The light came on, I hooked it up again, same as original and airbag lite keeps coming on???

you will need to reset the airbag light with PST2, PIWIS or durametric.

As far as I know...there's no way to keep your CF parts from cracking or delaminating, or turning yellow. It seems that it's more related to a run of CF because some of us have complete CF interiors and have never had any problem with cracks or other issues.....others report all sorts of problems. I'm wondering if perhaps Porsche contracted with different companies during their production runs and that perhaps some lots were of poorer quality than others. You may also have some sort of aftermarket pieces in there as opposed to factory....dunno. I never clean my CF with anything other than a damp rag....no chemicals, Armoral, or any cleaners....perhaps some of the cracking is due to a chemical reaction from interior cleaning products.

Do you have problems with other parts aside from the steering wheel?

Isn't it sun related?

Yes the shift **** and ebrake also have saller cracks. Stock pieces, I heard it is the cold that cracks them, heat would soften, right??

Logic would tell you that heat should soften them, and cold might cause them to harden and crack...but then again, heat would also soften the expoy in the glue that laminates them, causing them to split....dunno...a case could be made for either way. I've had my car out in the Sacramento sun all day...interior was so hot I couldn't touch the steering wheel and had to use a rag to drive it till it cooled off. I dont' usually leave it in the sun, but couldn't help it this time.....I had no ill effects from the heat....that must have hit well over 140 degrees inside the cabin.

Cold does not crack them

(at least not in my case)

2003 with no cracks in carbon, 25K miles, and left out in the sun many days. Odd, maybe it is certain batches.

2002 with 94,000 miles - purchased new in June '02, full factory carbon interior, no cracks or discoloration - in fact it still looks like new. I did have the side vents curl after a few years and they were replaced under warranty - no problem with them since. I leave it in direct sun all the time, but it does not see much cold.

2002 - tons of pealing. Car never left in sun, always parked in (heated) garage.

Zip: Was that car ordered with a factory CF interior? Are those OEM CF accessories in there or aftermarket?

You could always order new pieces if they crack

I've done some fiberglass work before and researched epoxy resins before buying them. These are the same epoxy resins they use when doing carbon fiber work - this is the clear plastic coated in and over the carbon fiber. Some epoxy will yellow and become brittle from UV rays (too much sun). You have to use a very specific epoxy resin that resists the harmful effects of UV, or coat the epoxy with a UV blocker. My understanding is that the Porsche OEM parts use an epoxy that is not very tolerant of UV and thus yellows and can crack. MA Carbon and other aftermarket suppliers however boast that they use a more UV resistant epoxy and thus make superior products to OEM.

I've got a CF steering wheel and other parts and I live in a part of California where the sun can be very intense. I ALWAYS use a sun shade in the front window if I'm going to be gone from the car for more than 20 minutes. I also garage my car and I park it in the shade at work. I do this to try to preserve the parts as they are Porsche OEM.
