That's trouble. Recheck connections. Use Deoxit on the plug-in connectors. Use fine grit sandpaper (and clean off the grit left by sanding) on the nutted connections. Is it possible you shorted something out as you removed the battery? Were the battery cable ends removed at the battery? Is it the original alternator? It might be possible that it's only the voltage regulator module. -
What are your voltages? Resting, idling, driving above 2000rpm? There are gizmos to help with this monitoring - Antigravity Batteries has a battery tracker. Others plug into the cigarette lighter. Do you have any codes (can be read with Durametric and other (OBDII) readers)? I've read stories on Rennlist about induced electrical noise in the sound system even when the sound system is not turned on. Might your alternator be damaged or no longer have a high quality ground? Could the noise be mechanical (transmitted noise)? You did change pulleys. Run the car a few minutes without the serpentine belt and see if the noise is reproduced.
-
Can you temporarily disconnect the new LEDs and see if the error codes are eliminated? New codes might pop up due to the lights being disconnected...
-
That could be. Also, when the previous battery was failing, its low voltage periods could have affected certain modules.

My 2005 C2S 997.1 key fob does not have the button you are pointing to. It just has the other two positions/buttons. Maybe your key fob is not original and the car does not support that fob button. I'm not sure.
-
Regarding #1, I should have read more closely, my key fob remote only controls the frunk lid, not the engine lid. Regarding #3, you will have to identify every area (glove box, door, frunk lid, etc.) that has this type of sensor. You'll probably need a wiring diagram. Then you'll have to test each area's sensor/switch. The Porsche service manual may have a diagnostic procedure - you may want to acquire (an "aftermarket") one.
-
Did all these things work ok before the battery change? Regarding #3, this usually means that something has been left open that should be closed. It may also mean the closed-opened position sensor for those areas is defective. Regarding #2, changing out the windshield fluid pump is relatively easy. Or, you could test the existing pump by bringing in 12v temporarily. I don't have experience as to whether a common control module might be the culprit for all three issues.
-
Is there any up trend in wear metals? What temperature zone has the car lived in? Any unusual oil consumption? Do you have sooty tailpipes? Inspect the spark plugs, anything oil fouled? If you remove the spark plugs, you can do a borescope but it might be less effective than one done via the sump. If you remove the spark plugs, you can do a compression test to see if rings or valve guides might be involved. Any pending engine trouble codes? What oil do you use?
-
I don't know if this will be helpful but I've attached a wiring diagram. You'll notice elongated ovals with text, for example, WL REAR. I presume WL means wire loom and REAR means the relative position in the car. 997.1_Wiring_(MY06).pdf

997.1 Need part number for insert for bumper cover
jchapura replied to jchapura's topic in 997-1 Series Part Number Requests
I found the part number. None of the three dealers in the area had the part so I'll be ordering online. The part number is 999 591 329 01. Here's a pic. It fits into the square hole in the second pic.

997.1 Need part number for insert for bumper cover

Thanks Loren! I'm standing at the Porsche Tacoma parts counter as I type... -
2005 C2S Coupe 6MT I needed to remove the front bumper cover to install a new HomeLink module. A couple of lower bumper cover mounting inserts and screws are sheared off. I'd like to replace them. I'm pretty sure the screw is part number 99907322709 and it's the fastener that takes a 27 Torx. (There are a few smaller fasteners taken out to remove the bumper cover that take a 25 Torx and I believe their part number is 99907323109.) Does anyone have a part number and supplier for the larger fastener insert that goes in the (lower) frame for a 997.1? The inserts are square with ears and fit into a square hole in the black frame. Attached is a pic. If the insert is not available separately, is there an alternate way to secure the front bumper cover?

2005 C2S 997.1 I just changed my fuel injectors and want to check for fuel leaks before starting the engine. Does the fuel pump activate with the key in the key on position? If so, does the pump stay on in that key on position, or does it time out if the engine doesn't start? I have a Durametric if that's needed to have the fuel pump stay on for 10-20 seconds without starting the engine.

How did your shop visit turn out? Were they able to diagnose the issue?
-
If it's a dealer or a Porsche-focused independent shop then they will have the PIWIS. It might be as simple as a couple of connectors not making the best electrical contact. You could locate connectors along the light's electrical path and then undo them and spray in some Deoxit and then plug/unplug/plug them a few times.
