Hi Maggy. The first number you listed, in multiple listings, list it as an Electronic Control Unit (ECU). It was listed with a few details (like) they need your old module and the key, to program. Now given this, I suspect THAT ecu is a skeerm module. Finding those differing descriptions on the first part number, I did not look up the other numbers. If I were you, I would download the various PARTS listings (with actual numbers) in the documents listing (by 180). It seems the term ECU means more than just one module, hence different part numbers. It is quite the quagmire, isn't it? That's why I think you should get those parts listings.
