Hi,

I've got a 2017 F-Type convertible - new to me - and am experiencing wind noise from the front passenger side when going >60km/h. Sounds like a window is down, not a high pitched whistle. No air seems to be coming in, took it to the dealer, they suggested replacing the seals which I did and found a hidden crack in the windshield which was then replaced. The noise persists. Audible with both the roof down and up. Does anyone have any thoughts?

Thanks!

 

does it have the wind deflector fitted?

 

No there is no wind deflector. It sounds like it is from the front corner, I would have expected that if it was wind deflector related it would go away with the top up.

 

Try pulling on the door handle when you hear the noise. If the door on that side isn't properly adjusted, that's all it would take.

 

You can try resetting the windows. My notes show this:

Close the window fully and release the switch
Lift the switch to Close position and hold for two seconds
Repeat 5 times

I thought there was more to it, but didn't update my notes after the last time I did it. I think there's some quirk, like the engine having to be running. Searching here should turn up more information.

To diagnose reported problems like this "back in the day" I'd occasionally do this:

My mechanic's stethoscope, with the probe removed, has an end like a small funnel. Engine off, heater fan on full. Close the doors and check the edges of the windows with the funnel end. Alternately, a piece of rubber or plastic tubing, maybe 1/4" ID or so will work. Hold one end near (but not in) your ear and do the same.

That should at least locate the spot. It might be an adjustment is needed on the window mechanism. I haven't had to do that, so am not sure what adjustments are available.

 

Hopefully it will solve the problem, but if not, I have noticed a couple of times that my hood does not latch down tightly on the driver's side.
Solution was simple - just push it down harder when closing.
So, you might check to make sure that your hood is closed firmly on the passenger side.
Lastly, have a passenger run their hand or a fine silk handkerchief (!!) along the sealing edges of the door and window to see where/whether there is air ingress when moving (faster the better!!)

 

I reset the windows, also pulled on the door, and double checked the hood. The door is solid, the hood is latched firmly on the passenger side. There doesn't seem to be any air coming in. The noise is still there.

I also thought it might be the HVAC system, removed the cabin air filter and plugged the intake with a towel, no change. Unhappy

 

Have you tried putting tape along the various areas where the noise might occur (one at a time!)? Time consuming but may help to identify the errant area.

 

I've just realized that the noise you're asking about is audible with top up and down. Most of the techniques mentioned are to find sources of noise in an enclosed cabin. With the top down I'd expect wind noise, so not sure where to go next. Perhaps someone with a convertible will provide other ideas.

 

Yes, tried taping all the windshield/window/door/trim seams to no avail - was going to remove one at a time once it went away. Currently wondering if it is a loose panel somewhere. Also was reading this thread https://www.jaguarforums.com/forum/x...-2006-a-61208/ and this one https://www.jaguarforums.com/forum/f...-speed-164735/ as the symptoms sound familiar. Ordered a stethoscope should be here Wednesday.....

 

I'd expect wind noise also . This is more of a low frequency sound - been driving a 370z vert for years, I'm used to top down noise, this is different. More noticeable with the top up b/c the rest of the cabin is quiet but still distinctly there with the top down.

 

Any chance it’s tire related?

 

Its possible, dealer is going to look at it again - I might get them to swap the front two tires and see if the noise moves. Additionally it goes away at highway speeds when drafting a large vehicle - so I doubt its tire - but I've been wrong before.

 

Could be wind rustling over something underneath the car (loose panel, etc.) that is hanging down in the air stream. Everything can look tight when examining it static, but wind can move things at speed. Drive down the highway and have someone follow behind you and see if they can see anything moving underneath. Then have them pull along both sides of the car slowly at speed in the next lane and see if they can see anything moving.

 

Thanks everyone for your help. Looks like I have found the problem - tested with a little duct tape and it seems to go away. Working with dealer to find a suitable resolution - short version is 1" x 4" hole in undercarriage about 1ft behind passenger wheel. Will post pics and resolution once finalized.

 

Wow - that's some great detective work. Hole meaning you hit some road debris at some point?

 

Not me. I expect the previous owner either hit a tool or perhaps had an incident with a jack - and hole meaning tear/puncture in subframe... body shop says they can patch it - waiting on details

 

Ouch! I can see making that mistake with jack placement, but not disclosing the issue prior to sale is downright despicable.

 

I used different words, but despicable fits too.
