I was looking through the 996 manual (Diagnostics part 2, 90-D132 page3) which shows the coding instructions for the instrument cluster, and came across the following:

"Cruise Control: This menu item enables the instrument cluster to be coded after replacing the instrument cluster or after retrofitting a cruise-control actuator."

There is another reference to coding after retrofitting the OBC. This being the case, I would have thought that Porsche would have issued a TSB about retrofitting. Do you know if they have done?

"porschelibrarian" is a member this forum. The manual has the updates and supplements up to February 2004.

The PST2 will give you extra information about the frequency of the fault, but ar3870 is right, you need to check the Porsche OBDII Manual for details of what to check. Unlike the code reader or scanner, the PST2 will also interrogate all the other control modules.

This Boxster Workshop Manual CD recently sold on eBay:

http://cgi.ebay.com/ebaymotors/ws/eBayISAP...item=8005597190

The price was $185.

This manual is exactly the same as the one offered by workshopmanuals.co.uk for only $20. The seller says it covers up to 2004, but in fact only covers 97-01. Someone has been severely ripped off, and I feel sorry for them. I don't want any of you guys to make the same mistake. How do I know it's the same thing? I fixed the index for workshopmanuals.

The quality of this CD isn't brilliant, but it is a good starting point for the DIYer, and at $20 you can't complain. However, I recently got a 996 manual from "porschelibrarian" and it is in a different league, much better quality.

Be warned of the eBay rip-offs!

On mine I had some play in the ends of the anti-roll bar drop links (item 19) which caused a 'clonking' sound over bumps, particularly when warm. Replacements were not too expensive. I also had a squeaking/groaning sound, which was simply lack of lubrication of the anti-roll bar rubber bushes (item 17). Some silicone spray solved that one.

Sorry, didn't see all your photos at first :oops:

Very Nasty!

Well, we had a frustrating day. I think the cruise will work OK, but the problem is the indicator light on the instrument cluster. This car has the later cluster with the new OBC display, and is radically different to the 2001 cluster. The wire which connects between Plug IV, pin 18, of the DME and Plug I, pin 16, of the cluster is not activating the cruise light. Also Fuse B7 is blowing occasionally. Obviously the connection to the cluster is wrong. Does anyone have a wiring diagram for a 2002, showing the DME and Instrument Cluster connections?

Tomorrow, I'm to help a friend with a 2002 2.7 Boxster cruise control retrofit. Is there anything we should be aware of that is different to Ed B's instructions?

Absolutely no problem. I'll PM you with my details.

Amongst other things, I have an Autoxray EZ-Scan 5000 which works well on my 98 996 C2. Other cars I have tried it on where it works well are an Audi TT and a Subaru Impreza WRX. A Merc A Class won't connect at all, and on a Peugeot 206 GTI it will read fault codes, but will scan a very limited range of sensor values. Overall, however, it is a good tool, and I bought it as it is CAN protocol compliant.

If you are ever in the area, I'd be happy to demo it.

There is an outfit in England ( http://www.perfectbore.com ) who make big bore cylinder blocks and pistons for the Boxster/996. There was a write up in this month's 911 & Porsche World about Autofarm in the UK who are doing a kit to go up to 3.8 litres. Pricey, though.

Where are you in the UK? I may be able to help - PM me.

There was a guy on the UK PCGB forum with a similar problem, see:

http://www.porscheclubgbforum.com/tm.asp?m=125090

He contacted Wilhelmy, and they told him to return it for exchange. I would suggest getting in touch with them

If he did I bet he had words with the guy who nudged him off!

I had the same problem on mine, and changed the plastic holder. What shocked me was the price of this item - (from memory) it was about 20GBP - that's about 34USD! I thought at first that I would change both while I had the roof strip off, but soon changed my mind!

I use Zaino Leather Cleaner Z-9 and Leather Conditioner (Leather in a Bottle) Z-10. Works great and smells fantastic.

(No affilliation)

M1 0W-40 is still freely available over here, and used by all OPC's. Personally, I run 5W-40. The cheapest I have seen M1 here in the UK was at Costco at 6.00GBP/litre - that's over $11.00!!!

I understand perfectly, and apologise for not consulting you first. I should have thought more carefully before suggesting it. I appreciate the marvellous job you do here, and would not wish to jeopardise your position in any way.

:oops:

In response to a PM on this subject:

The 996 manual I bought (on eBay) is a 2-CD set made by Lexcom in Germany for Porsche. It contains a menu system that loads when you put the CD in the drive, and an indexing system when Acrobat reader starts. The workshopmanuals CD has the same pdf files, but is missing the index system. I think they fooled around with the index when they introduced their banner on the manual pages, and it screwed things up. Judging by the fact that their web site shows it as 618Mb, I assume that they supply it on ONE CD, which could be the root of the indexing problem. They must have stripped out some of the non-essentials, because my CD1 is 712Mb and CD2 is 237Mb. My reason for saying the files are the same on my CD as the workshopmanuals CD is that the pages that Loren shows (above) have the same faults.

That was the problem I had with the Boxster manual I bought from them. I managed to modify the index files from the 996 CD's and put them on the Boxster CD to get the menu system and indexing.

It would be possible to re-create the 2-CD set with menu and index. You would need to separate the correct pdf files to two directories on your hard disk, add sub-directories to these containing the missing files (about 3Mb for each disk) and burn two new CD's.

If there is enough interest, I would be happy to supply the instructions and files to Loren to host on this board if he thinks it is a good idea, although copyright may be an issue. I don't know how renntech would stand on this, because workshopmanuals have probably breached copyright by supplying them in the first place.

If it is the same as the 996, the output voltages from the O2 sensors should be between 0.04 and 0.79 volts.

DME_Setpoints.pdf

The PST2 displays the Porsche fault codes in the fault memory. When you open the individual fault code in the program it displays the OBDII code and a lot of other detail - number of occurrences, check procedure, etc.

Thanks Loren, but I have a notebook system tester ;)

I am looking for a handheld device for quick tests on the 996 and other cars. Is the Davis system hand-held?

Edit:

Just found their web site. Interesting device, but not what I am looking for.

I have been looking for a handheld code code reader, and was tempted by the Equus 3100, until I found the Actron Autoscanner which displays live engine data as well. I know it is twice the price, but if it does what it says I think it would be worth the extra.

Anybody have one who can comment? Can you read MAF airflows and voltages, oxygen sensors, etc?

I bought a CD set on eBay made by Lexcom (the German company that make the PET). As Loren says, it isn't up-to-date, but it works for me as a starting point to use combined with the TSB's here. The pages have obviously been automatically scanned, and there are pages that are blurry. It can never be as good as a printed manual, but I find it useable. I bought a Boxster manual from www.workshopmanuals.co.uk and also had the "missing index" problem. I fixed that by using some files (which I modified) from the Lexcom CD's and it works perfectly.

Hi Jim

I had a creaking sound from this area which I tracked down to the sunroof mounting point, directly above the seat belt slider.  The torx bolt had loosened off, causing movement between the frame  and roof.

<{POST_SNAPBACK}>

Thx Richard.

I'll check that out...how do you get to it without taking off the s/room?

Jim

<{POST_SNAPBACK}>

If you take off the seatbelt mounting and slider, take off the slider/post cover, unclip the plastic cover at the top, you will see a torx screw holding the roof bracket. (That's from memory - it's late at night here!)

And the small rubber pieces under the rear windows? - I changed mine for the longer ones shown in the TSB - shame on you for not looking there first! :rolleyes:
