the p1619 code is a bmw specific code that reads out as this:

P1619MAP Cooling Control Circuit Signal Low
on the e39, this indicates a problem with the cars thermostat. on your car the thermostat has an electrical connection that is connected to the computer to change its operating characteristics. Usually the problem is corrected by replacing the thermostat and that is what i'd try first. if that doesn't work you then you've probably got a problem with the wiring but that is a much rarer condition. i'd try a new thermostat first!

 

hope this helps.
