I can tell you that my 996.2 had those exact symptoms and no CEL. Replacing the vent valve at the filler fixed the problem. I can't say how your car differs from mine, except that I would rather have yours!
rockhouse66 replied to Citgot's topic in 996 Series (Carrera, Carrera 4, Carrera 4S, Targa)Keep an eye on the O2 sensor cables when dropping the engine down to be sure they don't reach their limit of travel.
I have a similar situation as Mr. Whitney. My 2004 996 originally sold in Canada has the fog lights on all the time. I removed the relay to kill them (permanently) but would like to return them to switchable. There is actually a wire cut at the headlight switch that I suspect is the fog light wire.
My spoiler is a factory XAG option code, described simply as "Carrera Spoiler" on the build sheet. Looks like this:
I don't mean to start an argument with this, but just adding some info. My '04 Cab has the optional factory side skirts and rear wing. I have studied the 2004 Cab option list and apparently no front spoiler was available so this is as close as the original purchaser could come to buying an "aerokit" for this car. Porsche must have considered this combination of parts OK w/o a front spoiler. I also question whether the aero imbalance issue is relevant at normal speeds and might only come into play at Autobahn speeds (as in 100 MPH plus)?
Is the system the same as on a 996? If so, the most common cause seems to be the vent valve contraption just below the filler neck. I had the same symptom and replacing this vent valve fixed my 2004 996. Mine didn't throw a CEL though, just wouldn't start after fill up.
Yeah, me too! The car is still on the lift and messing around at the front I think the RF wheel bearing needs to be replaced. Sounds scratchy when spun (and no, it isn't dragging on the rotor - this is with caliper/rotor removed). So, I get to use my tools again. And this should be a piece of cake without the drive shaft to deal with.?
OK, I am all done except for final torque on the axle nut. The tools worked fine. The job, as a whole, was a physically tough PIA for me. Working the axle shafts out and back in, dealing with the hub removal from the bearing, etc. This is working alone but with a lift. If this really is a 2 hr. per side labor charge at the Porsche dealer, I would recommend just paying them to do it. I would love to watch this job done in 2 hrs. per side. BTW - would it be good practice to put some anti-seize on the axle threads or just leave it dry? 340 ft-lbs seems like it would like some lube.
Yes. Works fine from the switch. Windows go up after about a 2 second delay.
Excuse my impatience, but no thoughts on the fix for this? Or maybe my car never had this feature (though it appears in the owners manual)?
It would be really convenient to be able to exit the car with the top down and close it up completely while standing at the door. I would like to make it functional if I can figure out where to start. I suspect it could be something in the door lock itself, or maybe in the top latch or even the dash button area.....?????
I think that when I raise the top on my '04 C2 Cab using the key in the door, at the conclusion of the top locking process I should be able to hold the key in position and raise the windows. Right? Mine won't do that, though everything else about the top and window operation functions as it should. Where should I start to troubleshoot this?
Well, right or wrong, I bought the CTA 8650 tool kit, which I think is a knockoff of the SIR kit. It was under $300 delivered. I have also purchased the bearings from Sunset to do both rear wheels. It will be a while before I get to this project but, when I do, I'll provide some feedback on the tools and anything helpful to future DIYers that I learn. Thanks for the input from members.
Nice tool. Are either of you suggesting that the work is best done with the upright off the car plus a small expensive pile of pullers? It does look a little involved to be doing on the car but I thought that was the point of the SIR tool set?
