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.

Thank you Barnaclebob and troc-on for replying. I have never been in/, or posted to any forum before and I am surprised at the very few replies I have had. Different priorities, I suppose. I tried driving round with the wing mirror post wrapped in cloth and taped, but it made no difference. It was quite a crude experiment, so who knows. Thank you for the wind deflector information, I had been wondering about them. Money saved there. In our car, this wind noise increases the faster you go, no levelling or reduction. I am reluctant to take it in to the dealer because with the best will in the world having this and that tried doesn't sound too sensible. Perhaps I just have to wait and see if a definite answer appears.

Hi RP22,

Probably few people have responded because few have any experience of your problem. Wind noise is generally caused by air turbulence and the sound will penetrate into the cabin of any/most vehicles to a greater or lesser extent depending on design and quality of fit of the various components.

I suggest you contact your dealer and arrange to have a drive in another T-Roc for comparison. If that confirms that the wind noise in your car is clearly worse, then the dealer needs to examine the door in detail.

This would need to check that the door is correctly hung and that all the rubber seals are correctly fitted. Following that would be inspection of the window rubbers and guides, and possibly even the interior of the door behind the trim panel, where there might be some sound deadening material. The fitting of the door mirror would also have to be checked to ensure it is tight and any rubber seals between the mirror and the door are fitted correclty.

One other possibility is that the door window is not going fully up into the top channel and may need adjustment.

It is very much an inspection and trial and error approach, as you have already found from your own experiments, and the problem may lie in an area that is not readily visible. I can't see what else you can do besides what I've suggested above.

Thank you Impala for writing such a detailed, helpful reply. I am not entirely convinced about the low reply rate being because few readers have the problem. If you Google 'T-Roc Wind Noise' and look at the results, wind noise is mentioned as a problem on these websites: Top Gear, Motoring Research, Auto Express, Autocar, Practical Motoring, the Telegraph, York press, the Standard, the Express, Car Buyer, Press Reader, UK.Motor1.com - all these on just on the first few pages of results. The noises they describe sound very similar to the noise in our T-Roc

You are right that sooner or later I am going to have to go to the dealer, take out another SEL to listen for a comparison [noise wasn't present in an SEL test drive car but at a different dealer] and wait to see what they come up with. However, before I do that I am hoping that I can come across someone who had identified the problem and solved it.

There were lots of good points in your answer, Impala, I wonder if you have any thoughts on one more line of approach? - I understand Volkswagen produces something called Technical Service Bulletins [TSBs] when a fault and its fix is identified, as well as Technical Product Information [TPIs] for vehicle modifications. Do you, or anybody out there, know if these are accessible to the public via the internet, obviously for the T-Roc?

Strange that there should be so many magazine & press reports of wind noise being a problem.

I did a search of the forum and there are only maybe 2 or 3 topics in which wind noise is discussed, but not as the main subject. Impressions seem to be split 50-50 between very little and some noise from A-pillars or door mirror, but nothing major like you have described. Maybe you have very acute hearing and percieve this more than others.

Regarding service bulletins and TPIs, I don't think these are available to the public although, as you will find if you look at today's posts in the Kangaroo thread, they can sometimes fall into someone's hands. Your dealer should be able to chack and will surely inform you if any relate to wind noise.

Just a suggestion, but if you make up a solution of very soapy water, apply that with a sponge to both the door and window rubbers. If you then drive it immediately afterwards and the noise is reduced or has stopped, then the simple longer term fix is to spray the rubber door seals and the rubber seals around the window with Vertical Blinds Silicone Spray, as this will lubricate the rubber without causing damage.

It can happen that rubber seals dry out, and slightly catch - no let me term that better as do not sit properly once the door or window is closed, as they are insufficiently lubricated. Using a very soapy solution to determine if this could be the cause is a cheap way of determining the fix (as the lubricant from soap is only temporary), Silicone Spray is a more longer term solution.

If this is the case, then environment or other factors could cause rubber seals to dry quicker or slower, thus why some T-ROC's have wind noise, and some door.

Either that or it's a poorly fitted door, which the dealer would need to determine and sort

I am a troc 1.5 owner and am facing the same problem with wind noise over 80 kmph. I went to my dealer and asked him to drive the car and tell me for a possible solution. His opinion was that the pillars next to the windscreen create the wind noise because of the car's height.

Any solution would be a great help for me, cause in general it is a really good car.

So why aren't all owners complaining about wind noise :?: :?: :?:
I have to say my Troc is amongst the quietest I've owned over a period of approx 50 yrs even at 80 MPH (on the motorway - I was in a hurry :!: :!: :!: :oops: :oops: ) I do not get excessive noise. In fact, I find it a quite relaxing drive ;) ;)

Perhaps you're partially deaf as well as dangerous? Sorry, couldn't resist :D

Hello Stam, again. I am not sure about the noise being caused by the pillars next to the windscreen. If this was the case all T-Rocs would surely have the same problem, but what is clear from Interneting it is that some do and some don't have this noise.

Perhaps it's a 'heavy-breather' .. these roos can be quite excitable :!: :!:

I'm waiting for VW to issue a TPI announcing that the wind noise is due to flatulent owners who are advised to visit their Doctor for a software update. This is a known characteristic in all people apparently; an interim fix is a strategically inserted bung :mrgreen:

Hey T Roo,
Would not that cause a bit of tubo back pressure? :D

If you move in the city till 100 kph it is not so annoying, but if you move mostly in the highway at 130 kph it may become really disturbing..

I ll try a door alignment and inform you about the results.
