Does anyone have any idea about the cause of a (very) rapid knocking noise when turning, both ways, at low speeds?  It's a 2015 plate Octavia with about 18,000 miles on the clock. I managed to get it on video.  You'll need to turn the volume up full to hear it.  You can hear the rapid knocking when making a left turn at about 40 to 45 seconds in to the video, and more clearly when making a right turn at 1 minute onwards.  

 

In both cases the speed was low, about 5 mph, and it's just turning (not braking or on the gas).  It was not on full steering lock; it was maybe 50% to 75% steering each way.  I've booked it in to the dealer to get them to have a look in about two weeks time (the earliest I could manage).  Anybody got any thoughts?  I think the knocking is also there at higher speeds but it's very hard to hear above the normal road noise.

Cannot help you, bit mine does the same and it has been doing my head in.

 

When you find out, please post here

Welcome to the forum.

 

Why not have the Master Tech @ Skoda Specialist Cars part of the John Clark Group have a Road Test in it, and if there is any issue that will be covered by the Skoda 3 year warranty they will be able to have a repair carried out.

It's booked in with them the week after next (would have been sooner, but I'm away next week).  The Master Tech there seemed a really good guy when I dealt with him a few years ago.  Hopefully the car will misbehave while they have it and they find the problem. 

I just wondered if anyone else had had a similar issue?

Sounds like constant velocity (CV) joints to me. These are the drive joints connecting the drive-shafts to the front wheel hubs. A little unusual for both sides to fail at the same time though. What mileage has the vehicle done?

Is the noise worse on full lock at very slow (crawl) speed, and is it noisier on one lock than the other?

Just over 18k (and 18k easy going miles too).

It's perhaps slightly worse turning right than left.  And it makes no difference if it's on full lock, or 50% of full lock, 30% etc.  In other words, it sounds just as noisy regardless of how far the wheel is turned.

But no noise when the wheels are straight ahead - is that correct ? If so I'd suggest getting the CV joints looked at. Is the car still under warranty ?

Be aware, that CV joints are most likely to wear when you accelerate hard on full lock.  Least likely to wear when steering is straight ahead.  They are often hammered when you have been waiting at a 'T' junction to turn right, a gap opens up, you put your foot down to get out into the traffic, while at the same time the steering is almost on full right lock.  If you search online for images of CV joints, you'll see why they are most vulnerable under these conditions.
