Hi @SashaGrace , I understand this. I looked back through the thread and I don't see part numbers that a car would have to have in order for mirror dip to be able to work. Is there a list of compatible part numbers somewhere?

 

@Powerred and @Ecomatt Would you please be so kind as to post the hardware and software versions of the related components in your car? (I guess this is OBDeleven Info; I report mine below. I assume similar is available in VCDS, etc).

 

Thanks.

Looking at the Info for the Control Unit: Driver Door on my car in OBDeleven I see:

System Description: TSG FS

Identifier: J386

Hardware number: 5Q4959593K

Hardware version: 007

Software number: 5Q4959593K

Software version: 0485

Long coding: 001C0920DE00020000001100

ODX file: Use latest

ODX name: EV_DCU2DriveSideMAXHCONT

ODX version: 001005

Protocol: CAN: UDS

 

And Passenger Door:

System Description: TSG BFS

Identifier: J387

Hardware number: 5Q4959592K

Hardware version: 007

Software number: 5Q4959592K

Software version: 0485

ODX file: Use latest

ODX name: EV_DCU2PasseSideMAXHCONT

ODX version: 001005

Protocol: CAN: UDS

 

  

 

 

This is mine. I have since deactivated the mirror dip function, as I found it more of a hinderance than help after a while.

Great, thanks @Ecomatt.
Could someone please comment on the slight differences in hardware?

TSG BFS J387 (in both cases)

5Q4959592K (mine) vs 5Q4959592B (Ecomatt's)

Does a different letter at the end signify meaningfully different characteristics/ capabilities, or just older/newer versions of "the same thing"?

thanks,

 

It's impossible to know exactly what changes between part numbers. The final letter can denote:

- a newer part

- an improved part

- similar parts with different PR codes/features

- a change to how it's manufactured (cost cutting)

 

Anyway, here is a scan of a Superb with a similar (to yours) K rev module and factory fitted memory motors here: https://www.briskoda.net/forums/topic/481377-amundsen-upgrade-to-google-maps-with-live-traffic/

 

That suggests the door controllers should support dipping. You might want to check your coding though, your previous post gave this lcode:

001C0120DE00020000001100
        XX     <-- byte 04

DE = 1101 1110
            X  <-- bit 1 is ticked

 

Instructions clearly state bit 1 should not be ticked if memory motors aren't fitted. Maybe try: 001C0120DA00020000001100

 

If that doesn't work, I think you'll need to retrofit a memory motor and wiring to get this working properly.

I’ll do it after work.

 

One thing to report, if it dips while manoeuvring and you don't drive away or put it back it stays down and doesnt remember to come back up. Effectively only making it useful 50% of the time

Not sure if this is what you wanted or if it helps any more. Also to update turns out it does return to original position with ignition off so my previous post was incorrect. It works 100% as it should (just like my 2017 A3 that was a factory enabled feature sans memory seats etc)

4E0959577C is the mirror motor I used which was from a Superb. You then need the plug and extra wires or add them yourself. WD is available on ETKA or I have a pinout somewhere.

Thanks for this detail. I've looked in OBDeleven's Info for the doors, and I get the feeling that it can't read the mirror motor part number (or I don't know where to look for it).

Is there a software way to see what mirror motor part number is installed in my car, or do I need to take something apart to figure it out?

cheers,

Thanks. I've tried it both ways; no change.

I assume, even if it won't end up working completely (the "it goes down but doesn't come back up" that more than one person has mentioned) that I ought to at least be able to get the mirror to dip down.

So far, I've gotten .. nothing. Reverse gets me reverse (which, let's admit, is not a bad thing 😅) but has no effect on the mirrors.

So I figure I'm still doing something wrong in the coding.

I've followed the settings as discussed here, and in this OBDeleven forum thread https://forum.obdeleven.com/thread/1017/mirror-dip

One thing, is it necessary, once the coding is done, to put the car in reverse and set the dipped position? That is, that the coding just turns on that it would remember a dipped position, but not that it does dip to some (default) dipped position unless/until you tell it what that dipped position in reverse should be by adjusting the mirror yourself while in reverse gear?

The mirror motor is a 'dumb' device so doesn't report it's part number anywhere.

 

You'll probably be able to check by removing the passenger side mirror glass as you'll be able to see the motor. If you can't see the part number, count the wires, 3 is a non-memory version, 7 has memory

 

I believe there are different part numbers for LHD and RHD cars so double check before getting the part mentioned by Sasha

With a memory motor, it should revert to the saved position. It's plausible the initial reverse position is the same as the nomal one so it won't work until you've put the car in reverse and moved it whilst in gear.

 

Without a memory motor, I'd expect it to just dip an amount. As I mentioned before, I think something changed in the control module which means that newer versions no longer support dipping on non-memory motors..

 

As above, you need to take the mirror glass off to check the motor physically. Luckily the mirror motor isn’t drive side specific, just car side specific so that’s the right one for the passenger side

I've ordered a USB borescope in hopes of being able to identify the existing motor without having to remove the rearview mirror glass. Will report back in a few weeks when it arrives from China!

Erm, you know it's a 30s job to remove the mirror? I'm all for new toys but your fingers are probably better for this

 

 

Yes, I know. Call me excessively conservative (or call me an engineer with a few too many years of experience with products that need to last for a very long time), I'm just not a fan of physically removing things that work on pressure clips any more often than necessary (when if they do break/wear out the cost is high to repair/ replace them). Call me old fashioned; I like screws and things like that which, at extremely low cost, are more-or-less engineered to last about 1000 times longer than the larger, more expensive product of which they form a part.

And, yes, new toys... :-)

Good luck; the part number is listing on the front of the motor butted up against the glass so you’ll have to go in from the bottom right corner to see the wiring loom. If you have 3 wires (which you will if it’s not working correctly) you’ll need the mirror motor. I’ll send you the coding from my Superb which will likely have the same door controllers as your car when I collect it so you can see the exact coding.

So, I got the borescope. Not sure whether what I was able to see shows me the needed part numbers. Here's what I could see:

7 537 A U34 04S

5E1 857 407 CR

LH 2/2 19357 >ASA< GERMANY DON

and a couple of grids - one 6x6 and the other 13x6 with dots in some of the grid cells.

 

The 5E1... number I find on a Russian car parts website: https://detali.bitavto.ru/catalog/detail.php?ELEMENT_ID=533565#product-pictures-533565

The far end of the connector clearly has lots of wires coming into it; whether all of those wires actually connect to anything inside the mirror assembly is another question.

Hm, there are actually several different of these parts on that website, here's another with better pictures: https://detali.bitavto.ru/catalog/detail.php?ELEMENT_ID=430543#product-pictures-430543

 

I apologise for being fairly useless and asking so many questions.

Does the above help identify the mirror motor?

n.b. this is inside the driver's sideview mirror. (It dawned on me afterwards that maybe I should have looked at the passenger side mirror?)

 

The part number you want is on the face of the mirror motor.

 

You can see if in yellow here:

Anybody done any testing on octavia mk4 to get this feature going without memory seats installed?

Hi guys, 

first of all big thanks for what you doing and sharing info. This is my first post ever here.
Im new in Skoda "customization" and  this forum is filled with very useful and precious information and nice helpful people

Was looking at the Skoda Owners Facebook page today, and a member Mike Holroyd seems to have finally sorted the issue with the dipping passenger mirror. I know other members on here have struggled to get this coding to work on their Octavias, so I thought I would post this, if it helps.

"Passenger mirror dip in reverse - Octy 3 (MQB)
Had a play with VCDS on the Leon this afternoon (same as the Octy3) and finally managed to get the reverse gear passenger door mirror dip to work after months of trying. Yes I know it's been sorted on a Seat, but I'm putting this on here as I have seen folks asking on here too as to why it isn't working on their Octy 3. Found a bit of info on an Audi forum, and everything now working perfectly
As well as the well documented changes to the 09 Central Electronics module (access code 31347), there is a further setting in 52 Passenger door electronics - it appears that switching on the mirror dip in central electronics can also switch on the "memory mirror with memory seats" option in the door controller, and with no memory seats fitted, if that is ticked, the dipping function won't work. This setting is not documented anywhere I could find! So the complete coding for activating the mirror dip is:
Controller 09 - Central Electronics
16 - Security Access - enter 31347
10 - Adaptation
(15)-Access control 2-Spiegelabsenkung bei Rueckwaertsfahrt - change to active (this switches function on)
(20)-Access control 2-Menuesteuerung Spiegelabsenkung - change to active (this switches on an extra entry on the mirror option in the settings menu in the infotainment screen) 
Controller 52 - Passenger door electronics
Long coding -> Function 07 (no access code needed)
Byte 04
DEACTIVATE bit 1 Mirror memory function (with memory seats)  installed/active (NOT TICKED - if it is ticked, it will not work)
Activate bit 2 Reverse gear mirror dipping active (TICKED)
Activate bit 3 Position memory for Reverse Gear Mirror Dipping active (TICKED)
Close controller, unplug VCDS, switch off ignition, lock car, unlock it again and switch ignition back on to reboot.
This coding will be exactly the same on the Octy 3 - hope it helps someone out
Remember, the mirror adjustment switch needs to have the left mirror selected for this to work."

Just to let you know, unfortunately  this won’t work. The standard mirror motors on the Octy have 3 pins in them, one for left/right, one for up/down and one for ground. No memory function. To make this work you need the 7 pin motor with directional control memory. I am building one now for someone and I have one in my car. This is the only way to get this to work as the standard hardware isn’t there for it on these cars. It’ll dip just with coding but it has no way to be set or remember the previous position. 7 pin motors aren’t expensive and I can provide a WD and pin layout.

 

I just want to confirm that this is NOT working (as ms. SashaGrey predicted ) on my Octavia III 2015. Don't have memory seats. I went through all the steps but at the end I have just lil dip of mirror, not possible to finetune the dip. On reverse gear, it dips a bit, when you go forward then and after you reach certain speed, it goes back up. I found out you can push the "get back" mirror to original position with turning the controller to "0" position. 

 

I just wanted share my experience and try to help others as you do guys 

 

Big thanks again

This has been known and posted on here since at least 2016 when I purchased my first Octavia - it didn't have memory seats so I had the same lack of success when I tried to setup mirror dip on reverse.

 

My current L&K Octavia has a memory drivers seat so mirror dip on reverse works perfectly.

 

IIRC @SashaGrace discussed this issue at length as one her many retrofits.
