SOURCE: 1996 BMW i 328 won't start

hello, check for a damage crank position sensor this sensor sends the singnal to the dme (digital motor electronics ) to inject fuel and pulse the ing coils and will also start the fuel pump when it see a rpm above 500 this is a good tell sing if you crank the engine and the rpm does not jump there is a good chance that the crank posistion sensor is bad / the battery and engine light will be on untill the engine strarts

SOURCE: BMW E46 fault code P2799 - what does it mean

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.

SOURCE: Car starts then immediately idles down and shuts off

i have had the same problem at times. my car would start and then shut off. but i found that i needed oil and check my oil and it was a quater low put in some oil and everything went fine i notices that everytime the oil is low the same thing happens also depending on the position of the car being park meaning that if you are in a down hill position or up hill position i will do the same. so you have to accelarate for 1 minute to have the oil go up. i hope this works
