Just bought my first X5. New challenge to make it run:)

Just went to the pump, fueled all the way and then some! Nothing spilled on the floor (like the previous owner told me would happen to him if he filled all the way). No smell of fuel inside the car, unless I smelled too much fuel today and can't smell it anymore. The top of fuel pump is completely dry.

Thanks for letting me know about the clamps. The previous guy installed the worm type clamp. I didn't like it, as if I tightened it, it would actually squeeze the rubber through the little spaces in the clamp. So I decided to install the second clamp lol. After reading your comment I really loosened the worm clamp. By the way, even without the clamps, taking off that hose was extremely hard!

I will order the ones you recommend!
You're right the end of the hose is damaged and is kinda frayed. I was thinking about cutting it off. There's a bit of slack, but very little. I will cut it when I get the correct clamps. Btw is there any way to extend that hose a bit.

Honestly I don't feel the need for plastic hose clamps as there was very little fuel that spilled, especially compared to how much spilled from the pump.

Thanks for the tip though!
I will need to buy a better pump in any case, cuz the pump that's inside is actually smaller in size than OEM. I compared them because the previous owner gave me the old one he replaced.
The pump he installed is some kind of a no brand toy pump!


Well I guess now I can move on to the rear left tail light and parking sensors

I use a special tool in order to effortlessly remove smaller sized hoses such as this.

You shouldn't extend the hose with anything, but there should be enough slack to cut a bit off the end and reinstall it. I tested this myself in the case where I would have had to do it.

Thanks for the tip!
Ordered the clamps and leslie tool.
With how much I work on my car, gotta have the proper tools!
This "POS car" is coming along nicely ��

good stuff! and good tip about the clamps, easy not to think about. Those pliers look like something I need in my toolbox!

Bought this $15 MAF sensor and somehow it worked lol
No more trans fail error, maf code is gone and no more jerking of the car when stopping or starting to drive
I thought can't go wrong for $15 and can return it with amazon prime
I have no clue how this works cuz I know bmw electronic components are extremely precise

Maybe it's just an empty plastic housing and the car is running sans the MAF control (i.e. off a map). Basically the same as unplugging the old MAF (did you try that?).

[Bmwe5320023.0]

Haha yes I've been driving without maf for the last few days, had a code p0102 and trans fail error, the car would jerk as well.
Someone gave me a smaller maf from another bmw engine and said the sensor is the same and it would work. Just the housing was smaller.
So I pried off the sensor and glued it to my original maf housing.
The car wouldn't run at all, would shut down right away. So I disconnected maf and drove without it.
That's why I can definitely say this $15 maf sensor does work.
And with this maf my rpm at 100kmph went from 3000 to 2000

The car has been driving great since changing the throttle body. I also changed all the fluids and filters so now is a good time to address the wiring issue.

The tail lights are such a mess.

This is the right side.
Black and white wire is cut off, I guess it's no longer needed with the new tail lights. Brown is ground, I opened it for testing.
Black wire is the one that's spliced to bring power to the left tail light.
You can see on the left side how the wire that's been spliced on the right side comes to give power to the left side.

The black wire on left side is cut off and I'm thinking because it probably doesn't have any power.
I tested it with a multimeter and there's nothing, while the same black wire on the right has voltage.
Wherever this black wire is coming from, it lost power somewhere.

Happy to see you are sorting things out. One issue at a time, that's the way to approach it to learn about your X.

I wanna see a picture of this bad boy, lol !
