I've had my 07 159 for a little over a week now and am really enjoying it but the creaky dash is beginning to aggravate my vehicular OCD.
I've done a few searches on this and can see that the windscreen seal can be a potential culprit, so I've checked and lubricated that which made no difference. I also see that others have complained about creaks, squeaks and rattles from the dash area.
The worst of mine is coming from right in front of me, sounding as though it's coming from behind the dials (speedo etc) it's a creaky / plasticy crack which happens over say a speed hump or turning into a roundabout, anything that causes the tiniest change of load on the dash assembly.
It is possibly heat related as if I blow cold air through the windscreen vents for 5 minutes it appears to improve (tho that could be my imagination) that said yesterday and today half way through a journey I realised it wasn't doing it at all, yet this morning on the school run I could have pulled over and taken a pick axe to the whole lot it was so bad
(at least it felt that bad on a Monday morning).
My gut feeling is that it is something to do with the plastic windscreen vents as if I apply pressure on them with my fingers I can sort of replicate the noise, as I can if I apply weight to the dash above the dials. So somewhere between my ears and the windscreen
I appreciate this a tediously dull subject and I don't expect anyone to tell me it's 'such & such' (unless you know what it could be of course) but some suggestions of how to attack and resolve the problem would be greatly appreciated. Has anyone else suffered from a similar problem and either resolved it themselves or had it resolved by a dealer? if so do you know what they did?
Looking forward to hundreds of replies
seriously thanks in advance if anyone has got any thoughts or experiences, it's a minor problem but bl**dy irritating in an otherwise beautifully crafted interior.
