Hey guys/gals I have a 2005 Cooper S with the Aisin, it's only got 30k original miles and I've got a check engine light, as well as a few other lights popping. The scanner says something about the transmission causing the problem. I've been researching for a while and I see the solenoids seem to be the most common culprit, however, the symptoms don't match at all, mostly because I have NO symptoms. The car runs and shifts smooth as butter, as it should considering the low mileage, but I still can get the code to stop coming back.. Any ideas? My guess is a bad sensor, but I really have no idea. At 30k it seems to me nothing should be bad.. But it's spent the majority of it's life sitting there looking pretty, so who knows... I was assuming clearing the codes and just driving it more regularly would solve the issue, but it hasn't helped. I'm really at a loss here.

I should add, if I clear the codes and keep the car on, I can drive it all day without the lights coming back on. But if I turn it off and on again, there they are.. This is how I got it to pass inspection actually. The mini mechanic even believed the problem was from sitting and would likely go away by simply driving it. I surely don't know, so maybe someone here does!

Any help would be greatly appreciated. Thanks in advance! I'm loving how big and devoted the Mini R53 community is! I'm looking forward to going ***** deep and having a blast! haha
