    Oldish thread but adding to it for moral support of others who may also have this question. My 1998 2.5l 5speed was also "missing" a bolt, lower right hand side just above the stud with the nut. Not sure if that's Wayne's D or G. There is a hole in the bellhousing rim and corresponding threaded hole in the engine case, but the surface corrosion of the case threads suggests there was never a bolt in there. Porsche saved a few pennies.

    So after a good long drive it's all running smoothly. No more cold start problem and idle when hot is smooth and consistent.

    Just to add, I left the airbag connected. Everything is accessible and there is slack on the airbag cable to cradle it on your lap that I don't believe you need to disconnect it unless you want to take the carrier frame out.

    I've just done the o-ring fix, worked brilliantly. Fuse back in, horn works evenly in all 4 corners of the wheel. My kids wanted to come test the horn too! Thanks Renntech members! There were 4 little washers under the carrier frame. I reinstalled these using a smear of paper glue to hold them in place while fiddling with the carrier frame and bolts. Order of assembly: washer, 1st o-ring, carrier frame, 2nd o-ring, 17mm bolt. For those in New Zealand, I ordered the o-rings online from Blackwoods NZ. They have all sizes and you can make up whatever quantity you need. And they are listed in Imperial sizes so easy to find. Cost $8.50 , about USD5.

    Great info here! I've just bought a 1998 Boxster with what sounds like this horn problem (previous owner says horn was sounding at odd times when driving, took the fuse out). Now just to find #31 O-rings in a metric country, or maybe that's a universal descriptor.

    Did you get this fixed? I was having trouble with car not idling at start up when cold. Removed throttle body and cleaned idle valve (1998 2.5l). It was gunked up and little metal "sliding door" was jammed. Got it loosened up well. This morning the cold idle is fine. But. After 10 mins of town driving it idled erratically and cut out several times. Took it for a good hard drive after which its running smoothly. If the erratic idle comes back my first check will be vacuum leak: during plenum reinstall I struggled with the thin pipe that slips into one of the rubber boots. Also re-used the gaskets... may be leaks there. Sorry for my long story and hijack. Maybe it helps. Regarding idle valve (IAV, ICV): what I learnt: to check its function, remove from TB, apply positive voltage to central pin and negative to either of the side pins. Small 9v battery is fine, don't need 12v. Valve should flick open and shut with one and the other. With no current applied, mine was open just about 2mm. Mine was seized up. Soaked with WD40, cleaned with cotton buds, jiggled witb small screwdriver until it came loose and moved easily. Hope you came right. Hoping mine's fixed.
