Perspex Cover on Instrument Cluster
#1

After months of searching for the right car, i finally jumped in and purchased a 968 coupe. I have previoulsy owned a 1985 911 Carerra and am enjoying the practicality and driving experience of the 968.

The clear prespex cover of the instrument cluster has been scratched by incorrect cleaning by a previous owner (amongst other things). Have any members had success in polishing the perspex? I note via a general Internet Search that Brasso or Maguires Plastic Polish are suggested.

Many thanks for any experiences or ideas.

Welcome and thanks for posting.

Many of us have used Novus polish. It comes in 3 grades depending on the severity of the scratches.

Tell us more about your car (codes, features, etc.)

Jay

I have the same problem in my clear plastic that covers the speedometer but there is actually liquid drips on the inside of the plastic were the previous owner must of sprayed the cleaning allot. Does any one know how difficult it is to remove the clear plastic and install a new one? I have asked the dealer and he didn't even know if it is one piece air sealed that the gauges go in or if I can just replace the clear plastic. Thanks for any info [img]style_emoticons/<#EMO_DIR#>/unsure.gif[/img]

Hi,
The instrument cluster comes off as one piece and the front cover can be removed easily. It is not air sealed.
Check this site for details. You could probably get the info from a post involving replacing a broken gear in the odometer.

Basically you disconnect the battery so the airbag will not trigger the RED light at the top of the cluster, because it can only be turned of at a dealer or PM.
Remove the wheel so that you can get the cover and cluster out. Some say that it is not required...I have never been able to do this job with the wheel attached.
Unscrew the large black plastic cover that surrounds the instrument cluster and the center heater/ac vents.
The cluster is held in by screws and hooks up with, i believe, 3 connectors.
Pull it out, open it up and have fun.
Plastic scratch remover that is mention earlier in the post is the best. I have used it with excellent results.
While out, you might get some lamps and change all or the ones that are burned out.

Thanks Jay,

I have a seal grey 968 Coupe with black interior. 92 build delivered 93. 6 speed manual with 150Kms on the clock. In very good original condition but it has the following little issues that I will need to attend to:-

1. Rubber body seals. I read a great instruction guide on the forum.
2. Minor delamination of the rear window. I at first thought that this was simply the black masking paint but I will need to investigate further. No leaks so I will probably leave this alone after reading about the issue on the forum. Bit of a nightmare problem.
3. Scratched perspex cover as mentioned above.
4. Rubber on bee sting aerial is degraded. I have patched this up pending sourcing a replacement. Can't seem to determine if this is a standard item or an Australian modification.

I had the cam shafts replaced as part of purchase and it has good cam belt and service history, so I have my fingers crossed for a great relationship. Kids love going for a spin so we are all smiles right now.

Regards,
Peter

whisker,

Welcome and enjoy your car!

There are quite a few posts about the instrument cluster...search for odometer repairs, light bulbs, etc. and you'll find a bunch of stuff. Although it's tremendously easier to remove the instrument cluster after taking off the steering wheel, you do not have to remove the wheel. The first time will be tricky, but it is doable. By not taking off the wheel, you don't have to worry about air bag issues and other steering wheel related stuff. You'll get the dreaded airbag light if you turn the ignition ON or start the car with the instrument cluster disconnected, so that's where to be careful. A good checks and balances reason for disconnecting the battery!

Once you go to the effort of removing the cluster, as others have mentions, there are lots of little things to do while it's out that will put a big smile on your face upon reinstallation. Good luck!

I ended up only being able to source Meguires Pespex polish. It seemed to work well.

Thanks for the advice from all those who responded.
