Auto up/down feature of windows via key fob

[M5XTu]

I just acquired PA Soft and can code cool features on the E39 now.

What module controls the up/down feature of the windows via key fob?

If I hold the unlock button down, everything opens.

[M5XTu]

Yes. Also, if you hold the lock/arm button, the windows should all go up and sunroof slides closed. But, that feature is disabled for the North American market. It needs to be coded in.

GM controls windows, locks etc. sometimes directly and sometimes as the master controller through other modules, like the seat memory, keyless entry, alarm (those are 2 different systems) etc.

Be aware PASoft is not always perfect with their tickbox coding options. They've been known to make mistakes or have bugs... a worst case would be you brick a module. That said I'm not aware of any particular issues w/ E39 GM or LCM (the modules people are most intrested in hand coding) but the airbag module is particularly prone to 'bricking' so strongly suggest you do NOT try to do something clever with that one like disable passenger seat occupancy sensor or whatever, even if it shows up as a handy dandy tickbox in PASoft.

Thanks for the heads up about the airbag module.

I just didn’t see the tick box for the window up option.

Slight off-topic, but I’ve been meaning to purchase PA Soft for a very long time. Where is the best place to purchase a copy?

In the BMW coding its got some non-obvious name like "convenience open remote" or something (not saying its that it's just something like that...).

I may be confusing models but I think theres individual settings for key and remote (i.e. "convenience open key" means it works in the door locks) and separate settings for the open and close functions... so there might be 4 different variables to switch it all on.

Now again maybe I'm thinking of another car, or maybe PASoft handles that for you so they make it one tickbox... I could open my PASoft and check but... stuff going on... But look for those types of settings and you'll figure it out I'm sure.

Oh of course and PASoft only exposes a few of the configuratble options available so there's also the chance it doesn't support that option but I'm guessing it does since that's one even the dealers are allowed to program (and the dealers aren't generally allowed to tweak jackshiz by the factory compared to what is actually possible inside the modules).

IIRC BMW calls it comfort something, i think it has to do with the purpose is so you can remotely open the windows when it's to cool the interior.

I can't remember which software I used to get mine working I do have Pa soft but I think it took NCS to get it to work. One thing to note with PA soft is to make sure you have the correct version of module selected (on my car some auto select correctly but others don't) and make a back up before you do anything.

One thing I hate about having it enable is I've had a couple of time that while working on a machine while leaning over the sheet metal one of the buttons has got held in long enough to activate the feature(also happens while working under car ). On the plus side it only happens at shops I'm working near and parked near the roll up door but still freaks me out to walk up to the car with windows/sunroof open.

On the other hand it's nice that I can close things up if it starts raining(I almost always leave sunroof in tilt although with the gutter system even if I don't close I haven't had water inside yet) without going outside.

It would be under ZKE coding...and like mentioned...it's called "convenient opening/locking". BMW NA did not enable the "locking (remote control)" feature that is circled in red in pic below.

[M5XTu]

Thanks, Q. Now that you brought up this picture, what is the servotronic feature on the top left?

...what is the servotronic feature on the top left?

Servotronics was a feature offered on some models that boosted assist of the power steering system under low speed conditions...it counter-acts the complaint some owners have of the vehicle feeling "heavy" when trying to park or maneuver at low speeds.

Servotronic:

Effortless agility when parking, light-footed responsiveness and stability at higher speeds: Servotronic adjusts the amount of steering assistance to suit the current speed, enhancing driver comfort by lowering the effort needed to turn the steering wheel.

[M5XTu]

Can this be enabled just by a check mark or must I also have the servo in the steering gear assembly? 2001 540i/6.

You have to have it...it's not just software.

You don't have any specific model info...so we can't tell if you have one of the V8s or one of the I6 models. The e39 V8s imported to the US market wasn't offered servotronics (the e38 7 series did get this option). The Euro V8s did get the option of a steering box w/servotronics...you can see the part nbr info at the link below.

The e39 models with I6 engines...could be optioned with servotronics...and the control was integrated into the basic module.

You can see at the link below...that the e39 V8s (in Europe) had the option of two different steering boxes (item #1) as well as item #5:

{the I6 models w/rack-n-pinion could be optioned with servotronics...see #2 in diagram and part nbr index below}

{#1 in diagram below is the "torque convertor" for I6 models that have servotronics}

The only 2 things to add about Servotronic (ha ha rare event to be able to fill in a gap to a Q7 post) is...

1. "Servotronic" is actually a ZF feature brand for 'variable assist', therefore although people think its a BMW thing, you'll sometimes see it for other cars like Audis or MB etc. as well. They've used it going back to the early/mid-90's or so I believe.

2. E39 M5's DO have Servotronic, but they drive the Servotronic by the DME instead of the GM. So when you retrofit the M5 box to a 540, you have to run the wires, and then turn on the Servotronic in the GM (and the GM has to be a "high" model).

What I don't know is what M62 E53's have. Given the E38/39/53 are all really platform cousins I could see it being either way (either having it like the E38 or not like the E39 540).

[M5XTu]

The ZF steering gear I have is 1095189. Both come as servotronic and non-servotronic. I have seen them on fleabay for the E39/E38 model. I have a buddy who retrofitted his E39. I may be able to learn from him where he installed those 2 wires.

That's a confusing bunch of statements, not sure what you think you know.

Again. For USA steering boxes:

The USA E39 540 never came with a Servotronic box. Not ever. If you see a USA E39 540 steering box it is not Servotronic.
The USA E38 came with Servotronic. If you see an E38 740 steering box, it IS Servotronic.
The USA E39 M5 came with a Servotronic box always (and a different ratio which is why it's a desirable retrofit project, not because of the Servotronic per se).
And again, I am unclear about E53 V8's but I'm too lazy / too don't care to REALOEM the stuff ATM.

There are a number of threads that explain this and the M5-to-540 retrofit procedure and wiring and coding requirements.

[M5XTu]

I am not negating any of your statements at all. I am just simply stating that 1095189 is both available in servotronic and non-servotronic. I am basing this on my steering gear box’s data plate, which bears the number 1095189, which is non-servotronic and a 1095189 which is servotronic on fleabay.

Yeah that's not a real part number as far as we're concerned. It's like the part numbers cast into differential or transmission housings... I suspect its a master PN from the supplier for the core box, but then the sub-variant is the critical difference. Look up REALOEM and you'll see there are totally different actual PN/s for the E38 and E39.

The E39 boxes like you have already don't have a place to fit the servotronic solenoid controller. Look at an M5 or E38 steering box. It will have a place to bolt a solenoid. "1095189" isn't really germane to that difference except to say they have the same basic family but in fact they have difference in the housings as well. And the M5 has a totally different number on the plate there but is indeed a perfect bolt up fit. So.. basically that number is 'red herring' number. Germans print all kinda numbers on crap for various reasons, often the numbers are useless for our purposes. Thats gonna be one of those.

E53s are rack and pinion aren't they? So probably not too relevant to e39 retrofits unless the e53 rack fits the e39 with a tie rod swap or something.

[geargrinder]

The V8's too? Ok I unlazyed and lookit up. Yep rack for 4.4 too. I'm sure won't work for E39 cuz subframe fit etc which is why they went w the box in first place.

[Qsilver7]

If one looks up the steering box for the e38, e39 , & e39 M5...all 3 steering boxes look the same.

But as mentioned...the e39 sedans/Tourings imported to the US market were not offered servotronics...thus...they will not have #5 seen in the diagram which is the torque converter required to be mounted to the steering box if optioned.

Item #5 is NOT listed in the part number index for the 39 VIN"s imported to the US market....but it is listed for the US e39 M5 and e38s.

Even the ebay link states that the steering box listed is for the e38...again...it's set up to receive the servotronics torque converter.

Hopefully this helps clear up some of the confusion. And this again proves that using VINs and the part number database can help prevent buying parts that may not be plug-n-play just because they "look" like they may...there may be small/slight differences that can be picked up in the database...like the need for item #5 to complete the servotonic's steering box.

{e39 M5 steering box...looks just like the e38 sedans & non-M e39 sedans/Tourings...but #5 is required for servotronics, too}

Maybe I'm just lucky, but I've never a PASoft issue on any of my 3 530is. I've coded the airbag modules twice; once to remove the error from a faulty battery safety terminal (removed from the "equipment" page), and once to remove the error from a replacement module that came from a car with rear side airbags (also on the equipment page).
