Hi all,

So when I start up my Golf MK4 I get this knocking noise coming from the centre of the vehicle, slightly behind me. I also intermittently hear this while driving too.

Just had new bushes installed but the sound still remains so I think we can strike that as a potential problem.

Could it be that the exhaust is loose? How would I find whereabouts and how should I secure it?

Thanks in advance for your help.

Steve

Welcome to GolfGTI,

Could well be the exhaust as happened to mine, get it on some cheap ramps, wedge the wheels with a couple of bricks and crawl under. Wobble the centre section and see if any part of your exhaust makes contact with the aluminium heat protector running down the centre of your car. If it does you have a worn or broken bracket or bush.
