Hi
@Kieron101 .
Sounds like you have the common windscreen "Cracking / Creaking Noise" that some other owners ( including myself ) have witnessed.
Does it sound like the front of the dash panel is "Rubbing" on the inside of the front windscreen ?.
If so, you will find it is much louder and annoying when the weather is really cold, but the creaking can be heard as the car moves over rough covered tarmac.
If this is a "Tick In The Box" for your car, it is likely to be the cause.
Go outside of the car, look at the bottom of front wind screen glass.
There is a black plastic scuttle panel that stretches from one side of the car to the other.
You can see where the two wiper arms pass through this plastic panel.
See it !.
Right, now look where that plastic panel meets the front wind screen glass.
Can you now see a black rubber / plastic type gasket seal that bridges the gap between the edge of the scuttle panel and the glass ?.
BINGO - That is the cause of your creaking noise in the car.
As the body flexes, the plastic / rubber gasket is the problem.
Your next quest is :-
"How do I fix it then".
Here are your options, take it back to the dealer of course.
The second option is a quicker fix, if you feel okay with it ?.
You need to get some type of lubricate behind that seal to reduce the friction / foul condition between glass and gasket.
You need to create a small gap in order to use the nozzle from a spray can of anti friction lubricate in there.
WD40 will work, but only for a couple of days.
A silicone spray or a dry spray lub should do the job.
WD make a can of white lithium spray that is a pretty good fix ( ask me how I know ).
You need to get that nozzle behind the gasket and go right across from one side to the other, no gaps !.
To help getting the spray can nozzle behind the gasket, use either a plastic trim tool or an old plastic membership / bank card.
DO NOT USE ANYTHING METAL LIKE A SCREW DRIVER PLEASE !.
you will know straight away if it has worked when you take the car out next time.
Is there a better long term fix ?.
Yeah - I do think there is to be honest.
But this involves a lot more work.
Very briefly, it goes like this :-
Remove the wiper arms, remove the rubber bonnet seal, remove all of the trim clips and fasteners that secure the scuttle panel.
With the scuttle panel completely removed from the car, clean and install a strip of silent tape right across the windscreen gasket.
Refit the scuttle and your done for a long term fix I think.
The spray method works about 99% effectively, but you may need to repeat the process again is the lub drys out !.
Good luck !.
