My 2018 835M is getting an intermittent Warning and Engine Light but no DTC codes are captured. I have had it into two different dealerships which has been a waste of time and money. Unlike my 825I - the engine fan in my 835M never runs even though it is driven on 20 miles of dirt roads on farm in very hot temperatures. I'm curious if anyone has had any issue with intermittent Warning and Engine lights which come on and off for maybe a couple of seconds. I'm also curious if anyone else has an 835 model and if they have noticed their engine fan not running even when it is very hot. I'm new to this forum even though I have owned some model of a gator for almost 30 years starting off with the 6 X 4 Gator.
