Durametric and OBC on a 2001 S

[Pdwight]

OK I got a Durametric and tried to enable my OBC today and I get an error. I then check the OBC with the Durametric and it says "OBC already enabled" ??

So I disable and try to re-enable and get teh same thing ??

Anyone else have this issue, BTW I have the newer style of Instrument Cluster

The OBC is like a light bulb, it is either on or it is off; yours must already be enabled.

Do you see an outside temperature in your instrument cluster? When I got my 2000S it was already enabled, and as a test I disabled and re-enabled it using the durametric. I didn't try to enable it twice though. I don't have the stalk or the button hack so outside temp is all I get.

It has a "!" by the OBC enable

NO I have nothing on mine, My dealer said he could see the 4 stalk arm stepping and switching with his PST....I have a PST connection next week...well worth a 2 hour drive to get to use one of these jewels

Curious what you find out as I have the same issue. Installed 4th stalk a while ago, never enabled it, but soon after put in the pcm2 instead of cdr23. Then my outside temp worked, nothing else with the 4th stalk toggling. Some time later bought a durametric and tried to enable OBC, got the same message of already enabled. Pretty sure the wiring is correct ( pretty simple, I'm an electrician ) Haven't had the time or motivation to tear into it yet and don't wish to pay dealer to hook up to their PST2. I also made sure that the order code is correct which must be done on the 03-04 cars.

Not sure what it means

Be sure that your car is not missing the “Option Code” spec, as this will generate errors when you try to update the car with the tool.

Following your information, I have had the OBC switched on in my 03 Boxster S by my local dealer.As you know on 03 Boxsters the hack to switch on the OBC involves first changing the 'Order type' setting in the DME.I understand the DME is involved with engine control so is it important to set the order type back to it's original state once the OBC has been enabled.I ask this question because since the dealer did the OBC switch on I have noticed a very slight reduction in performance.Did Porsche have good reason to set the order type differently other than to stop OBC switch ons?This could be just my paranoia or a coincidence as the weather has got a lot warmer recently.

The DME has a bearing on OBC function ???

Also found this ;

Tool Pants brought his System Tester to the work on Cars event-- he was able to do what the Dealer claimed would not work and enabled the OBC.

It turns out the Option Code Spec was missing from the computer. Once we entered it, we were able to access and enable the OBC. The software faults on the Instrument Panel & AC (from the radio change) were non-issues.

Now that the OBC is enabled, I'll order the parts.

The DME is the source for all OBC display data and functions, so it has to be correctly coded for everything to work.

The dealers have for some time been under direct orders from Porsche not to activate systems that were not originally ordered on the cars. Porsche did this to stem the aftermarket activations which costs Porsche the revenues they would have gotten if the car was ordered that way, but they also overlooked that non Porsche (PST II, PIWIS) systems (Durametric, Autologic, etc.) can now activate these system in the independent shop markets.

Well that all makes perfect sense, now what should I look for to help rectify this situation ??
