What did you do to / for your E53 today??

The weight isn't the problem.
I found the URO metal pulley is not totally concentric so I took it off and put on a new plastic one. Make sure the fan and clutch are in good shape.

Had to do a complete reset/reboot of my stereo. Had a Royal convoy pass me on the inside shoulder breakdown lane running his jammer and it shut all my shit down including my BT OBD2. Not sure what they're running now but it's meaner than the old Acorn, Duke, Red/Green systems.

Did an oil change yesterday at about 5k since the last one. A bit longer than I normally let it go, but I didn’t have time before driving the X to Kansas recently. I’m sending a sample from every other change to Blackstone for an analysis. The motor seems to be aging well (about 25k on it now) so it’s mostly just curiosity. 8+ quarts of 5w 30 full synthetic. I also changed the rear diff oil and put a new gas cap on the car. The tether on the old one snapped and I was going to live with it, until I dropped the cap a few too many times when fueling in a hurry.

The Quaife has been in for roughly 15k, and this is its first oil change after I did a break in service at around 1k on it. Definitely some metal mud on the magnetic plug I use in the diff. All diffs make some metal, but I’m starting to suspect that I either screwed up the output bearing pre-load, or the pin/ring gear adjustment, or the pinion bearing is slowly going bad. That is the only one I didn’t change when I built the eBay diff because I didn’t have the right tools to do a good job, and the pre-load was spot on when I tested it.

Of course it could be the Quaife too, which is essentially a very dense collection of gears. But I suspect my handiwork long before I’d suspect the quaif. Regardless, I only get a very, very slight hum in cold weather, at low speed. Which could be any number of things I guess. Definitely coming from the back of the car tho and only from a dead stop to maybe 25 mph, in cold wx when the car is cold.

A “keep an eye on it” issue.

Scrapped 1/2" of ice this morning. I had to remove enough to free the wipers. Heat and gluteus maximus warmer at full power. Do seat warmers turn off automatically from full power? Mine turned off twice while waiting for heat. No problem driving to work. Even tried to spin all four wheels a few times. No such luck. Xdrive works great. It's rare I get to drive in snow/ice. I'll enjoy the drive while the roads are empty.

On the e70 the seat heat isn't on a timer. I do need to get some cardboard in front of my radiator.

It took bmw a few years to figure out to put in shutters. Wife's 2015 F10 has them and you can get engine heat ins reasonable time on auto.

On mine no heat for 20 min. unless i turn off the heater.

With the right tires the e53 is crazy in snow/ice! I've driven through 15"? Of fresh snow plowing off the top 1/3. I was careful to never stop moving. I've also driven down into a ditch in 6" if wet heavy snow to rescue a grand am that took a turn too fast.

Another time on polished to ice packed snow, pulled a car out sideways from the curb. They were just making polished ice attempting to un-parallel park

My coolant system is set up for hot summers. Trying to warm up at idle does not work. The X5 needs to be moving. It was at half way between blue and mid gauge after 15 minutes. Once I was moving, within 1 mile, it was up to temp. I'll set the seat warmer to mid range this afternoon. I'll see if it turns off. The low range does not turn it off.

No the seat heater should not turn off, so that could be a sign of trouble, maybe a short in the pad starting to get rubbed in from the hog rings in the seat. A drop in voltage could cause them to use extra current and shut down so if your battery was low or charging system not up to the task it could cause that. If it keeps happening maybe turn off the lights and/or turn down the heater fan to see if that helps. Then start a thread
What does "cooling system set up for summers" mean??

I think if you turn off the dsc you can have some fun in the snow

[X5chemist]

Hey, didn't think of turning off DSC! Thanks!

80stech,
"hot weather setup" basically a good mechanical clutch, good water pump, and good thermostat. The thermostat wide open, temps run at 194F (90C) while moving (hot summer temps).

Fog lights, headlights, defrost (full fan speed), door/rear hatch defrost on, and full seat heater turned on at idle is not good! It's probably why the seat heater turned off. Next time, I'll set the seat to the lowest setting. Turn off the lights while defrosting too. I did fully charge the battery two days before the current storm. I wanted a full charge since I knew I had to start up today.

The driver's seat heater in mine started turning itself off this winter. It's always had a hot spot but never shut itself off before. I can get it to stay on if I hike my ass up off the seat and turn it back on. Usually it will stay on after that. The seat back heater doesn't work, never did. I still want to swap the seat cushions with the right side, if possible.

I'm mad that my E53 currently disabled because I'd sure love to be outside playing in the snow with it. I can't drive my F30 in this, Michelin PS4s are garbage in snow and it's RWD only. Fortunately I don't need to go anywhere today.
