Sorry buddy - not I! Basically I always believed that the rattles were coming from behind the face vents in the centre of the dash - above or behind the MM.
On a lengthy test drive, the technician having sat both in the passenger and driver seat (obviously driving...) pointed out to me that the rattles were coming from the base of the windscreen area, largely around the passenger side. I agreed as it seemed to be throwing it's voice...IYKWIM!
It was at that point that I referred the engineer to the thread from matus and the white cloth.
I left the car with them, expecting them to have taken the whole dash apart, identify/fix and refit it. But on collecting the car, the technician had sourced and fitted the density foam. So it was nothing to do with me, other than to tell them about Matus's fix.
Hope this helps. Also, when you say the foam has deformed the vents, what do you mean? The foam is applied no where near any vents...
@ Lexusjohn - like I said in my note, this is a bodge up, but it works (largely). I think the new IS is either rattly or not, and at least I get some peace and quiet after a stressful day at the "shop". I just cannot be arsked anymore to keep complaining.
I would recommend anyone with problems to get Lexus GB involved, show them this thread, and point out that it is unacceptable. My car now is beginning to "crack" over potholes - cracking sounds from the centre console. It is definitley temperature related.
I think I actually finally know now that I wouldn't buy a Lexus ever again. But that is based on my personal experience of both the product and customer experience. In fact I wouldn't spend so much money on a car ever again - if Lexus cannot give us peace of mind then we have no hope!
Not good...not good at all.
PS - just to repeat - it was Lexus Leicester who identified the fix, sourced the foam and fixed it. the only thing I did was refer them to Matus's picture.
JambooIn an earlier post you mentioned having a rattle which sounded like a "sugar lump rattling around in a cup" coming from the dash centre - did the foam across the bottom of the windscreen cure this too? - I've got the same kind of noise coming from my dash but it seems to disappear once the car is warmed up.
