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

I am doing a full suspension (hopefully at the same time) as I will have 5 full days along with the possibility of 2 additional days to do everything. Shop space is available for rent then,so....

I'll try to keep progress posted by things are a little hectic at the moment.

The pairing has nothing to do with the fob being powered. You could leave the battery out for days and not lose the pairing..

Right Front caliper has been ordered wouldnt retract

I hope this was the source of the 57-62mph vibration but I doubt it.
Front bearings and CVs are only about 15K miles old, Driveshaft/mid bearing new not even 6K ago so I am guessing its rear wheel bearings?

Had to pull the Z4 out of winter storage a few weeks earlier than I wanted

Helpful info. I had to pair mine more than once when they were acting flaky but prob just switch closing not getting through

I just replaced a rear wheel bearing...but didn't have any vibrations, or at least none more than usual. I would think if one of your WB's is bad enough to cause a vibration, you would likely hear it as well. As I did.

Stuck caliper can for sure cause shimmy if the rotor is not perfectly square. It can also cut a rotor in half. My son and nephew both had this happen last year.

Do you have a shimmy thread going? If not, start one so we can track it down.

There's a simple test to find loose suspension as culprit:

1) when going about 50 mph 80kmh, gently slow down like 5mph with constant brake pressure. If you get a shimmy from this over 90% chance it's from the sideways control arms behind the front axle.

2) drive about 60-65 mph on the center of a highway (on the center lines of two-lane or center of three lane highway). (the point is to be on the top of the crown). Now holding the steering with thumb and one finger, ever so gently steer back and forth past center. You're testing for if the wheels will wobble as they flip from being held left to right and vice versa.

The only time the sideways control arms not the cause from those two it was the steering rack.

Ball joint and tension strut do not usually cause a shimmy.

You can get a shimmy from alignment having too little toe in but that will cause tramlining or wandering before shimmy.

Checked why the X5 was dinging "check license plate". A wire soldered into a circuit board broke. I may try to solder it back. Or order another LED replacement.

Completed fuel testing...

91 Gasoline = drivable (emergency use when poor)

91 Benzene = somewhat better (emergency use)

95 Gasoline = Good (average use)

95 Benzene = really good (normally used)

100 Benzene = really really noticeable (new normal use)

My altitude is 450m and at 21c-24c air temp is where the Witch really seems young again. Too bad that temp is soooooo infrequent.

100 octane Benzene is $2.95 USD per gallon, but only carried at a few stations. Guess what I'm buying from now on.

its not a shimmy, it really really feels/sounds like the growling a wheel bearing race makes when its worn out, and looks like someone took a grinder to it. none of the 4 are loose yet either.

Once I get the caliper on when it warms up(Detroit) I will dig into it. unless it was all just the stuck caliper and it goes away(I can hope but not expecting that)

Bought an emissions smoker to help a friend pass emissions on a '19 Altima. He paid for half of tool costs. I paid the other half. I get to keep the tool. We found the P0170 code cause in 5 minutes. A shop paid to smoke it, found only one issue.

Next, test the X5 emission hoses! Any bets on how many vacuum leaks are found? No codes on mine since doing a coolant refresh and replacing the intake gasket. I replaced anything I could find so I would not remove the intake again. CCV, starter, heat sensor, coolant pipes, filter housing gasket, intake elbow, and small hoses replaced. Suspected vacuum leak locations: upper intake CCV hoses, DISA, and oil cap.
