Strange. When I took mine in for the airbag and fuel recall I was in and out in a few hours.

I have no clue, the where also buzzy with another X5 and was the same amount of work.

I will check ista and see what that they should do.

cleaned up the X5 and tried to fix the sun roof drain. Driver's front drain not draining unfortunately. Other drains drains just fine.

What method/s did you try?

String trimmer line up from below or "canned air" duster? Also on the e53 a common fault is the tube is pinched behind the a pillar. Not sure if that still happens on e70

E70 definitely has a similar, but different problem. The drain hose connects to a molded rubber fitting that is supposed to angle the water down. Apparently at the factory, they installed it and then rotated it to the down position - oblivious to the fact they just put a huge twist in the hose blocking any water from flowing. BMW even issued a service bulletin on it. Kind of a pain to fix the passenger side due to the washer fluid reservoir. I think the driver side is easier.

Apparently when you have a big vacuum hose leak on the turbo side, it must cause rapid use of DEF.

I got my 1000 mile countdown after fixing my vacuum leak, so I put a half gallon of DEF in my passive tank as I usually do. This surprised me, as it had not been long since I had added a half gallon, but... whatever. Oddly, my countdown did not go away over the next few hundred miles of driving which made me suspect I had a problem with the transfer system from the passive to active tank.

I pulled the splash guard on the right side and confirmed I was getting no DEF out of the supply hose. I blew compressed air, I pressurized my passive tank, but nothing. So, I pulled the left side splash guards off (I loathe you, BMW - these covers should not be so time-consuming to remove/install). I pulled the hose off the tank and found I had not blockage either direction.

The only explanation is that.... I was out of DEF in the passive tank despite having added a half gallon just maybe 1000 miles ago PLUS having just added another half gallon. Sure enough, I had to add 2.5 gallons to get enough in the passive tank to overcome my sloping driveway (nose down - pickup is at the very rear of the passive tank).

So, I'd torn everything apart, blown out all the lines,.... only to ultimately discover.... I was out of DEF. Arggghhhhh!!!

AM.

So the way way waaaay more logical solution is to cut the hose and install a splice!

I'm having a problem with water collecting in the cavity directly behind the left rear wheel.

It does not appear to come from the tail light.

I will start a thread when I have time to work on it.

ugh. I was not looking forward to remove the a pillar cover and inspect. I suppose I have to do it at one point. Anytime I have rain, I park the x5 certain to angle water towards to rear drains. 95% of time, it works. Otherwise I do my best to park inside the garage to keep it dry.

I did both method using air compressor and string trimmer. I know on my old E53, the hose was simply disconnected causing water leaks down to LCM. This is the how I got the X5 so cheap lol. It runs beautiful and sold it to my mechanic. I definitely made his day with new car. X5 gets much better MPG compared to his Jeep GC.

You don't need to on the E70. See my post number 6 on this thread: https://www.bimmerfest.com/threads/p...#post-13841555
