430 Instrument Cluster Fascia Bloom

Something that bugged me since I bought my F430 - 5 years ago- was the unusual bloom on the Cluster Facia around the Dials.

I looked for any info on what is was over the years, and although I came across a thread about it there wasn't any resolution or idea as to what it was or caused it.
All that was apparent was it seems to be a common problem that inevitably ended up being left alone.

I resigned myself to the possibility that the finish would be beyond repair, and it would have to be re-painted.
Something I wasn't too enthusiastic about, but knew I would end up doing at some point.

So today I swallowed a brave pill and decided to get to the bottom of it.

Removing the Instrument Cluster was pretty straight forward, so no dramas there. However during the process I noticed the same blooming on the outside - which was hidden under the shroud - so I wiped it with my finger and it vanished, leaving the normal matt finish.

I was encouraged by this, and to to be honest couldn't wait to get the Cluster out and strip it down.

With the cluster out and on my desk I proceeded to strip it down. I found that the blooming was limited to just the matt black facia part and and mercifully not on the Instruments.

Fortunately you can remove the Tachometer's Bezel so you you are just left with the plain Facia.

I tentatively rubbed my finger on the blooming and it started to come away. Woohoo !
Then I gave it light rub with a microfibre cloth. Even more woohoo, but there was still a ghost of it.

I hot footed it down to the garage and grabbed some Meguiars Detailing Spray and a fresh Micro Fibre, then misted some onto the cloth and worked my round the Facia, then buffed it up with dry cloth.

And the result....................gone, vanished like it was never there !

I then went over the back side of the Facia and the rest of the Cluster removing any of this blooming.

With it all cleaned up I did my best to remove as many dust particles as possible - always a hazard when opening up these things - and re-assembled it.
I even had some felt tape I could cut to size to refresh the points that make contact with the leather of the Dash.


So the question is, what is it ?

It certainly wasn't any form of oil. The only conclusion I came to was condensation.
These units aren't fully sealed to allow them to breath, so over the years of seasonal temperature changes etc, a small amount of moisture creeps in and by capillary action ends up where it does.

As for the unusual patterns, that is most likely caused by the magnetic field generated by the five "Stepper Motors" that live inside cluster.


Anyway, I'm chuffed to bits with this afternoons tinkering. Just wish I'd done it years ago !

That is entirely possible.

 

Just follow this short video to remove the cluster......



I will point out it is five screws for the column shroud, and not six as quoted in the video.

As for stripping the cluster I just followed my nose.
It's not too complex.
