Cold weather gas leak

[lord4play]

Hello everyone, I have a problem that only happens when the weather is below zero. It's currently -10 and my x5 hates it. Again this only happens below zero at one degree or higher it doesn't leak. Fuel sprays out the side of the injector from the tiny hole on each side near the top. The colder the weather the more that sprays out at -10 it sprays out 2 of the injectors at -20 it spray out 4 of the injectors.
Any idea how to fix it? Will replacing the injectors solve the prolem?
Or should I just start it and wait till it burns?

HOLY SHIIIIII!!!!!! You're gonna create a fireball under the hood pretty soon. Get that fixed RIGHT AWAY!

My guess, fuel injector orings shrinks so bad at low temp. Might want to check the fuel rail as well. But orings is the 1st thing & only thing comes to my mind.

Good luck, and get it fixed NOW!

The M54 injectors are known to do it when it is VERY COLD.

Read the thread by doru in E39 forum. And yes, you need 6 new injectors. Check to see if there is a good-will recall from BMW?

About $125/each injector (PN 13537546245):
2015 Bmw replacement Injector in stock.

PS: Of course ground the car until you fix it!

I think another person also posted a youtube video showing the ? crack in the injector body itself (or where the components are joined together). See the video below. Best is to ask someone to turn key to position II (fuel pump energized), no need to start engine, then look carefully at the injector body: if you see the leak as in the video, you need new injectors:

may not need injectors, just the o-rings which can be bought separately.

If you are getting the leak down from the body joint (which is a problem on older batches of Siemens VDO injectors), it will be very easy to check - pull the rail and prime the rail, then leave a dry rag under the injectors, after about 30 mins you'll be able to see which is leaking as it will leak down - a good injector won't do that at all

It doesn't seem to be the o-ring there is a small hole on each side of the injector. It looks. Like that hole was made into it from the factory. That's where the gas is spraying out. It only does it when the temp is below zero once the temp is above zero it doesn't leak or spray.
I think this is the final straw in nickel and diming me to death. Next weekend I am going to look at a 2010 Cadillac cts with 60k on it. Monthly payments are in my price range.
To bad I JUST put new tires on it they have 45 miles on them.

^Then you need new injectors - the hole in the body is a manufacturing defect

What wheels / tires do you have? I can trade you a set of 19" stock 2005 4.4 rims with decent tread if yours are good looking. Throw you some cash and pay the shipping. We both win and we both know it makes no difference on trade in...

They are the stock 5 spoke there is a scratch on the inside of one of the rim from a brake caliper the tires are 255 55 18 Pirelli scorpion all season plus v rated. I honestly don't think it would be worth it on your end I don't think you really want them.

The X5 is a fine car, each new injector is $95. So roughly $600 for 6 new injectors. The other option is rebuilt injectors.

Did you ask BMW for good-will? Any recall?
