I went and watched a video on changing the fuel filter on an E53. WTH were they thinking? There aren't that many bolts holding the dash in.
Its really not that bad, I rarely have to take the whole cover down, only on the super stuck & rusty ones. Its hard to remember exactly without being in front of that shield, but I believe I pull the front bolts & most of the side bolts. Both center driveshaft bearing bolts & then pull the cover down. I use 5-6 long 2 X 4 s to hold it down out of my way. I also have the advantage of a lift so this method may not work for everyone.

I ordered a digital fuel pressure gauge like you put in a dash or a pod that comes with 9 feet of line between the sensor and the gauge. Im going to wire a 12volt cig lighter plug to it when it gets here.

With this I should be able to tap the fuel line for a reading and drive the car and watch the fuel pressure.

I have been meaning to do this for awhile. I had a Bluetooth one years ago but cant find it. But with this rig I can test the problem I am having on the new x5 and a problem one of my pickup trucks is having too so it will be handy to have.

It gets here Thursday so after that I can rule out the pump, pickup screen and filter at least.

Im trying to find an adapter that fits the bmw Schrader valve and will accept the plug on the fuel gauge's sensor. Preferably a 90 degree turn one.

Here is what I bought :

Fuel Pressure Sensor with 1/8 NPT Threads



Anyone want to help me find the plumbing I need to connect his to the fuel rail

Well I may of fixed the no power and rough running problem. I went to napa and bought a bottle of heet water remover and dumped it in the tank. It spit and sputtered a bit when I started it up but seemed to run better. I went for a drive and it did great. I put about 15 miles total on it and never had a problem. Maybe its fixed.

Someone wanted me to post pics of the hole I drilled in the battery compartment under the spare tire to keep water from pooling up.

Here they are.

One pic shows with normal lighting.

The other picture has the compartment dark so you can see the light coming thru from under the car to spot the hole I drilled.

Thanks Crowz!

I might take that on when I do the rear fog light wiring back there.

Why is water getting into the battery compartment?

Could be clogged rear drains. Or a rain storm hard and long enough to over power them. That's what happened to mine. Had torrential rains over the course of a week and it flooded that electronics area. Drains were fine as far as I could tell. I now drill a couple of small holes in there to mitigate any possibilities in the future of a repeat.

Well I still have lean codes but the car runs great after replacing the fuel filter.

So I built a portable fuel pressure rig using a maxtow fuel pressure gauge.

I started out by removing the mechanical fuel pressure gauge from my fuel pressure tester and screwed the sensor for the maxtow gauge in its place.

Next I spliced the cigarette lighter power adapter cable I bought onto the maxtow power leads.
