Welcome to the site and congrats on picking up your E53.

For the future, please place the type of vehicle you have in your sig, such as I have. It makes it easier to identify what we are working with when trying to help you.

So how many miles are on her? As for lighting, I will let one of the experts chime in on that, but you said it wasn't important. As far as maintenance, do you know how many owners it had? What work was done to it in it's history? Many will probably say, depending on mileage and age to do a full cooling system overhaul. Water pump, rad, coolant res, hoses, etc.

As far as software, do a search on this forum and there are plenty of articles pertaining to your question about software and diag equipment.

Oh, pictures... Pictures would help. We always like to see some E53 porn. Haha tools luck with her and I hope we can all help you in the future.
