Mirror dip in reverse?

[bigcw]

Should my 57-plate A6 Avant Le Mans do this? Ie drop the passenger mirror when reverse is selected?

A Passat-owning mate told me I had to program it by selecting reverse, select passenger, set to position, set back to middle, then into drive.... blah blah. Whatever I try, I can't get it to do it.

Is it possible that the option has been disabled on my car as I have the reversing camera? Would VAG-com be able to enable it?

Cheers, Chris

If you have the memory seats option then it should be doable with VAG-COM.

[bigcw]

Ahh, I don't have memory seats. Are they required for mirror dip?

I have a 10 plate, without memory seats, and would be interested in this feature too.

Something I miss from my Touareg.

I have a B8 A4 without memory seats.....and I enabled it on my car via VCDS.

The difference to a car with memory is that I can't set the tilted position. It goes to a defaut setting....which just happens to be fine.

It's activated by having the mirror switch pointing to the passenger mirror. When reverse is engaged it drops and when you drive forward over about 10mph it comes back to your normal position.

p.s. For a car with memory seats, I thought it was standard.

Ooh, nice.

'Needle Sweep' too...

Thanks Scotty!

[Scotty]

I've made loads and loads of tweaks ... and then when they had my car in the connected it to their computer and they were all removed so I've had to re-do them....and the car's in tomorrow for the 3G software upgrade so they'll all be gone again!

Hi,

Which controller is the mirror dip option in ?

Cheers

[Scotty]

42 - driver's door

Thanks again Scotty. I attempted the needle sweep and mirror dip earlier today but failed miserably.

Needle sweep for example -

[17 - Instruments]

[Coding - 07] -> Long Coding Helper (I don’t have this option)

-> Byte 1

Bit 0 - Check the box for "Gauge Test/Needle Sweep active"

And I looked into mirror dip from the controller you mentioned in the above link but again, no long code helper.

I have only just bought the VCDS and am running the latest S/W version. What am i doing wrong, I have also asked Ross-Tech and searching the forums, maybe my car controller is too old.

Errrm not sure. Maybe Long Coding is on the Can-bus cars only. Ross-Tech are very helpful so hopefully they'll know the answers.

We didn't always have the long code helper and that meant you had to do a lot more bit/byte calcs and you had to be a lot more careful.

Also bear in mind that just coz I have certain options on the A4, it doesn't mean they're available to you.

Ross Tech got back to me last night and confirmed that the Instrument Cluster in my A6 does not support Long Coding and that i need to add the total sum of options in the proper place from A6 wiki -

http://wiki.ross-tech.com/wiki/index.php/Audi_A6_%284F%29_Instrument_Cluster_%28through_MY_2008%29

My current instrument coding is 2308443 so if im reading this correct, i need to add 3 for the needle sweep to work. So i tried to change the coding to 2308446 but VCDS prevented me from doing this as it errored and said the code was out of range so i have left it now.

I'll see if i can find another changes in the forums that i can make. Cheers for your help though.

[Scotty]

Do you understand binary?

Do you know what bits 2308443 has turned on ?

Adding 3 sounds weird as that's 11 in binary i.e. it's setting two bits on rather than just one.

You normally add a number such as 1, 2, 4, 8, 16, 32, 64, 128, 256, 512, 1024, 2048 etc

This page is for the TT but it's a nice simple was of understanding what you're actually trying to do : Codes for programming TT locking system

The number 2308443 can be expressed as:

2097152 + 131072 + 65536 + 8192 + 4096 + 2048 + 256 + 64 + 16 + 8 + 2 + 1

So, the answer is: 1000110011100101011011

This should the last two bits are on. If you add 3 to it :

The number 2308446 can be expressed as:

2097152 + 131072 + 65536 + 8192 + 4096 + 2048 + 256 + 64 + 16 + 8 + 4 + 2

So, the answer is: 1000110011100101011110

So you've in effect turned one bit on and one bit off

Strange!

I haven’t used hex/binary (conversion) in 30 odd years and must admit didn’t even think I had to convert before adding to the original values. I think I need to read the VCDS manual before I attempt any more mods.

I’m only guessing I need to add 3 as this is the extract from the wiki and the link in my previous posting -

xxxxxx?: Illumination

§ 0 = Needles OFF and Scales OFF (Term. 15 ON / Term. 58 OFF)

§ 1 = Needles ON and Scales OFF (Term. 15 ON / Term. 58 OFF)

§ 2 = Needles OFF and Scales ON (Term. 15 ON / Term. 58 OFF)

§ 3 = Needles ON and Scales ON (Term. 15 ON / Term. 58 OFF)

Like I said the original coding in the controller is 2308443 so if I had to add 3 to this, in binary, that is 11 so adding this to the original coding I get 2308454 or am I being really thick and way off the mark? (dont answer that)

I didnt really understand when you say 'So, the answer is: 1000110011100101011011'. Cheers

Aha ! A few things :

[1] That's not needle sweep. That's simply was is lit up.

[2] In that example the question marks represents a value so it would simply 0,1,2 or 3.

You're now mixing the addition of binary. You're adding 11 (eleven) if you do that.

"The answer is 1000110 etc " was just a cut and paste from a web binary/decimal convertor but I was hoping to show how the car turns things on and off. Basically a 1 means some feature is enabled and 0 not. We only note it in decimal or hex to bac it easier for our human brains.

Anyways the first thing you need to do is find [a] can you do needle sweep on your car what the code change is.

The function differs. Like the automatic tilt down function on the passenger mirror is part of the electric seat with mirror memory option. If your car does not have electric seats then you certainly will not have this function.

Hi,

Sorry but your post has confused me. It seems you're saying that my mirror doesn't dip when I select reverse when infact it does. :confused:

[phearnde]

Thanks for this.... Just enabled it on my 2010 Registered A5 2.7TDI, without memory seats and it works fine

Only thing different for me is that it is controller 52 (Passenger Door Electrics), guess that's because my A5 is UK model, right hand drive.

Any how, it works

:-)

PS: This is the first thing I have tried configuring, using VCDS, so double pleased.

Hi, I have an A6 (C6 4F)...

Mirror does tilt on reverse... without memory package... does remember only tilt setting per key...

I have Std.elec seats, from factory my car had come with elec.folding/adjust/heated/dimming side mirrors...

But the one on passenger side had a memory mirror on it... which has 7 wires to the mirror adjusting motor vs 3 wires to mirror adjusting motor...

Once I did code change in module [52] +128 to enable memory mirrors...

All work good for me...
