Ski Trip upcoming - Maintenance needed?

So our 35i XDrive reached 125k miles. It is now running well after a couple weeks of work chasing water and oil leaks. I am back into the “I like this car” mood.

Our annual ski trip is coming up and with 1000 miles across Kansas and Colorado each way, I am certain the X5 is the best choice in my fleet. However, I want to make sure I am not missing anything that needs done right now.

In the last 12 months (8000 miles) I did the following:
New Valve cover (PCV failure) and seal
New Oil Cooler & Oil filter housing gaskets
New coils and plugs
New HPFP
New drive belt, tensioner and idler pulleys
Oil Change
Differential and T-Case oil change
Transmission oil change
Rear Brake Pads

I am planning on a full replacement of the coolant, and to do the annual oil change before we go, but wonder what other stuff I may need to take a look into?

Thoughts?

For in the mountains; check the status of the front brakes and brake fluid, and your winter tyres. 4mm thread is the minimum for good snow performance.

If you drain and replace the coolant, also replace the coolant temperature sensor. This is the sensor that relays engine temperature to the ecu so that it can alter the air:fuel ratio.

Where is said sensor? And why replace?

I took it on a quick and fast 200 mile run two weeks ago and monitored the live temp thru the hidden menu. Hovers between 93 to 102 celsius. Peak was 105, lowest while running 89.

AAA member? With a 200 mile plan? Peruse bmw.org for shops along the way.

If you do that, it'll be fine.....

Good advice here. AAA yes. Shops between Arkansas and Denver... not many. Is there a place where I can look those up? BMW.org not pulling up

Location: you appear to be lucky with the N55 - it is located at the very front of the engine in the head (the same unit for the diesel requires intake manifold removal). If you check NewTIS under Repair Manuals and Technical Data, then drill down to Fuel preparation and Control, you should find more specific instructions.

Why? This sensor helps the ECU know true engine operating temperature. These generally fail slowly over time (like my brain?) and report lower than actual operating temperature. This causes richer running, less power and response, and puts a higher load on the emissions system. When it passes a certain threshold value there will be a code, but engine operating parameters are compromised significantly at that point.

My story: my wife had a 2001 Jetta with the 2.0 that we drove until about 175k miles before selling. Around 100-120k miles we could not get better than about 24.5mpg on the highway (cruising around 80-85mph) and power seemed sluggish (or, perhaps more sluggish than normal for the old “2. slow”). I replaced all ignition components, checked the air filter...no improvement. Finally we got the CEL for this coolant temperature sensor. I replaced it. All of a sudden, power and response were restored and mileage went back to 28.5mpg at the same speeds and on the same trips as before. I have had similar results across different cars throughout the years. These days, around 100k miles as I am replacing the majority of wear and tear items and replacing engine coolant I simply include this sensor in my work.

If you notice any difference after this sensor’s replacement, please report back. You have done everything else you need to do and it is always interesting to hear if this one, inexpensive sensor makes a notable difference for this engine.

Same here. Ours is a pleasure to drive when it is in good working order. Really enjoyable.

If you drain the coolant, consider replacing the mickey mouse ears hose that comes from the thermostat to right under the oil cooler. That hose is a known failure point.

I drove my 2006 530xi from East Coast to Denver for Thanksgiving on I-70. We had an unscheduled night in Hays, Kansas when they closed I-70 during the storm that Tuesday. The next morning the highway was open, but pretty dicey. Saw a lot of cars driving too fast with a half dozen off the road as a result. Car was fine there and back.
