2006 several issues?
 

Hi.. been a long time since I was on this board. Got my daughter's 2006 X5 with sport suspension back and it had several issues. Did the search but nothing conclusive as it seems these are not straight forward issues ( intermittent). A little background. While I was working on it the drivers window began to slow down. Replaced the regulator (used the URO with the upgraded rollers) Replaced the valve cover with an aluminum one to correct a nasty oil leak. Worked great ( e-bay item for the M54 ). Next was chasing a coolant leak... so hard to find but we narrowed it down to the thermostat housing.. replaced that too and, now no coolant leak. But 2 items came up. When I first start it everything is fine... after about 20 minute of highway driving the check coolant level and the 4x4 light come on..( trying to remember what the display says about that.. think it's 4x4 inoperative) I don't hear a sound when I turn the vehicle off so I don't think it's the 4x4 actuator or gear? Park it and when I restart it.. nothing.. everything is fine....h until I drive about 20 minute and again I get those warnings on the display??? Anyone know what might be causing this?

You need to pull codes. What scanner are you using?

I have a very generic code reader.. nothing very sophisticated and BMW specific.
The steering wheel is off by about 3 degrees to the right. I have it at the shop to get an alignment ( needs it anyway)... trying to rule out the steering angle sensor...Thanks,

OK often time there is no further post when a solution is found. To help, here's the solution to the 4x4 light in my case. Apparently, it was the steering angle sensor. Since the steering wheel was cocked about 3 degrees to the right , a front end alignment and straightening the steering wheel back to center resolved it. No light now.
Still chasing the intermittent "check coolant level" message.. thinking it's a bad sensor on the expansion tank..

What caused the wheel to be off so far and yes you can’t be steering all the time and have the dsc happy.

That it wasn’t immediate is trad strange part to me.

People report on occasion the magnet float will get stuck and cause your symptom. You can unplug the sensor and see if the error light goes off I don’t remember if it’s normally closed or normally open switch.

If the switch/tank is bad just unplug and short the contacts off needed and monitor manually rather than bother switching the tank.

My 2001s didn’t have the sensor. My more coolant warning was the cabin heat stopped working.

Bad coolant (magnetic) switch is often due to a cheap aftermarket expansion tank.
Is that the case here?

Use only BNW reservoir and sensor.
I assumed you checked coolant level?

For 4x4 light...Check tire P.

PS: Win Regulator, I use VDO brand.

Daughter lent the vehicle to someone..... contacted a curb...LOL

Not sure.... I don't remember how long ago it was replaced.. I have a new coolant level sensor and will switch it out... Funny thing is it's very intermittent.. since the 4x4 light could have been caused by low voltage from the alternator and they came on together...thought it might be a low voltage situation triggering the message...Thanks,

A Creator C310 works great on X5s. I kept one in the glove box. I gave it to my sister after she bought an X1. A FoxWell Pro is my go to tool now.

OK, new issue... seems like it's never ending. Began to hear a strange whine that followed engine speed.. ended up being the clutch fan leaking a gray sticky fluid out of it... New one ordered. Keep getting the intermittent "Coolant Level" message.. but now.... wait for it... the coolant temperature sensor "O" ring is leaking just slightly... so I have one of those on the way... Sheeze!!!

Thank you....

Foxwell NT-510 or the bigger, fancier NT-730(?)

Not all foxwell models are able to talk to all the older modules, etc.

710 or 510. Don’t know what 730 is. 710 is what I use now. Best because built in WiFi for update and works with new cars.

Coolant sensor o-ring leak can be stopped with a couple wraps of Teflon[emoji769] tape

Search forum for "cooling overhaul" and use only quality parts before you regret...

I just did that on my n55 motor and don't regret at all (even though it was something like 13 coolant lines and 4 power steering lines: (one of which was rusted maybe 1/2 way though the tube).

Some engines you can find a pretty complete kit. Mine: nope, nada.

I think it took 6-7 orders from 4-5 sources. Painful but worth it.

Figured as much but since I'm in there for the coolant level sensor, fan clutch ,etc.....

OK, replaced the fan clutch and the fan.. ( Good grief, I accidentally dropped the original cracking one of the blades). Replaced the coolant temp "O" ring. Replaced the coolant level sensor.. the one that came out had a black tube shroud around it, that was brittle as hell and disintegrated in my hand. It looked completely intact so I don't think any of it is floating around the coolant passages, hopefully? No leaks so far..finger's crossed.

Coolant level sensor as mentioned by other posters, is not immersed in the coolant. Hall sensor, so it reads off the ball float in the resrvoir. So no worries it goes into the coolant.

I'd assess that fan, dont want it breaking apart and taking out the rad or drive belt system.

I read that wrong also like he used the broken fan. Second read though i caught that he says he replaced the clutch and the fan.

I am thinking the issue is with the float...when I take the cap off it doesn't always rise to the top? That might be what is causing the false check coolant level message. Interesting, I drove 25 miles last night and... no coolant message???

I replaced the fan.

Thanks,
