The emergency wheel for the 987 is option code 447 and has the same (03) part number. The emergency wheel also needs a compressor to inflate the tire. I doubt Porsche would have created a new part if the old one could be used. The 01 emergency wheel was used in the early model C4 and early C4S. You would have to test it to see if it would fit - both in the trunk and wheel offset. As of MY04 the C4S also uses the 03 wheel.

According to the parts list either will work. The 03 part is a newer design and according to the US retail price list $14 cheaper.

I think you will need one with a screw on hose fitting for MY02 and newer Tips. Otherwise the ATF will squirt out.

Since you are a Contributing Member you can see the all the part numbers and install in TSB 3/00 6315 Installing Cup Aerokit (dated 7-21-00).

You can readout the error code with a PST2 or PIWIS tester. Chances are it is a bad microswitch on the front trunk (a known problem which there is a TSB for), or oddments tray microswitch or the rear trunk microswitch.

Could be a bad sender if it doesn't go out after starting (cold).

Hi,

Sometimes the tiny red warning light on my temperature gauge doesn't go out after the engine starts. If I turn the engine off and restart, it goes out. All the other lights go out fine. The car is cold.

Anyone know why? Should I worry? Is it easy to fix? Is it a sign of impending doom?

The car is a 98' 2.5

Thanks

The Davis CarChip is a recording device. You plug it into the OBD II port - drive around then remove it and download the info via USB to a computer. More info here.

Well, if you have a laptop computer I like Car-Code as it can give real time and recorded plots of MAF, O2 sensors, coolant temp, RPM, etc., etc. At $120 for the software and cable I have found it hard to beat.

I have a Davis CarChip EX that I am reviewing now. So far it looks like a good recorder (of up to three monitoring systems) but pretty limited as a diagnostic tool.

WaterWetter® is a unique wetting agent for cooling systems which reduces coolant temperatures by as much as 30ºF. This liquid product can be used to provide rust and corrosion protection in plain water for racing engines, which provides much better heat transfer properties than glycol-based antifreeze. Or it can be added to new or used antifreeze to improve the heat transfer of ethylene and propylene glycol systems. Designed for modern aluminum, cast iron, copper, brass and bronze systems. Compatible with all antifreezes, including the latest long-life variations.

It's covered in TSB 5/03 6658 Aerokit "Cup II" Installation Instructions (dated 5-23-03). Did you get the kit with wiring harness, and other parts or just the wing?

Without the switch the PSE will be always on. No problem as long as you stay under 4000 RPM in quiet zones.

A6 should be CAN high and A14 should be CAN low. A5 is electronics ground.

On GT3 rotors the cooling vanes (inside the rotor) face opposite directions. It is possible on a GT3 rotor to put them on the wrong side - creating little or no air flow through the rotor.

If the Brembo's are all the same then it likely does not matter. I would check and see if they are marked L and R or if between two they have different part numbers (front and front and rear and rear).

There is no self-leveling for retrofit Litronics.

7.5 ft-lbs (10 Nm).

If the Brembo J slots are like the stock GT3 rotors then make sure you put them on the side or brake cooling will be non existent.

I just bought a 2000 996 and the unit works fine, but the station buttons are damaged, so I bought a replacment unit on Ebay.

I have a carbon fiber interior, I can't see how to release the existing PCM to pull it out of the dash.

How is unit revoved?

Thanks

Yes, bleeding the clutch on a GT3 is the same. I think the slave cylinder bore is just a little larger on the GT3 - but it functions the same.

I clicked on the download this morning, took me to a page for payment, picked paypal and payed.  Then nothing.  I contacted the customer service as to how to download, nothing.  Good thing I used paypal, and can get my $$ back worst case.  Did I miss something on the download?

I purchased and downloaded a copy of the 996 manual from www.workshopmanuals.co.uk. I compared them against my factory paper version (which includes all of the current supplements).

The downloaded manual appears to be a 1999-2000 vintage and the newest supplement (that I could find) it has is 39 (current supplements in my manual are 95). That means that the manual is only current through early MY2000. The wiring diagrams confirm that also as they only go through 1999.

I did not have any problems opening the PDF files but every file I opened did complain of a missing index - which means you can not search across all the files with Acrobat's search function.

The quality of the scanned pages is okay at best. Some images are a bit fuzzy and broken up (see below).

Oddly enough they also threw into the General section the Service Information Technik Books from MY2002.

Since the quality is poor, it does not cover C4S, Targa, or GT3 mk2, and this version does not have the additional supplements I can't recommend it. Even for only $20 much of the information is outdated.

Correct on the Litronics upgrade (even from a dealer) you do not get self leveling. on the (MY02 and newer) Bi-Xenon you do.

Have a look at the DIY section... this is a 15 minute job (drain time is 20 minutes). On a scale of 1 to 10 with 10 being the most difficult this is barely a 1.

You will also save few hundred dollars. Or better yet come to one of our Bay Area work on cars days and we'll help you!

Excellent! :D

You will need to put a OBD II scan tool on it to see if it is generating fault codes (not all fault codes turn on the CEL). The better tools will actually graph the performance of key components (like the MAF, fuel trim, O2 sensors, etc.).
