What do you think? Am i wrong on my solution?

P30ff on the 07 = turbos shot ??. I'd look into upgrading your turbos when your in there change all other stuff that's ither old or needs replacing.

Not a specialist. but I'm thinking you would need a shop to rebuild the turbos and have them balanced etc. a lot more work then just taking the turbos apart and slapping a rebuilt kit on.

I am not a specialist. but i am a specialist for vq35 motors. I am too lazy to make a single turbo kit and plus The bmw is my dd. I don't want to play around too much with this car. I just bought new stock turbos they were cheap. I can't justify spending $5000 on my dd. if it was for my other car np.

[specialist]

Here is a funny thing. I left my car for 3 days and then it start to boost to 15 psi. After just crusing it for a bit the half engine light came on.

p30cf Waste Problems
p3100 limp mode.

Are my turbo really gone?

[maaaaackle]

Wastegates are not sealing properly which is your 30FF code. That would compromise your turbos and the power for sure.

I have hexon rr600s for sale if your interested

Have you tried vacuum test to wastegates and voltage to solenoids?

[specialist]

I will have to try and see. Do you need special tools to do it?

[FamilyManTrackSedan]

little mightypump vacuum pump/bleeder - check amazon. search "bad boost solenoid"

I got 30ff a few years ago, and also had after market inter-cooler. I was worried about all the places to check, started with the easiest which was with the clamps to the inter-cooler. To my surprise, they had loosened over time. I tightened them, 30ff gone, and never came back. We all know some codes unchecked can cause other codes. The point just being, start with the cheapest things you can eliminate as the possible root cause first. I would have looked at vacuum canisters, diverter valves, and every connection on that charge-air track next, once tested good, moved on to waste gates. There is an old post by member sniz that you can search for for a homemade pressure test that helps you be able to listen for leaks if needed. good luck.

Yeah that's a good one. http://www.e90post.com/forums/showthread.php?t=193077

You should start with the vacuum lines all along the top of the engine and near the OFH - they're typical culprits and often you can even see fraying. Just replace the lines you can see. 3.5mm hose at amazon is as cheap as the vacuum pump

more bad news i think one of my injectors went. The code i got was p2e36. injector 6 controller. I thought it was spark plugs so i changed them. no change then i swaped coil packs no change. I put a temp lazer pointer on that injector 6 it was 10 degrees colder then the other ones. So i think i am safe to say to chnage that injector. My luck. I also bought a vaccum pump i put 15 psi in the top of the canisters with the car off it held 15 psi no drop off then i release the presure after 30 sec.

I am now going to home depot to buy a 2.5 pcv cap to make a boost tester. I hope i will catch a break soon

Is your car smoking?

These n54s can trigger 30ffs even with the smallest leak. I wouldn't jump to conclusions right away. Test for leaks. Replace injector and let us know

[specialist]

ok i will check for the leak tomorrow and get a new injector i hope i will be able to find on tomorrow

Also the car is not smoking

#2 appears to include everything you need.

I have #1 and a slide hammer like the one from #2. The only thing you would appear to be missing (with #2) is the specialized cutters to remove the old seal. That's not a big deal.

Get tool tomorrow also getting the program ready for tm. i already have the cable

[specialist]

injectors are in now coding problems

I got my cable loaded the software, launched INPA and the Battery/ing lights are both black but when I try to read codes I get:

ApiCheckJobStatus: Error #95
SYS-0005: OBJECT FILE NOT FOUND
API job error or no such result !

I have reloaded 5 times after then i want to look for boost leaks
