Came across Vesku's fix for the infamous 159/Brera dashboard rattle, and thought I would have a go.
This has completely cured the rattle / resonance noise
I have been having since day one. I know others advise silicone lube on the rubbers, but this solution permanently eliminates the root cause
of the problem; namely the windscreen trim holding clips resonating through to the dash. So thankyou Vesku !
Took a few pics along the way, hope this helps other owners out and encourage them to have a go themselves.
- Flat bladed screwdriver, torx type socket set, 14mm (I think) socket to remove wiper arms, textile/gaffa tape, silicon sealant.
Step One - Loosen (dont remove) corner trims
Remove torx screws securing corner trim pieces (Do not try and remove the trims - you will break them, just leave in situ)
Step Two - Remove wiper arms
Remove windscreen wiper arms, pop off the rubber caps covering securing nuts with a flat screwdriver, undo nuts, there will be thin washer which is easy to lose. When pulling arms off their hubs push the arms flat towards the windscreen which will allow you to slide them off easily.
Step Three - Remove large engine bay / windscreen trim
There a 5 plastic snap fixings, these can be gently levered off with a large bladed screwdriver.
Once these are free' work the corner pieces free (loosened in step one), you should then be able to slide out the large black plastic trim cover. This is in two pieces secured by a torx screw in the middle,
but there is no need to separate them. On the back of the trim piece are the offending clips
Step 4 - Apply silicone sealant to clips
Following Vesku's advice, I applied silicone to the clips where they meet the black plastic trim.
Step 5 - Apply tape to windscreen
If you are lucky you will see where the clips have made an impression on windscreen dirt, clean this off and I used a small piece of gaffa tape (2 layers)
to 'insulate' the windscreen against where the plastic clips make contact
Reassembly is the reverse of the above, take care when relocating corner trims. It was easy enough for me to do.
Check wiper position, I initially set mine a little too high ..
Enjoy the silence !
