I picked up a car a month back. It is a VW Polo GTI and has covered 42k miles. It has been upgraded and lowered with Bilsteins by the previous owner.

At first I don't think this was happening, but over the last week, I have noticed a knocking sound which I think may be coming from the front. It happens at low speeds, and when steering, both forward and in reverse, and also happens on flat/smooth roads (no speed bumps/potholes). It is quite consistent and not too intermittent once it starts and something tells me it may be worse the warmer the weather.

Here is a small clip where you can hear it. Most noticeable 15sec onwards when the indicator cancels. https://photos.google.com/share/AF1QipPvPJ3xF6gGe-...

any ideas?

Can't really hear it but if it constant when turning it could be a CV joint.

About 150 quid for a garage to change it.

Check the strut top mounts and drop links.

If the frequency is proportional to roadspeed, you're probably looking for a damaged wheel bearing or CV joint. If it's affected by cornering forces, that would point towards the wheel bearing.

If the frequency seems independent of roadspeed you may be looking for a suspension problem such as a worn ARB drop link.

^^^^ Wot 'e siad.

On top of that some car's drive shafts don't like being lowered.

Minis are particularly prone to this.

Are they Bilstein shocks? Quite common to knock at low speed, just google ‘bilstein knock’

Could possibly be anti-roll bar bushes.
