The Carsoft setup that I have will read codes from all systems, it even reads that I have a few problems with my instrument cluster. It only cost me about $150 from some company in Hong Kong... Something like www.one-stop-factory.com they sell the interface, all you have to do is find the software to make the interface work. Use you favorite file sharing software to do that.

I am guessing that it is just my problem is just tied to the fact that it is wet outside... Electrical components get better continuity when it is wet outside. Mine used to have problems starting when it was dry, but since it started raining very heavily my X has not acted up. This is the longest I have seen the thing go without having any problems. When I bought the car it was winter and it ran fine... Summer came and it had problems starting. It doesn't do it only when the car is warm, mine has had troubles many times starting in the morning where the car has sat for a good 8 hours at least.

Thanks Texmin for the idea, it sounds to me like it may be worth looking into. Even if it doesn't work with our X5s it should work with a lot of other vehicles, which would make it worth the cost down the road somewhere. Sounds like a cool little toy at least!
