Wind Noise Front Windows

Post by RP22 » Sat Jul 13, 2019 11:56 am

We have a 1.5 TSI SEL DSG, 2019 registered [UK]. Mostly we are very pleased with it, it is a really good driving experience, but……

At about 45 mph a wind sound starts on the driver’s window. The intensity increases until at motorway speeds it is really annoying, and tiring. The passenger side has the same sound, but at a much, much reduced level. I would like to find out what it could be before I go to the dealer. Things I have learnt so far are:
1. It is very different intensity on the two sides, as stated above
2. If you turn round and go back down the same road, the high level of noise stays on the driver’s side [i.e. eliminating wind direction]
3. Some web sites e.g. What Car do not report it as a problem, others do e.g. Top Gear. There are others on both sides.
4. This difference confuses me: I could understand different trims with different size wheels having different road noise levels, but I would have thought all T-Rocs would have the same windscreen, wing mirrors, door panels etc. So why should some T-Rocs have window noise and others not?
5. There are various suggestions put forward by web sites such as big wing mirrors, air hitting the windscreen and being deflected, air hitting the wing mirror posts.
6. I have used masking tape both inside and outside of the door frame but none of this made any difference. I have also taped around the wing mirror – closing off the channel that runs around it, to no avail.

If anybody has an inkling as to what is causing this or how to fix it, I would be grateful. It takes the edge of what otherwise would be a great driving experience. Thank you

Arghhh, so I’m not the only one! My first observation upon driving my T-Roc was how quiet it was... I suppose this is because my previous car had been a Tiguan 2.0 TDi with its inherent diesel sounds. As the T-Roc’s 1.5 TSi was so quiet the wind noise from what I assumed to be the driver-side mirror housing became evident. It starts as a hiss at around 40 mph and gets louder, but not too obtrusive... However I noticed that as I went faster this wind noise became less noticeable.
I can still say that the T-Roc is without doubt the quietest car I’ve had for some time and the fact that you can hold a normal conversation, without having to raise your voice at 70 mph, is a testament to this.

Same here, once I start to go above 40 MPH I get annoying wind noise, I now have wind deflectors and they make it worse , I also had noise from boot area but it seems to have lessened when I moved to boot floor to the higher position.
