Eagerily looking at purchasing a 2010 750Li with about 60k miles on the clock. Long wheel base 7 has been a dream
However, an issue which I suspect could be a major deciding factor that I noticed.
Inspected the car when the engine was cold and immediately on start up there an error message appeared " Engine Malfunction Notification, Engine Overheated ... To Drive Moderately, and if this message pops up again to have BMW Service look at it." Or something similar. Then I noticed the A/C was blowing warm air even when set to the coolest setting.
The error message disappeared after about a few minutes and even going into vehicle status did not reveal anything.
I allowed the engine to run for about 15 mins and no issues or hesitations. At this time could not check the coolant tank as the engine had already reached operating temp.
During the 15 mins or so the engine ran smoothly, no odd noises etc. One thing I did notice though was white smoke from the exhaust upon giving it a little gas which could be condensation, I know for a fact this car has not been driven for a month or so I could be a possibility.
What do you guys think? Could it be a major issue such as allowing the l engine to overheat requiring a rebuild or some other minor issue which upon searching could be a stuck thermostat or early signs of a water pump failure?
Not sure at this stage, may go for another visit and check the coolant reservoir.
