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 ???

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.
