What is/was broken on your E53 today?

[OrangeFurious]

EEPROM-KI on the cluster, random air ride deflation, groaning in the power steering and what feels like a flat spot in the throttle response. So pretty much the normal quantity of issues, with the symptoms on shuffle.

Is your power steering full? Ever change the fluid? Wife's x5 moaned like crazy when it was cold outside. Fluid was low problem solved when I topped it off.

The gas pedal is almost identical to the old school volume knob of a stereo receiver. I think there are two parallel potentiometers for when one fails. If one fails and has an area of low or high resistance it will act just like you are saying "flat spot". It shouldn't be terribly expensive or difficult. I'm betting you can put an ohm meter on to verify

Check the O ring on the reservoir as well. Mine was groaning as well. Opened it up and it had low fluid. also had a fine mist of fluid all over the housing. checked the o ring - hard as a rock. New o ring, no leak and no more groaning.

Same exact experience for me. Weird how the mist just somehow saturates the area with a film and you can't find a point source for it. But yes, simple replacement of the reservoir cap o-ring fixed it for me too.

BTW - tip for those cases where you've got a non-sealing seal and can't immediately replace with new ... sometimes one side of the gasket is harder than the other, so just flipping it over and reinstalling it will improve or even fix things for a while.

***doing the happy steering wheel stays put dance***

Fixed the automatic steering wheel moving

I posted a thread on it. This one was driving me flat nuts.

That's awesome.

LHF door handle carrier arrived today. Will pull the door apart tomorrow.

And then probably pull the Mrs drivers door apart and replace the window clips that I've been meaning to do for a year.

I have two doors that don't behave properly: drivers door will not reliably lock or unlock from the key fob, the left rear door will lock but not unlock from central lock but will lock. Anybody have experience with either of these. I just need to know if I need to replace parts or just clean and lubricate.

I know the doors on these cars suck, and it makes sense to first suspect a problem in there. But I've had similar intermittent remote issues on my '01, and it has ended up being weak batteries in the diamond keys. Our keys are old by now, and the rechargeable batteries in there are not what they used to be.

It charges while in the ignition with the key ON, but with an old key and a lot of short trips (using the remote but not enough drive time to recharge it), we would eventually get flaky performance from the remotes.

Solution (I've done this twice now, with spectacular results):
Park in driveway, hooked up to battery charger at the convenient ports in the engine bay.
Key in ignition, turned to ON
All other remote keys (we have 4 total) taped in place as close to the first one as possible
Leave it there overnight to charge up

The battery charger is of course to make sure the car battery does not die. Yes a lot of effort to get some charge into those tiny key batteries, but this has worked perfectly for me. Other methods I've read on here, such as using an electric toothbrush inductive charger, have not worked at all.

Other than the few cents of electricity you burn keeping the car powered on overnight, unless your car gets stolen, there's really no downside to trying this first.

And I know it seems to make sense that if the key battery is the issue, then all doors would either open or not, rather than flaky, differing behavior between different doors. But I've learned that these cars are so complex that it's good to always keep a little doubt in mind when debugging.

Last time this happened to me (when my son finally let me know he'd been having issues with the key remote), I methodically went through all keys and all buttons, etc. logging results trying to scientifically isolate the problem. The answer I got was that basically things were flaky, although somewhat repeatable. The recharging solution above fixed them all - going from flaky to rock solid, overnight.

On the first time I did this, things had got so bad that I think I had to reprogram the keys (easy procedure, given on here in a few places).
