Question about BMW Cars & Trucks

My 4 cylinder 318i e46 bmw starts ok but as soon as it reaches idle rpm it shuts down. the only way to get it to run is to rev the engine to 3,000 to 4,000 a couple of times and then it seems to settl

Vehicle has been to a european car mechanic who replaced all seals except rear main. before it went it used to "hunt" when it started and would settle to smooth running soon after. when the vehicle came back the above symptems had developed. the mechanic had tried to address the problem to no avail and so sent it to a auto tech person. expensive but useless! i was told to clean the idle control valve by a ferrari mechanic. i have cleaned what i think this is (beside the dipstick after the plastic cover is taken off. still no change

The Ferrari Mechanic was correct, but you have not yet found the valve. The idle control valve is a small air passageway that bypasses the main throttle plate. You did not say what year of vehicle, but I am assuming it has Fuel Injection since the idle control valve was mentioned. Remove the Throttle body and clean it and all the little air passages in it. Then try. The throttle body is the apparatus between the large rubber air hose and the intake manifold.

A couple of possibilities - first I'd check/replace fuel filter. Then clean MAF (Mass Air Flow) sensor and if those don't cure issue then it's TPS (Throttle Positioning Sensor) replacement time. Check w/BavAuto or Pelican Parts online - both good sources for info & parts

SOURCE: I have a 2000 E46 BMW 318i. The trans light is on

Steptronic is a option and not all BMW has it. If this manual gate fails,the steptronic shift will not occur.If the switch up switch fails then there will be no up shift response. If the switch down switch fails there will be no down shift response. This device is located to the center left side of shifter. I dont think you have a transmission problem why would I say that because it stall and you had to rev it up till it clears okay there is something that failed and resemble a transmission failure. Okay I found it here is the definate problem cars used to have EGR when they failed it stall and rough Idle the vehicles your is classic you have a EXHAUST CAM CNTRL SOL(VANOS) failure. why is it failing across the land Motor oil type is of wrong use. once the vanos plugs you get a rough stalling idle the fix well a engine oil flush chemical prior to oil change may work. Or it has to come out and clean the screens itself . This device relies on oil temerature sensor if temperature of oil goes above 212 F ecm deactivates solenoid control. by the way you have 2 vanos one for intake and the other for exhaust.

Idles at 3000 rpm


Your problem seems to be the "Idle control unit" It controls the idle control valve. The box is sometimes green or black and is located in the glove box ceiling next to the ECU. It's approx 4" x 6"in size.

Idle problem


Try to disconnect the Air Flow Meter. It is the first plug just before the air filter/air intake box. If this improves your situation you will need to source a new or aftermarket Air Flow Meter.
