  1. On the 530d e39, this summer I suspected the thermostat to do the same not closing fully, the car was longer to warm up but once fully openend, solid 12 o'clock temp gauge, but I was suspicious. I ordered the thermostat with a water pump (plastic turbine, I broke one on my 325tds last year). During fall, the temp was just over the 1/4 mark, except in traffic or in city (and was going really cold during big downhills). Just to wait a week or two, I covered barely a half of the radiator with a piece of cardboard being cautious not to cover the turbo intercooler of course. It worked great, back to solid temps. Then I changed all this stuff, and cleaned the fins because man they were loaded with crap ! Back to almost new now (155k mi)

  2.  @TedwardDrives Aha I bet, technically speaking, if done wisely and correctly the cardboard trick works well during winter (it's just manually resizing the cooling capacity to the winter temps). I also removed the top rad panel to let air escape (don't remember how the e92 is built though, my dealership years are far now 😂)
