Vpg2002x

I've googled and searched tons of boards and can't find any images that are still hosted for the location of the icv on my 2007 535xi. Anyone give accurate location or provide images for the location would be greatly appreciated.

Above photo shows a M54 engine. I believe a 2007 535 has the N54 engine which is a direct injection, twin turbo, valvetronic engine. As such, I don't think it has a ICV. Idle speed is controlled by the valvetronic stepper motor.

I think that idle issues are usually the result of carbon build up on the intake valves. Since direct injection, no fuel washes the intake valve and hence oil vapor builds "carbon" on the backside of the intake valve and thus restricts air flow during idle (valves barely opening on valvetronic engine). Solution is to walnut (media) blast the intake valves clean. I hear this is a 40k mile interval necessity.

Of course, I could be totally wrong as I do not have nor have ever had a N54B30 engine.
