocking noise which repeats about every 2-3 seconds. This happens whether the a/c is on or off and only goes away once the engine is turned off. It doesn't happen when the ignition is switched on but the engine isn't running. The EGR valve 'moo' is a little more noticeable recently but other than that the car runs fine. Any ideas?

Also, is there a how-to guide on changing the fuel filter on the TDi available?

Thanks

Mike
 
Could be the wiring loom fixing? I know on the first A2 I had the same knocking problem and I think it was a fixing. I got it done under warranty - but that was 7 years ago!

Others can help I am sure on the fuel filter - best of luck as this is a 'pig of a job' on the earlier cars normally done after 80K
