Everything went well but only filled up with 2 gallons for my coolant reservoir? Seems a little low to me. Only issue I ran into was the coolant drain plug broke off so I had to ghetto rig a metric 10mm stainless steel screw with a gasket on there and actually functions much better than the crappy OEM part. I ordered it from BMW and should be in next week just to have a backup. I didn't put the undercover back on yet since it's in the 90's by me
gonna drive it without it until the replacement plug comes in.
