The '97 DME is a weird situation. Unlike the 98-99 5.2.2 DME, it is not reprogrammable, as Porsche didn't record any immobilizer or programming codes for these cars. Thus if either the immob. or the dme need replacement on a '97 car, they must both be replaced.

That said, the DME can be replaced with any other 5.2.2 DME from a '98-99 986 or 996 and simply reprogrammed with the correct maps if necessary (ie you buy a 996 5.2.2 DME instead of a Boxster one). Your best bet would probably be to obtain a matching pair from a wrecker as the price of the 5.2.2 DME new from Porsche has gone through the roof. If you buy a used DME separately the codes can be obtained to reprogram it to a non matching immob. (ie if you buy a new immob from Porsche) based upon the VIN number but obtaining the codes can range from easy to impossible depending on the situation.
