Codes are as follows P2DED | P30FC | P30FF

It always throws the "engine malfunction" light after 6-10 seconds of hard acceleration. If you restart the car, everything seems fine.

2DED Power management: quiescent current
violation

30FC Exhaust fume turbocharger, Density - Turbocharger, boost pressure too low

30FF:
30FF Exhaust fume turbocharger low side

I think its prolly hardware and not tune related

[E90SoFlo]

The light comes on around 6-8 seconds in.

Check your vacuum lines to see if there're brittle or cracked.

I am very confused. I have left my AP connected to my car the past two weeks. From what I can remember, it always shut off with the car. Last night it did not shut off and it stayed on the entire time. I now have this P2DED code. Is it true that the AP cannot clear this code? If so, is there a way to implement a code clear for this in the future? Thanks.

I'm surprised that your AP shut off with the car, mine never does.

Mine does not shut off, its just goes into a "cannot find ecu screen"


Can someone post a diagram of the vacuum line so I can check it. (going to go search now)

I would take a close look at the lines in that last picture. Take off the engine cover and really inspect them, those are the ones that are usually at fault. They do look a little frayed and might just be your culprit...those are the ones that usually go.

GREAT PICS by the way, very clear and detailed.

[Brey335i]

A BT tool or the dealer or your independent BMW mechanic should be able to clear that code for you.

I would retighten all your connections in your engine bay. Check these connections:

From turbos into Intercooler piping, from Intercooler piping into Intercooler, from Intercooler into charge pipe piping, and the charge pipe piping all the way to the throttle body. Also check diverter valves.

If everything seems perfectly tight then you need to replace your vacuum hoses one at a time, beginning with the areas prone to breaking.

I can't get these fraid lines off, any tips
might just cut them off

You need to use a scalpel and cut them off. Just make a longitudinal cut and they will come off.

If you try to pull you will break the nipples (TWSS).

yeah i didn't want to break the tips, i did manage to pop the corner out and its being a bitch to put back in

[E90SoFlo]

Replaced the vacuum hoses, wish me luck.

Let us know how it works out.

[E90SoFlo]

Tested the car, the code on the car is "boost leak in PRESSURE TUBE" what is a pressure tube?

Still throwing all three codes. =/

[bimmertt]

i'd check the chargepipe/dvs. if those are good, i'd check all the piping to and from the intercooler.

Edit: why dont you uninstall the cobb and see if it still limps?

[E90SoFlo]

I will uninstall it today and see what happens.

[E90SoFlo]

I uninstalled it today, and did multiple test up to around 140 and NO CODE. at all.

WHAT IS GOING ON

Same thing happened to me...weird
