Babooska, I have ETK on my computer, great system but I caution you that when looking up parts and rattling off a part number to order a part at your local BMW dealer, the dealers number may be different. I have had this happen a couple of times.
The real value of this program is the ability to check out different models and see if the part No. is the same or different for your particular bike as opposed to a mates later model bike. An example is to see if the 94-96 plastic fuel tank is the same for the 96-2000 model. A quick look will tell you that the part No's are different and that the rubbers up front are different. But the seats are the same part No. so for secondhand stuff this program is quite fantastic.
you would have to have access to the CD that you originally loaded the program from, to load what you are missing. I don't know what you are talking about as I don't remember anymore what I loaded as it was about 2 years ago.
Mick.
