Swapping out the DME with a temporary replacement...

Recommended Posts


I wanted to try a replacement DME in my Boxter 1997 2.5 5sp manual (RoW - UK version)

Dont want to go into why in this thread... I just want to know what I need to do to accomplish this for a quick test I wanted to do.

So apart from the DME unit itself, what other control boxes from the donor vehicle do I need to bring over for it all to work, and where abouts in the vehicle are the particular units located?

I dont want to have to bother with re-programming the donor DME with immobilisor codes etc, I just want to try a different DME, and can bring over the other control boxes as needed for it all to work with no programming...

So what do I need to make a working system?

You need from the donor car, DME - behind the trim in the rear trunk, the alarm control box - under the left seat ( LHD cars ) and the key fobs - remote control. The donor car must have the same transmission as yours, tiptronic or manual.

OK thanks - that confirms it.

1) DME

2) Alarm unit

3) Key heads (with the immobilidsor pill) and key remote controls

Presumably, if I was to install the donor DME and alarm unit in to my car, and in the end decided to keep them installed permanent, I could get an OPC to reflash this donor DME with my correct VIN and immobilizor codes, and I would then use my original key fob / remote control ? Do I need to know details of the original car the DME came from, in order to re-flash it?
