So I've got my project car back together, and it's telling me "check control" "see owner's manual" which tells me bring car to dealer. I've finally figured out "check control" means "check control module".

What is this thing, and what does it do? It's got a part # of 61.34-1388613 and 601-0700-001 on it. It says "Nicht werfen" and it's made by united technologies automotive.

Anyone have any idea at all?
