Polo Gti 6R knock sound when reversing and turning

Post by G-VW-MK1 »

Hey guys ... so i have a bit of a problem . As you can tell by the title subject my polo is making a really strange knock / snap noise when and only when i reverse the car and turn the wheel . This does NOT happen when i reverse straight back . It also happens on both left and right turns of the wheel. i have taking it to vw and when i need to show them the sound its making the it doesnt freaking happen . Now from what i can hear its coming from under the dsg box or middle of the car and i have told them this . Now what i have found out is that when i leave the car for a while say over night then the next morning it happens without fail . I have recorded a video clip to show the vw guys as they cant seems to replicate the problem . I have heard it as well as family members because its quite loud at times . Any advice would be greatly appreciated .

cheers
G

Is the noise happening when you press the brake or just while you are moving ?

Only when reversing and turning? Nothing moving forward, braking or turning?
You have coilovers? As Ace said, maybe CV's but the car is way too young for that, else it might be a torn boot and no grease in there.
Other options could be a bad dogbone. Does the car hesitate to move in reverse or is there any jerking or vibration?

It only happens when reversing the car and turning the wheel . I do not have coilovers ... the car is stock as i just got it .
car only has 32k on the clock so not sure if its cv joints . The car does not hesitate to move back or vibrate . have a listen to the video and let me know what you think . oh yeah ... when i reverse the car i do have to apply a little brake otherwise i will reverse too fast .

I see you're in Cape Town. Give Mario at C-Teq a call or another reputable mechanic. Just to give you a second opinion. Something is definitely loose, just need to find out what.

seems after some research ... a couple of people with similar issues have said strut towner bearings o both sides fixed the problem . They also had the same problem that i am having when reversing and turning the wheel . Also i forgot to mention that the service guy did ask me if the brake feels sluggish because what tends to happen is the calipers dont release correctly when it should and then it creates that pop sound randomly .

EDIT: also mentioned was the subframe ???

Did you check the ARB and Bushes as well as the drop links ? Maybe disconnect the drop links and do a test to see if it eliminates the noise.

I have had that sound from car since new in 2011 and have taken back the car to the dealer countless times. My car is now 5 years and a month old and it's still there, so I all I do is turn up the bass.
