Question about 2007 BMW 335i Coupe
My 335i has a warning come up saying that full power can not be delievered and service asap..essential what happens is if im in a higher gear lower rpm and give it full acceleration a warning picture comes up of a little motor half colored in orange and my turbos quit working and makes very little horsepower until i stop the car and shut it off and restart it...it almost seems like it has a boost leak, bypass valve giving out or a fuel issue...any idea what could be causing this?
Make an obd diagnosis for stored codes , maybe the manifold pressure is fault

SOURCE: Warning light
Usually, the "half full" engine light is when the engine is in reduced power mode. The number one casue of this is a failure of the high pressure fuel pump. This engines fuel system is direct injection and operates at 50 bar (or 725psi). When it fails you only get 5 bar out of the electric low pressure fuel pump. Another symptom that goes along with issue is a longer than normal crank time in the moring. this issuse is not a huge problem the have repaired at the dealer and is covered under the facory warranty

There is an issue with the rear tail lamp bulb holders. BMW knows about this problem and released an updated part. Basically the bulb is not held tight enough, and occasinally loses contact with the holder. Your car should still be under warranty and any local BMW dealer should have the parts in stock.

you have good fuel pressue but do you have enough volume? when was the last time the fuel filter was replaced? and remember this if you replaced the injectors did you replace as a set? oem injectors have a 1 to 2 % veriation aftermarket can have 45% veriation so always replace as a set and get a good set. or you can have driveability problems. but do the fuel filter first and it is a service item which should be changed and this sounds like a fuel filter issue. if this fails to fix it first you can have a shop test the fuel pump with a scope to check the wave pattern and check both press and vol. second on a scanner you can look at live data and check the mass air , tps , o2's the o2's should be going above 500 and below 500 switching from rich to lean , the tps check % on live data they are 0 to 100% , these items also can be checked by a volt meter for resistance a shop would know the values of each. start with the fuel filter then rule out each sensor. proccess of elimination if you do it your self google all info and diagrams you can and take your time rule out each one you will find the problem . one other thing to do is when the engine is cold start it up and spray the intake with brake cleaner listen for changes in rpm to rule out any leak from intake otr vacuum lines ect. this is a always passed over thing .

Your oil is a little low, and the timing may be off a bit but if it smooths out after warm it is probably ljust

Chech the solenoid that operates the turbo, its located beside the EGR solenoid on the bulkhead, I had one where the vacuum pipe was blocked where it connects to the brake vacuum pipe.
