Dynamic indicating conversion

[fest0r]

I’m thinking about doing this conversion on a 2014 pre-facelift A6 Avant and there seems to be conflicting info.

1. Are all facelift Avant tail lights suitable (in conjunction with third party adapter kit) or is it only specific units/part numbers?

2. I see a lot of adapter kits mention the supplied coding dongle is “single use” so can the coding be done in VCDS?

3. My central convenience module is running software version 521 so it should be OK for indicator recoding, but if I also want dynamic hazard function it needs to be 560 or above. Would I be asking my dealer to update just this module or can it done automatically with a system wide software update?

4. Where is the best place to get the adapter kit? A lot of listings state “not suitable for right hand drive” …is this just for the coding dongle?

I know that M1tchy on the A7 forum has either converted the rear lights in his A7 or has researched it, perhaps contact him he's a really helpful guy.

I followed Mitchy's pioneering efforts through both types of conversion so any advice from him will be greatly appreciated. I did notice the second adapter kit he bought mentioned LHD only although it still worked.

There now seems to be an abundance of adapter kits… some stating A6 only, some for A6/A7 and others that work on the whole range. There also seems to be a discrepancy between the CCM software required.

Kufatec suggest 551 and some of their kits are LHD only:

Hazzy Dayz want a minimum of 510… or 560 for hazard function:

A6 4G Facelift Rear LED Lights with Dynamic Indicating - Supply & Fit (http://hazzydayz.com/a6-4g-facelift-rear-led-lights-with-dynamic-indicating---supply--fit-6774-p.asp)

I would guess it’s due to different kit requirements, but there doesn’t seem to be a definitive answer. I also can’t find info on updating the CCM software or if a new module is actually required. I was hoping to pick up a used set of facelift tail lights from ebay and a suitable adapter kit… it could half the cost when compared to a Hazzy Dayz full install.

The difference between left and right hand tail lights (from the investigations I did for my A7) were which side the fog light is located. It should be on the same side of the car as the driver sits so it's more visible. However, it's perfectly acceptable to have one on each side which negates the left and right handed issue like on the A7 which now has European style or US style only, no left and right variants. I assume it's the same for the A6 as the rest of the A6+7 are the same.

As for the CCM and coding, I don't know I'm afraid as mine were plug and play

Thanks for the info. It seems the A6 has US and non US spec variants and both have fog lights on each side. What’s not clear (to me) is whether there are similar looking facelift clusters that cannot provide the dynamic function at all. Does the facelift SE (without dynamic indication) use the same clusters?

Did your adapter kit come with a coding dongle or did you alter settings in VCDS? If nothing was required then your kit seems to work differently from the ones I have seen for the A6. Do you have a link or company name?

Thanks again :fing02:

So as I think you know i initially did a semi dynamic upgrade before fitting the full facelift tail lights. I got my semi dynamic adapters and then the full dynamic lights and adapters from https://www.active-sound.eu/en/index

The bloke who owns and runs the company is German but speaks good English and is very helpful.

And no coding at all for me. Literally plug and play to the point I could have one side changed and the other not with everything working as it should.

Excellent… that would remove the need to recode anything. I will make an enquiry and report back http://www.vwaudiforum.co.uk/forum/images/icons/icon14.png

You can get semi dynamic modules here: Audi Tuning Cars - Turn Signal Modules | Semi-Dynamic LED (http://geotechpol.com)
€110 delivered.

[fest0r]

Thanks ;) It’s an option, but I don’t think I would be satisfied with the pseudo dynamic effect. I’m also not sure how it might be viewed by a particularly officious MOT tester. I know the full dynamic cluster isn’t factory fit either, but as it's on newer models it should be less of a problem… if at all.

[Silane]

The dynamic indicators do look great, but no way could I justify paying the price of the conversion. I mean how often do you see your own indicators in operation? Your handing over all that cash so the guy in the car behind you, who don't know and probably never will, gets to looks at pretty indicators, you'll see them once after they're installed and probably never again.

[fest0r]

If you get the hazard function you see them every time you lock/unlock the car ;) You’re also reminded they are there every time you see them on another car... I do agree it’s expensive though. I have seen used facelift tail light sets going for £550 and my old style going for over £380 so it makes it a bit more palatable compared to new parts.

I suppose if we genuinely didn’t care about what others see then we would be driving around in boring boxes with steel wheels and zero bling.

BTW, it seems somebody has accidentally disliked jcdub's helpful post :confused:

I lock and unlock mine unnecessarily just to watch them sweep [emoji3]

Well we see our cars everyday so we want them to be nice to look at, but the indicators you generally don't see working. If I paid for the full conversion I'd definitely be reversing into the drive so I saw them flash when unlocking every morning.
I agree though, seeing them on other cars annoys me too, especially since mine is a 142 (Irish reg) and the 151 is when they changed to dynamic

Just get the semi dynamic modules and save your self a grand! Not as smooth as the facelift ones but a definite improvement over standard setup. Only about 220 euro for the modules.

I thought, the semi dynamic conversion gives you a constant delay between the inner and the outer part of the tail lights, but it seems to me, that the delay is not constant so in some periods the indicators blink in the same time. Am I right, that there is some timing problem, or this is the usual working of this retrofit module?

[buddyboy]

It could very well be the quality of the video capture with the LED light, in person the delay looks constant

Thanks, but the semi dynamic effect is not for me.

I realise the price is a bit of a sticking point for most, but I’m OK with it… especially if a reasonably priced set of used tail lights and selling my own brings the total price down to £500/600.

I got a response from the supplier Mitchy used. He provided the part numbers of the lights (see below) and said the adapters are plug & play. I had asked if any coding/software update had to be done and he says “At maximum one coding will be needed, but that cant be seen in advance.” So that kind of goes against his “our module is completely Plug&Play and should work as it comes” statement :confused:

Mitchy, did you have to use a coding dongle or change anything with VCDS?

I would easily buy a used set of facelift ones but i have yet to see a set anywhere for the a7, probably a lot more available for the a6 since they are sold in larger quantities

[M1tchy]

Nothing at all for me Vcds / coding wise. Was genuinely plug and play.

Worth every penny IMHO :biglaugh:

BTW, do you have any old VCDS scans available? What does the following section on yours look like?

[fest0r]

Apart from your scan having a Subsystem 3/HSP-SG (unique to A7?) and slightly older software it looks the same. If your software is currently at 510 then the active-sound.eu module is definitely more advanced/comprehensive compared to HazzyDayz or Kufatec units which require newer versions for hazard function. I see the semi-dynamic module jcdub kindly linked to mentions “Instructions Included for Coding on Avant Models” so there still might be some extra coding needed on mine.

A local breaker owes me a favour so if he can’t source a set of lights I will grab them from ebay. Thanks for all your advice :fing02:

[M1tchy]

I think my software is now 770, did an update via an SD card from someone on here. However I'd had the lights about a year before I did that with no issues before or after.

If updating the MMI version also updates the central convenience module I might give it a try myself… if the lights don’t work.

[M1tchy]

I'll run another scan at the weekend and see if it did indeed update the module too.

Updating the MMI doesn't update any other modules. Only 5F.

[fest0r]

Thanks Chris… I might give it a miss then. My MMI software has never been updated, but it works perfectly.

Would updating the CCM software be a dealer/specialist procedure only?
