2009 D3. Water leak into boot

[HootingOwl]

Unless the previous owner ticked the in-boot hot tub option, I have a substantial ingress of water into the wheel well.  Most of it appears to be coming from the rear windscreen, passenger side {RHD UK car} and then soaking through the parcel shelf.  I am going to strip the trims back next week for a closer look, but has anyone else experienced the bonded windscreen seals failing or is it more serious like a body seam? 

Thanks

Hello Peter,

Is the car new to you, or has it suddenly delevoped this leak?

Kind regards,

Gareth.

Car is new to me.  Got it last October and it appeared dry and did not smell of damp.   Bought from a work colleague of my Brother with a good and known history. 

Noticed the damp about 2 months after purchase despite some heavy rain. 

I took the rear headliner trim off and there was moisture behind it.  Will take down remaining trims this weekend to inspect further. 

Whilst driving along the M6 at a decent pace, I noticed a loud whistle coming from the back window... It sounded like sooty and sweep up to naughty things...  Makes me think that the seal has been breached. 

Looked at the parts and it shows a moulding strip at the top of the rear screen.  Going to fire up elsawin and look at the replacement procedure. 

Fingers crossed....

Update.. Just in case anyone is suffering from insomnia.  Pretty certain it is the rear window bonding.  If I push on the inside of the glass at the top., the screen moves outwards away from the body.  This cannot be right.  Further stripping back and new gaskets on order.  Windscreen fitter will be summoned when foam lays and rubber gaskets have arrived. 

Car breezed through MOT the other week but needed 2 new tyres.. Have a camber issue at the front but the excellent specialist I use knows how to manipulate the front subframe to sort the geometry out. 

Had the wheels refurbed in Audi Anthracite...

Glad you think you've found the cause. Just out of curiosity does the d3 have a sunroof? 

If so you may find one of the drain channels blocked and could possibly cause ba leak into the cabin. 

Cheers

 No sunroof.  It is almost certainly the rear windscreen.  I have stripped the trims and can see evidence of water ingress, and the screen can be pushed out from the body by hand.

This also explains why there is a high pitched wind squeal at speed - sounds like Sooty and Sweep going at it hammer and tongs.

Yep, certainly sounds like you've found the culprit then.
