E60 / E61 (2004 - 2010)
BMW 5-Series E60 Sedan was first seen in the Unites States in the fall of 2003 with a 2004 Model Year designation. The E61 wagon followed shortly there after. The E60/E61 5 series is now available as a 528i, 528xi, 535i, 535xi, 550i and a 535xi sports wagon! -- View the E60 Wiki

Likely the sunroof drain hoses.

Any idea what these are and if they should be protected? I found it odd that electronics would be so close below the water drain spout. This is just above the dynamic drive valve block on passenger side wheel well.
I had the same issue with clogged spouts on both sides. Saw the wiring, and I think it was the ABS or brake pad wear sensors. Don't remember but either way, likely not going to be an issue till the cars are much older and possibly suffer from tape and wire sheathing issues. It's not like they're constantly wet, especially out here (though recent weather has been nuts, with another storm on its way tonight).

Do you have a 2nd key to use in start attempt? Might be something that simple.
It is 11yrs old after all.

Not to be an alarmist but most people seem to miss water around the ECU/e-box. Maybe due to the fact that water can get out of the plastic housing were the fan is attached. So my advice would still be to take the box and disconnect the cables to see inside the plugs. Seems to be the only way that find a tell tale of water, unless you want to look at the actual circuit board for water damage.

I had pulled off two connectors from one of the devices in the ECU box and the pins all looked clean without any signs of water in there.

Yesterday I tested the water drainage between the trunk and quarter panel and water was draining out from under the bumper. I could see it running behind the air vent that is there. I actually think the water leaks in through the air vent because I saw a tiny bit of water around it when I opened up the battery compartment the first time a couple weeks ago. I'm still looking for a DIY on how to take out the vents to replace.

I also removed the tail lights and the gasket looked clean and in place without any signs of water. I cleaned up the body where it makes contact and put a thin layer of vaseline to help reseat the gasket. I will do further tests once the car is up and running.

I will test the sunroof drains next. Note, I did not see any tube on either side of the trunk compartment - will check behind rear wheel well next.

Quick update on the thread. I have INPA installed and the cable now. I need to run the DME CAS sync and try to start the car. The voltage in the battery was low again, so getting it recharged now before I try it. I will likely replace it with an AGM battery since it is approaching 4 years old anyways.

I was reading I need to Code and Register the new battery. Does the Carly App handle both coding and registering?

Yes. Carly can do that.

I love the BMW community and it was a big reason why I bought a 5 series again. I want to thank everyone who replied in this thread.

My car finally started. It took a week for me to get INPA working on an old laptop and I was able to perform the EWS CAS sync (in German!) today. I put in a new 95Ah AGM Battery. Registered it with Carly App. The car initially didn't start, but I remembered the note from MysticRob and in Fred's link about the Fob possibly not working. So tried my 2nd FOB and finally started!

Summarizing the issue for future:
I think the Battery was the main issue all along (it was just under 4 years old) and I was able to get a Made in Germany 95Ah AGM battery for a really good price ($125) so I don't mind upgrading that. In hindsight, I should have started there first as I had the same issue in my E39 many years ago. Even then the auto stores all tested my battery fine. I plan to use a Schumacher battery maintainer once a week.

The multiple failed start attempts led to the EWS CAS sync code. I was able to get INPA installed to handle this. Now I have some diagnostics software and the cable. I'll retry getting an English version again. Also got the Carly adapter and app (~$140, but worthwhile investment)

I replaced a fuel pump relay that wasn't necessary ($40). Also replaced the crankshaft sensor ($100) - I don't mind the CPS one too much since it was 10+ years old.

I took care of clearing out most of the potential drain/water leak areas but will be making sure the rear quarter panel and sunroof drains are free and clear since there was some water in the battery area.

Lastly, I noticed the Battery Voltage (measured in Carly) was 13.9-14.1V at idle - is ~14V normal for an AGM battery or too low? Supposedly previous owner had put in a new Bosch alternator recently and forum opinions were mixed on this.

One more update. I checked the sunroof drain holes and they all appear to be draining correctly. Front holes drain in the front door pillars and the rear drain somewhere in the rear wheel well. I still have not been able to locate the hoses in the rear wheel well or behind the fuse box in the trunk. In either case, they appear to drain fine.

A few weeks ago I did find a ton of water in the battery compartment. I still think the Trunk Louver Vent - which is above the battery - is leaking. When I pour water on the rear windshield I can see water flow behind the vent. How does it come off?

Lastly, with all the water problems this car has I'm thinking of installing some water sensor alarms in the battery compartment, spare wheel well, and possibly under carpet on front passenger side. A set of 3 "dumb" alarms is less tan $20 and seems like a worthwhile investment. Haven't seen this mentioned but what do you think? example at Amazon

I bought a six pack of water alarms but the squeaker is not loud enough and of too high a frequency for me to hear.

I looked at your AmaXon link and saw mention of "high frequency" and read the product 'specifications' to NOT see a frequency adjustment.
