My new to me X5 is on its way here

[Crowz]

Im charging up the laptop I use for diags now and will see what I can see in a bit. Temp outside is falling fast so it may be tomorrow before I tackle it.

If it can't communicate there might be a fuse to the system or the module itself is dead. Water can get into that tray down there somehow. I don't remember how (it was a monsoon style rainstorm, but could not find manner of ingress), but water killed the air module on my rear axle air 4.4i and was only fixed with a "new" used module from ebay.

It absolutely flooded the spare tire well. After that I drilled a few small holes in key areas and never had any problems after that. Not sure if water ever got back in there, but I took no chances.

Well the "tub" the tire in is dry but the area under that where the battery is may have water in it. Havent removed the spare yet.

Its just to cold for my old bones out there tonight. I will try to do more to it tomorrow when the suns up.

Sorry, force of habit calling it the spare tire well, which is what it would be on most cars. I meant the electronics tub that is under the spare tire. It's an interesting way to conveniently house all the expensive electronics in an area that can turn into a small comfortable pool for said electronics. I seem to remember threads of people losing PDC, Air suspension, and radio functionality after a big storm.

Pretty common and will cause an owner to sell it to the shop. The water in the rear wells usually comes in from clogged sunroof drains.

Ok did the intake boot repair.

Of course I started out with the blood sacrifice right off the bat.

[Crowz]

Also I managed to break a host clamp during the reinstall.

Last but not least this is what I was dealing with

The youtube video below shows the redneck mess they did to the intake boot in more detail.

After all of this it purrs like a kitten now. Super smooth and what I thought was normal intake air flow noise was actually one massive vacuum leak.

What a mess. UGH. Some people. Also was there water in the electronics area in the boot?

[Crowz]

I never got to the air suspension stuff. Took all day on the intake boot. Had a late start waiting on it to get warm enough outside to work on it and then all the problems doing the fix on that didn't leave me time for it.

Maybe tomorrow.
