Hi Guys,

 

I am attempting to fit the reverse tilt mirror module 3D0959578C (chinese part) to my Mk2 FL Octavia VRS. I have the correct door module 1T0959702N that supports the mirror down function. 

With the mirror motor I received a wiring harness and after following the steps in this Russian retrofit guide https://www.drive2.ru/l/3589798/ I tested the fitting and have a problem.

 

The problem is that when adjusting the mirror it moves the wrong way. So when I use the mirror adjuster it moves up and down when I am actualling trying to move left and right and similarly when I try to adjust left and right it moves up and down :( And for the mirror tilt on reverse it moves side ways instead of down :( 

 

The retrofit guide in the link above was for the memory motor fitted to a left hand driver car. However, since cars in the UK are right hand drive I think the wiring configurations are somewhat wrong? 

 

This is the pin assignment I followed

 

| plug in the mirror motor     | plug into the door unit _ | 
| ___________ 1 ______________ | __________ 2 _________ | 
| ___________ 2 ______________ | __________ 4 _________ | 
| ___________ 3 ______________ | __________ 1 _________ | 
| ___________ 4 ______________ | ___ _____not used ___ | 
| ___________ 5 ______________ | __________ 3 _________ | 
| ___________ 6 ______________ | __________ 5 _________ | 
| ___________ 7 ______________ | __________ 9 _________ | 
| ___________ 8 ______________ | __________ 12 ________ |

 

Anybody please point me in the right direction? I am not sure how to get the correct pin assignments for my door modules? I know our resident retrofit masters @langers2k and @Eddie-NL has done this retrofit before can you please share the wiring configuration for this please Guys?

When I did this, I replaced the entire mirror for one with power folding and the wiring for a memory motor already fitted.

 

Not sure if these will help, this is an Octavia wiring diagram that also shows the pin layout on one side:

 

And this is a Golf version which does show the pins both sides:

 

 

The only obvious difference between them is pin 2 and 3 appear to be reversed.

 

However both appear to be vastly different to the drive2 post.

Thank you for the quick and detailed response @langers2k i shall have a look this evening. Also mine has the folding mirrors, not that it helps the situation hopefully get it sorted. 

Ok had a study through the wiring diagrams and it is coming across to me mega confusing lol

 

@langers2k would you by chance know pin assignments for the memory mirror plug (meaning what does what?). Perhaps I can then figure which colour wire goes to which pin? 

 

Just to confirm do you have the same colour plug in yours? 

 

 

 

Just reread your first post as I'd misread it first time.

 

Try swapping pins 2 and 8 on the mirror side.

Where did you get the motor from and how much was it?

Thanks Pal. I tried it there and slight progress. The mirror is moving correctly side ways so left and right is fine. However up and down is reversed. So instead of up its moving down and vice versa.

When I fitted the folding mirrors on my car I had a similar issue with the drivers mirror. I ended up playing round with the 3 wires (red, brown/white & white) that go to the motor to get it to work correctly. Took a couple of attempts to get it right and the wires ended up in completely different positions to the wiring diagram. 

Thanks man but it seems swapping pins 2 with 8 is messing up the reverse down function :( i swapped it at the motor bdw

 

also in regards to your previous question got the motor from Ali express

I would put 2 and 8 back the way they were and try different combinations of the wires in 4, 5 & 12. These are the ones for the motors.

Ok pin in the plug for the motor is blank mate. Basically all the operations are reversed i.e. movements and mirror down

@dilksie tried 4,5 and 12 combos and no change unfortunately :( got to be some way of sorting this :( 

 

@langers2k anyway of checking what pins from your motor 8 pin go into to the door modules 16 pin? 

Edited 22 April, 20188 yr by singh946

Only if I take my door panel off.

 

I've checked and I haven't any pictures from when I fitted mine unfortunately. I doubt the wire colours I have will match the loom you have. Still, I'll try and check the mirror motor side and see if the colours tally up with the Octavia diagram I posted previously.

 

If they don't, it's doing to need to wait a few weeks until I've got time to take everything apart.

Oh yeah definitely wouldnt like you to take your door card off as it will be too much effort :( . As said if you have time probably be easier to check the motor side as you said? Thanks for helping out while you at it could you please take a close up picture of the plug with all the pins visible so i can compair them with mine. Sorry for being a headache.

ok had a play around with the pins at the door controller side as it was easier to swap them around there instead the motor side. Got the mirror X/Y orientation sorted  i.e. left and right was as it is and top and bottom was same aswell. However, the memory mirror dip (automatic orientation) was all of the show? It would move in any direction basically :( So back to square one basically 

Edited 23 April, 20188 yr by singh946

so the left/right and up/down all work as per the switch? Which wires have you swapped around on the door controller? 

 

By the way, I did some searching on the part number you have fitted and it comes up as a part for a Passat.

Hey @dilksie the pins on the door controller side that got the orientation working fine as per switch were Pins 4,5 and 12. The wire colours were Brown / White, White and Red. So I had to swap the wires from 12--> 5 or 4 (i don't remember lol)

 

However before I began all of this, I removed all the wires from the new memory motors. So one by one connected the wires individually to see which wire did what? By the end of the night 11:30 lol what I thought got the orientation working fine as per the mirror switch I strongly believe was the memory reverse dip as that worked fine from the beginning.  As the memory dip was still working when I only had wires in pin 4,5,12 but it was all over the show. It was behaving erratically and at one stag though it was going to eat the mirror haha

 

So I believe pins 4,5 and 12 are for the reverse down mirror tilt or you can say automatic adjustment. I am going to play around with pins 1, 9 and 2 tonight.

If you look at the diagrams above 4, 5 & 12 are for the adjustment motors, 1, 2, 3  & 9 are for the feedback for memory positions.

Yep it seems. However it was a real nightmare trying to get the memory positions to work with fixing the correct XY orientations by the switch. The think is the diagram doesn't show which pins it goes into the motor side switch :( Think I am going to start again by fixing the mirror positions I got yesterday.

Just ordered a motor for my car. Hopefully a solution can be found to the problems

Hopefully yes man, has been melting my head and hurting my fingers trying to remove the pins from the connector every time I try a different combinations lol

 

Here is the progress so far after as I sorted out the manual adjustment of the mirror at Pins 4,5 and 12. Still scratching my head trying to figure out the correct combo for 1,2,3,9 i.e. Memory dip as they certainly don't seem to work any more (it goes bonkers rotating all over the place). 

 

 

The memory motor will only work on original positions for 4,5,12 even though they are totally independent in the workings. I am going to try again after work a different combo for 1,2,3,9. Will report back my findings. Hopefully all sorted before you install your motor

Hi singh946,

 

I am in the same situation as you were, at least on your last post.

Have you found a solution yet?

 

I have a LHD car and my feeling is that the passenger door module I bought is from a UK RHD car which was on the left door. Maybe this is the root cause of the problem.

 

Thanks!

singh946 has now sold his car and I don't think he posts on here anymore. I have tried various solutions but unable to get the mirror to move in the correct directions with the switch but have learned to live with it for the time being as the reverse dip works correctly. I am on the lookout for the correct module from the left mirror of a RHD car though so I can get it working correctly and re-enable the mirror synchronisation. 

:))) we could switch the modules between us and we will both be happy. I'm just 1700 miles away

Can you tell me the pin assignment you used? Maybe I could get the reverse dip to work correctly on mine also.

Basically, I don't think you can fix using the 'wrong' mirror by just wiring changes :(
