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."

Hmm. Interesting. 

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.

The function activates on mine. It dips down and goes backup to its last position.

Hey Sasha if you could send me wd and pin layout this would be fantastic to get working properly on my car as i understand unless you have the electric memory seats this feature will not work properly. Cheers Again for your amazing contributions

Do you have memory seats?

 

I don't, and when I enabled dipping mirror on reverse yes it dipped but it never returned to the same position (close but not close enough so I had to adjust the mirror every time).

I dont have memory seats but it works perfectly everytime. I do have the memory heated seat option activated so I don't know if that makes a difference?

Maybe Skoda fitted the memory motors to your vRS?

Pass and I dont know if there is anyway of finding out? Mine is  65 plate MY16 build.

Do you have auto dimming mirrors? Can you set the drop? Cars with auto dimming mirrors often came with memory motors in them even without the seats. One of the strange option combo’s these cars came with.

It does have the auto dip rear view mirror.

What about side mirrors? There are several combinations of mirrors not including those with side assist

 

6 pins standard electric heated

9 pins electric heated and folding with puddle lights

11 pins auto dimming electric heated and folding with puddle lights

15 pins memory electric heated and folding with puddle lights

You can code mirror drop for any car but on anything less than the 15 pin mirrors, the dip can’t be set, it just drops a little bit.

I'm trying to enable mirror dip in reverse, so far without success. I've done the following (using OBDeleven):

Control Unit: Central Electrics, Long Coding, byte 04 bit 03 "Mirror Lowering with Reverse Gear" - ticked box (shows value 2). n.b. I also found/changed this under Adaptation Spiegelverstellung to set "Spiegelabsenkung bei Rueckwaertsfahrt"='active'.
Control Unit: Driver Door, Long Coding, 'mirror_lowering_with_rear_gear', changed to 'active'
Control Unit: Driver Door, Long Coding, 'position_memory_with_rear_gear', changed to 'active'
Control Unit: Driver Door, Long Coding, 'memory_mirror', changed to 'active'.
Control Unit: Passenger Door, Long Coding, 'mirror_lowering_with_rear_gear', changed to 'active'
Control Unit: Passenger Door, Long Coding, 'position_memory_with_rear_gear', changed to 'active'
Control Unit: Passenger Door, Long Coding, 'memory_mirror, changed to 'active'
Control Unit: Central Electrics, Adaptation, "Menuesteurung Spiegelabsenkung"- changed to 'active'

All of this above did make mirror "lower while reversing" appear in the car settings options in the head unit, however the mirrors still don't dip when I put the car in reverse.

 

I understand (I think from a @SashaGrace thread?) that I need a minimum type and level of mirror hardware for this feature to be able to work. On another thread I found a part number; my car has what appears to be a slightly newer version of that same number, so I'm guessing that it's got the necessary bits .. though I could be mis-guessing how Skoda/VAG matches up incremented part numbers with whether they have at least all the same features as earlier part numbers.

Looking in OBDeleven at the Control Unit: Driver Door, Info shows Hardware number 5Q4959593K, hardware version 007, software number 5Q4959593K, software version 0485, ODX name EV_DCU2DriveSideMAXHCONT, ODX version 001005.

Any idea whether that is/isn't adequate mirror hardware to be able to enable mirror dip in reverse gear?

Did I miss something in my list of coding above?

 

many thanks,

Jay

 

Did you have the mirror switch on the drivers door set to the passenger side mirror?

Hi @PetrolDave, I'm not sure if I understand the question.

The mirror control switch (left, right, fold-in) is in the neutral position (pointing down, labeled "0").

My understanding of the automatic mirror dip feature is that, without touching that control, putting the car into reverse gear should cause both side mirrors to dip slightly (and then return to their previous position upon taking the car out of reverse gear).

Apologies if I'm misunderstanding the question or the feature?

 

Pretty sure on newer cars you need a 'memory mirror motor' to get reverse dipping working properly.

 

The difference is that standard motors have 3 wires to move it, a memory motor has an extra 4 so the door controller can see where it's pointing. Typically, they are only standard with electric seats.

 

For reverse dip to work, it needs to be enabled in the infotainment and the mirror selector should be in the passenger mirror position. That'll be L for the UK and R for Spain.

 

When in reverse, only the passenger mirror will dip, you can set the position whilst in reverse and it should pop back up when moving forwards.

You're misunderstanding the feature - for mirror dip to work the mirror switch MUST be in the position pointing to the passenger side and only the passenger side mirror will dip (to help you see the kerb).

 

As others have said if you don't have the memory option the mirror will dip but when returning will in most cases NOT return to the same position - this is why I tried this feature and then disabled it as adjusting the mirror most times after selecting reverse was a PITA!

Edited 10 February, 20215 yr by PetrolDave

Tried it in mine with no luck - I have auto-dimming mirrors. 

Only thing I can add is that, after trying it, I get an error code for something like "unfeasible mirror position value" which I guess implies it is lacking the memory. 

Just enabled it on mine 2016 no memory seats. Checked my settings matched the OPs, enabled it in MMI and made sure mirror switch was in “L”. Started engine put into R, mirror drops, moved switch back to centre and it returned to original position like when driving off. Happy with that, thanks OP 

Thanks @Powerred, could you post the various changes you made to enable this?

I think I've got all the changes including then making sure it is marked as enabled in the head unit Car settings, and then I've tried with the mirror adjust switch in neutral, in driver-side, and in passenger-side position, and the mirrors simply never dip going into reverse gear. By the way, what do you mean you "enabled it in MMI"?

Just come across this thread.....I'm going to try with my 2019 Scout and see how I get on.  I have auto-dimming mirrors, so there is a cats whisker chance of getting it to work.  If I'm feeling brave, I'll try on my husbands SE1.0 - and see how much mileage I get....getting "implausable mirror position" error message will probably mean no go....but if I get it to work, I'll post my config on here.

MMI - multimedia interface, or head unit (gotta love an acronym)

My settings match that of the first post. Sorry I cant be of more help.

It’s weird how this works on some and not others. It worked a treat from factory on my 2017 A3 (no memory). I enabled it in the wife’s 65 TT and it worked too well, planted the mirror to the floor and gave no option in the MMI. All similar platforms

I’ll say it only once more, those who have it working just via coding, try setting the dip position and you will see that it doesn’t work as it’s supposed to. It’ll drop 10mm and if you are lucky it’ll come back but the mirror motor doesn’t have the memory unless you have 7 pins to the motor which was in all but the rarest cases only fitted to cars with power seats. The Octy is not like the Leon/Golf where almost all the mirrors have the memory motor. The Octy, unless specified with the memory mirrors as a standalone option which is incredibly rare and only available on certain trims at certain times, not throughout the production run, doesn’t have the ability to enable this feature only via coding. It’s easy enough to fit the memory motor if you are handy though and then it’ll all work as it should. I’ve fitted power seats with driver memory and memory mirrors to my car and it all works as it should off the key and driver profiles.

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.
