Hi all. I bought a 2017 L+K a couple of weeks ago. Today when I set off to work I noticed a knocking noise. Can't figure out where it's coming from. It's very frequent the knocking noise and not just when going over speed humps or uneven road. I've attached a recording to see if anyone could advise what's causing the noise before I take it back to where I bought it. The knocking starts around 30 secs into the recording. Any help is much appreciated. Thanks in advance. 

Welcome to Briskoda. 
We’d need some more information;

1. Petrol or diesel?
2. Engine size?
3. Manual or auto?
4. Mileage?
5. Hatch or estate?
6. Where is the sound coming from, so from the front, rear, side? 

Hi. It's a 2.0TDI, Hatch, 190. It's done 78k miles and is a manual. The noise sounds like it's coming from the front but it's difficult to be certain. I'll go out in it tomorrow and see if I can find out for definite where its coming from. 

Does it do it more when driving in a straight line?  If yes then I'd be looking at the roll bar links and/or bushes.

Or a duff DCC shock, as they have rattle issues when they've busted.  

Hi guys. I took it to the garage today. They put it on the ramp and found the left front link arm was loose. The link arms looked new so whoever put them on hasn't tightened it enough. However, what is worrying is that I bought the car 2 weeks ago and it only started doing it yesterday so, even though it seems it wasn't tightened correctly in the first place, it's worked it's way loose over the past 2 weeks. I'll see how it goes. Thanks. 

The looseness could be just that it was finger tight and use over a few days had worn the surface of the paint enough that it worked loose. Quite understandable really given the timeframe. Certainly not acceptable though.

This is what I found with mine...
