My Ride: 2003 330i
Changing Thermostat

I'm getting 197B code Controlled Map Thermostat on my 03 330i. I don't seem to have any leaks in the coolant system so I think the Thermostat has gone south. There aren't many posts on changing this out on e46 but I found the video I've linked to below which seems pretty straight forward.

I'm unsure though if I need to drain the coolant from the system or if I can swap out without that step. Any advice or tips if you have done this before would be great. Also is there anything else I should do while in there? (Expansion tank and most hoses are less than a year old)

I changed mine using the above forum, hardest part was getting the fan off. Try nappa I got my T-stat from them for $55, make sure you get the one with the housing its one piece.

This turned out really well and was much easier than I was expecting it to be. The hammer 1 1/4 inch wrench to get the fan off worked like a charm. I did have some concern on the color of the coolant that I had sitting in the thermostat when I removed it. It was a brownish color instead of blue. The radiator was flushed once before when I did the expansion tank so I'm wondering if this is something to be concerned about or not. The car seems to be running running fine and I'm not getting any warnings or codes now. Any thoughts?

Also updating the tags in the post. I noticed several people have had trouble like I did finding the full DIY with pics so hopefully this gives another option.
