ECU means Emission Control Unit. This is the computer and you need the OBDII to read the code. That code itells you where is the problem of your car. Only mechanic has this device. You can get your own too. Its only $65.00. Shop to online more cheaper. It is neccessary to have this device so that you know what you are telling when you go to the mechanic. They can not cheat you You can use this too to reset the computer. So very usefull for the cars. ok.

Check all positive (b+) fuel system electrical components. Injectors, fuel pump, regualtor, etc.

If is for a 3 series compact (318ti most common) then
P2799 is the intake air tem sensor 2
Which would explain the high idleing. Probably a sensor problem (bmw will charge) a competant mechanic should do it easily.
