I notes on may 23 cayenne looks like suction cups mark on windshield .it was there when I picked up car new.I was assuming it needed only cleaning




,but didn’t go away.easy to see in the night driving underneath street lights,I have appointment on Saturday with shop manager at local Porsche.do any of you have similar situation. Thanks

 

between the glass panes? they would need to warranty that windshield if that is the case. I want to say i have faint ones in my 2024 but i never thought to check if they are between the panes.

 

Don't waste your time going to the dealer. There are products to polish the glass and remove such marks. Here is one of them.

 

I had the same mark on the w/s of a 958-gen Touareg for the 8 years and dozens of washes using cloth and glass cleaner. No change. It didn’t bother me.

 

Well, that's helpful.
Definitely have it checked out as that would annoy me, especially since it looks to be in your line of sight. You said it's a 2023, did you buy this as a CPO?

 

What I propose is not for cleaning the glass but for polishing it. It removes all traces of suction cups and other indelible dirt.
I had some mysterious inscriptions on my glass that were visible only when the glass was wet and no agent, including solvents, was able to remove them.
Only polishing the glass with this Sonax car glass polish definitely solved the problem.

 

Try using a good glass cleaner + Mr. Clean magic eraser

 

My car is still under factory warranty until October 25 (I took delivery on oct 22)and yes it is very annoying specially in the morning on the sunrise is most visible.I try to clean with many products but it is between the glass also I do have noise insulate glass

 

Mr.clean didn’t work for me

 

Well, then I'd take it in and let them sort it out. If it's in between the layers, it should be a warranty item. I'd be prepared to answer the questions, "how long have you noticed it?" and, "why didn't you notify us earlier?"
Otherwise, maybe a rock will hit it on the highway.

 

Dawn dishwashing soap.

i have seen people use a cut up potato to wipe it onto the glass surface and then wipe off soon after.

 

Quick update
After taking what service manager about suction cups mark he also pointed out that windshield have waived lock that isn’t wright .So he will order new windshield and it will covered by warranty
