Rear knocking noise over bumps

[flyingzard]

I had a similar knocking noise that sounded like it was suspension. There is an old thread in the (18 months ago now maybe).

Turned out to be a defective locking mechanism for the boot. Once that was replaced the noise never came back. I wouldnt be surprised that you have the same thing.

Hi mate I'm a vw mechanic to trade and there's a good chance that if the boot or parcel shelf removal doesn't cure the noise, the rear arms bushes could be worn, we've done loads at work. There not bad to do but you will see the 18mm bolts behind the rear anti roll bar and 21mm nuts and bolts at the hub end. You may need to exhaust slid to one side and definitely need to rear anti roll bar out the way to access them

Id take a guess at the bushes...use independants though..or ebay..should get decent ones for a good price..then find a mate who knows what hes doing to save the labour lol
