Mirror control and passenger mirror dipping

[hufodorp]

Hi all,

I have 2 things I want to get an answer for.
Car is post facelift 2.0TDI. Year 2010. S-Line Special Ed 170BHP. Lighting pack installed

1st. Control for mirrors:
If I set mirror control knob left or right it happens in both position. When I flick the switch up, right or down then mirror starts moving and then stops when I let the knob go. If I flick it to left then the mirror starts going to the left but never stops just keeps going when I let the switch go.
What can cause this or is it normal? (can it be sticky switch)

2nd. passenger mirror dipping:
I have only long coding available on passenger door. I enabled bit 3 on byte 4 but nothing happened. My PR code for mirrors are:
PRCode: 5SJ = Left exterior mirror: convex
PRCode: 6TS = Right exterior mirror: aspherical large viewing field
PRCode: 6XD = Exterior mirrors: electrically adjustable/heated

Thanks for help in advance.

1st, not normal, would agree with you that the switch is faulty.

2nd, you have to enable at Byte 4 Bit 2, check the box for reverse gear dipping active.

Byte 4 Bit 3, position memory for reverse gear dipping active, will do nothing as you don't have memory mirrors.

without memory mirrors all you can gain is a default amount of down/up movement that is of some limited use but you still might have to tweak the position slightly each time you select reverse.

also, if you don't already know, the mirror switch has to be in the left mirror adjust position for dipping to work.

Check for a fault code if possible for the mirror issue, as it could be a faulty door control module.

I had a look but couldn't find error in driver's door or passenger's door. Should the error be in somewhere else?

Is it possible to test the switch position through VCDS?

Thanks for the info. What is the indication that I don't have memory mirror? If I buy another mirror and replace only the near side is that enough or should they be replaced in pair?

[c4a5er]

Before you go to the expense try enabling Byte 4 Bit 2 as in the earlier post, you may find the default amount to be enough that you could manage with that.

I don't know of any reason to change both sides if you only want the near side to have memory function. If you replace the n/s one you will need additional wiring between the passenger door module and the mirror.

I had tried Bit 2 but it isn't move it down enough :( Do I need to replace the door module? What kind of mirror to get? Which shop/scrap yard would you suggest?

No need to change the door module..... Have a search, mirror dip has been covered at length previously, you should find an excellent contribution by gupsterg where he investigated the option and IIRC concluded that all that was required was a mirror with inbuilt memory function and some wiring.

Is this (http://www.vwaudiforum.co.uk/forum/showthread.php?133553) that you are talking about?

Only for prefacelift cars. Facelift cars can have the option regardless of mirror spec.

Chris,

Do I need to replace the mirror or not? I'm confused now. :(

With the car in reverse and the mirror dipped, try moving it the position you would like it to be in. Take the car out of reverse, allow the mirror to return to the "normal" position and then put it bask in reverse. Hopefully it should go to the new "reverse" position you selected

It does dip it but only just a little downwards. Seems doesn't remember for position. What bits to enable now? Do I need to enable memory for reverse dipping?

:D c'mon mate keep up.....this was covered in post 2...."you don't have memory mirrors", you can't enable something you don't have!

:confused: :notworthyI know sorry for that, I'm just confused as Chris said "Facelift cars can have the option regardless of mirror spec."

Your door module supports mirrors with memory function but your non memory mirrors don't have any position feedback.

So when you chose the reverse dip and memory option in your door module selecting reverse instigates the dip but because there's no position feedback from the mirror motor the mirror just stops.

In the thread you found you'll find reference to the various mirror options and film of position memory mirror operation, up/down, left/right etc.

TBH i've not re read the whole thread but seem to remember PR and part numbers in there somewhere if you really feel that you must do a retrofit.
Personally I managed by letting the standard mirror dip to it's default drop and then manually increased a little. Bit of a pain having to do it each time I reversed near a kerb but not enough to make me unhappy enough to go to the trouble/expense of changing mirrors.

Hi Hufodorp,

On the 2004 -2008 cars memory mirrors are a definite must to have reverse dipping when the door module has been coded and you can set the amount and direction of dipping only per key.

On the 2009 - 2011 cars reverse dipping will work with code change to door module without having memory mirror unit but only to a predetermined range of dip downwards and you can not set how much it will dip or direction regardless of which key.

If you fit a memory mirror unit you will get 1 setting per key.

You have 6XD mirrors so you only get predetermined range of dipping, if you had 6XF then you'd have memory mirror units.

Reverse dipping is part of the memory package, view page 45 & 52 in this brochure Link:- https://www.audi.co.uk/content/dam/audi/production/PDF/UsedCars/Refresh/A6/A6%20-%20November%2009.pdf

Hi gupsterg,

Thanks very much for the info. Looking the brochure it seems that I need to have electric seat also. Can I get only the memory mirrors? If yes 6XF is the one that I need?

[gupsterg]

There was a thread on a US forum plus some info on a German 4f wiki where mirror tilt on reverse was gained by fitting just the memory mirror units and no other parts of memory package or elec.seats. I only found the info after lots of delving around, there are just so few threads/info plus also if memory serve me well the US poster fitted a folding switch but did swap both mirror units to gain fold in feature.

I also researched into if the car was aware I had elec.seats and I don't think it is, read post 134/135 (http://www.vwaudiforum.co.uk/forum/showthread.php?133553-C6-Mirror-Tilt-on-Reverse&p=763432#post763432), mine is a 2005 car.

But above info is in relation to 2004-08 cars and have not read any info on 2009-11 owners installing memory mirror units (not to say it hasn't been done or isn't out there) but you can see some kind of software change in the door control modules has happened between the 2004-08 and 2009-11 cars to allow mirror tilt even without memory mirrors and again it works on cars without elec.seats.

You'll find 6XF P/N's in this link, Link:- audi-a6-s6-avant-quattro-a6q-eu-2010-interior-exterior-mirror-cover-for-door/ (http://www.partsbase.org/audi/audi-a6-s6-avant-quattro-a6q-eu-2010-85740-interior-exterior-mirror-cover-for-door/)

4F2 857 409 AJ 01C (Left) 4F2 857 410 AJ 01C (Right) are without the LEDs on base.
4F2 857 409 AM 01C (Left) 4F2 857 410 AM 01C (Right) are with the LEDs on base.

You will also end up gaining fold-in function and the little LED lights under the mirror if you get the ones with it.

You may have to fit a folding mirror switch to door as well.

I can only share what I learnt from being involved in the other thread, I never fitted a memory mirror unit to my car it just happened to have one by shear fluke. The other side is not a memory mirror unit but just auto dimming/heated/folding I took some pics of it in post 122.
