What is/was broken on your E53 today?

If the rear sensor not also tripped you can reset.
I could use a plate from my bearing press and a single lug bolt

That should work very well, better in fact! I had to use 2 since one cap could not support the weight of the rotor against the hub.

Rears are definitely tripped. These rotors are in rough shape, and the pads are virtually non existent in all 4 corners.

I WILL buy an axle puller before I do another one.

Well let me rephrase that. I will buy an axle puller that fits. I bought a front wheel drive car axle puller from autozone but it was way to small to fit the bmw's cv axles.

I will look into an axle puller or make one before I do the left axle again. The right side is easy to remove as there is an access hole in the aluminum plate where you can put in the likes of small crowbar or large screwdriver then hit with a hammer to knock it out it pops right out. The left side there is no way to get behind it.

I think I could use a gear puller on the left side axle I wish I'd have thought of that yesterday

The drivers side is the one that was a pain. The passenger wasn't "easy" but I could at least pry on it from below.

That's why I bought the cv axle puller thing after doing the passenger side. But it was to small for the bmw's axles. There has got to be a "bmw" tool for it.

Hey guys, so what broke on my x5 today, also fixed itself.. Which is a bit concerning! Basically the car wouldn't start. Turn key, everything lights up as normal, turn to start, and nothing at all. On off on off on off etc, nothing. Locked car then unlocked, and car started like normal. Google hasn't been helping me with a solution, other than it might be the key. Spare key wouldn't start car either though (although the spare key battery is flat)

So at a bit of a loss what to do! Grrrr!

Strange no starts like that usually are the sign of a failing ignition switch. If it is it will happen again and again with it taking more and more effort to finally get it to crank.

After changing the front rotors and pads I'm now getting the "trifecta" of lights. Brake, abs, yellow one in the middle.

Not sure if me messing around the hubs disturbed one of the sensors. Or possibly from pushing the caliper pistons back?

Light came on immediately after... Hasn't gone away. These same lights came on after cleaning my driver door harness, but went away within a minute.

PDC works when it's warm outside, but not when it's cold. lol.
Front left throws a code. I have a replacement but am waiting for my RealOEM.com - Part Search to turn up

The abs sensors are sensitive to not being in the correct position.

I have one the the retaining bolts for the abs sensor that broke off and it's only held by friction. It would occasionally wiggle out just a mm or so and trips the trifecta.

The abs sensor is not close to the brake caliper but if you grabbed in the wrong place you could have damaged the wiring which would take replacing the sensor to repair. I don't know how to test eg with Ω meter etc. You could remove them and clean and replace them.

Before I figured out a solution to snug up my loose sensor I had to push it back in 3/4 times. After which it would reset the lights usually within a block of driving. If it didn't reset then some problem still exists. The same condition will happen from a low voltage issue from the alternator so enable the hidden menu in the odometer and set to voltage and verify the voltage stays above 13 even at idle. If the voltage drops low enough the DSC ABS will be disabled

Thanks so much for taking the time to reply! My googling didn't show up anything about ignition switches, but after putting it in, it seems a common problem, and an easy/cheap part to replace, so have ordered a new one, fingers crossed!
