mirror dip on reverse not working

[lordnikon]

So I tried the mirror dip on reverse app for 10 credits. I enabled the function to ON.

In the car setting menu, I enabled 'lowering in reverse'. I put the mirror switch to R then I shifted into reverse. Nothing happens....

I also tried having the ignition ON and OFF and still does nothing.

Any thoughts?!

Have you done the “training” aspect already? You put it in reverse, put mirror switch to R, then adjust mirror to where you want it. Then you can go back to D and it should go back to where it was.

[lordnikon]

Yup did that. It does nothing. Apparently I'm told the mirrors need to have a memory function in order to work. My car does not have the folding mirrors.

Lord: Not all mk7.5s are created equal - as I suspect that you know.

A really important question for this tweak is: do the mirrors on your car have the required memory modules to store the co-ordinates for the mirror positions on the return function?

Might be prudent doing the test below to confirm whether the memory modules are installed (apology for the old software on the screenshots, but it's exactly the same process with the current OBD11 version SW):

Note: the X/Y coordinate values can be different (this depends on where the mirrors are positioned), but they can't be 255% if the memory module is installed

Hi Don, I checked and my car does not have a memory module. I guess I'm SOL.

It should still dip. But it won’t likely return to the correct position without the right hardware.

When I first got into tinkering with coding, I coded my 16 GTI for mirror dip in reverse. It dipped but wouldn’t return to the correct position. Later I installed power folding mirrors, and the mirror returns to the correct position now.

Shot in the dark, but have you tried resetting the mirror settings to defaults, and then enabling the dip again?

[lordnikon]

I understand however if it doesn't remember the previous position I don't see a point to it.

And that’s one of the reasons why I bought the power folding mirrors. And I agree, if it doesn’t return to the correct position, there’s no point.

I know this is an old thread but I’d like to contribute.

Like the saying goes, not all GTIs are made equals, even in the same trim.

To enable the mirror dip, all these requirements must be met:
  1) Modules: both driver and passenger modules, must the high line
  2) Mirrors: must have the position memory capability
  3) Settings: the car configuration adjusted to enable it

Modules
From what I've seen in other forums, it's pretty clear that the modules must be a 5xx one, being very consistent to see this specific one work for people:

• 5Q4 959 593K
  

Though the last letter might vary.

Mirrors
The sure shot are the folding mirrors, they seem to be top of the line.
I personally have never seen anyone say a folding mirror didn't dip.

But for non-folding, let's call them low line mirrors, it's a lottery. I don't see people saying P/N for these, they just go for the folding if theirs don't work.

Configuration
It's seems to be just those 4 things posted in this thread.
I can't vouch because I couldn't get it to work in my car.

Final thoughts
Failure to have any of those 3 requirements will cause it to either: not work at all or work so so.

So so will happen when the configuration gets enabled, but either the modules aren't high line, or the mirror does not support the memory function.
In this situation, the mirror might dip, but it will either:

• Not return to the original positional after disengaging reverse or driving forward
• Return to a position not exactly as it was

In my specific case, I could not get it to work at all in my car with the original optionals.
it's a 2020 NAR GTI (MK7.5 ).

All I got was a RH side mirror that would eventually not work at all, or would not work when reverse gear was selected.

I do have high line modules:

• 5Q4959593K (driver)
  
• 5Q4959592K (passenger)

I also checked the passenger module for the mirror memory, the Live Data confirmed it’s there.

I did and re-did the configs over and over, in different ways, different sequence, rechecked everything, but it never worked.
But my mirrors are non-folding, and I think this was my down fall.

After fiddling with the Basic Output test, I got a fault: Mirror position sensor malfunction.

I'm not sure if I'll exchange the mirror in my car, if anyone is curious out there.
Mine does have heated mirrors + blind spot monitor, but there aren't any Golfs, in any trim, that have all three: folding, heated + blind spot.

That is doable, I saw a guy in a forum that ported his blind spot mirror to a folding mirror, and added the 2 wires to the loom, but I already added the puddle lights to my car, and it was a long nightmare to get new wires through the mirror structure, but totally doable (it was my first mod, maybe I'm better now?)
