Retrofit B9.5 headlights matrix & tailights to B9

[MugurMarius]

Hello,

I would like the following:

1) put matrix headlights from B9.5
2) put tailights from B9.5
3) Engine change

For point 1 & 2, what pieces I need (besides the headlights/tailights) and if it can be achieved easily.

For point 3, I need to change my engine, I just replace without updating the cluster mileage (it's recommended to update the mileage to the new engine or just leave it like it was?). Do I need to update the ECU if I swap engine? It's the same engine (cwgd)


Thank you and sorry if I opened in the wrong thread.

Alex from Europrice can get you sorted on the taillights. He has a plug and play package. As for the headlights, no one has confirmed if the B9.5 headlights will fit on a B9 car. There may also be coding and wiring issues. If you find out please let us know. I'm sure a few people would be interested.

So far I do not believe anyone has attempted the B9.5 headlights in a B9 model. I believe the issue you may find is body work will need to be changed as well, bumper, grille, etc. Then you have the challenge of getting the current Central Elec module to understand how to run them properly. With that said you can fit the B9 matrix lights:

As for the taillights, the B9.5 taillights do fit the B9 body and there are full packages here:

Taillight Package | A5, S5, RS5 Post-Facelift LED (Highline) <-Click for More Information

There is a bit of wiring work that is needed and is recommended for installers to have experience in this type of work. Once installed, parameters set with VCP and proper coding done you get the full functionality, dual rear fog light and the animations like this:



As for changing out a motor, I don't believe anything change in a massive way between the B9 and B9.5. Same engine code and the pre-facelift long block supersedes to the post-facelift part number. I see no changes in the turbo, intercooler, etc. Probably mild revisions along the way but should be a direct swap.

I've seen it mentioned in a few reviews of the B9.5 that the only thing Audi changed in the motor is some ECU programming to help fuel efficiency at lower speeds. However, I haven't seen it mentioned in any promotional material from Audi on the B9.5 so I'm assuming it's extremely minor.

Hi MARIUS,

I CAN HELP YOU WHITH THE HEADLIGHTS AND TAILIGHTS B9.5

THANKS

hi alex,

the audi a5 b9,5 headligts will fit in b9 prefacelift.just need to change bcm2 wire and coding.

Sounds like the post-facelift headlights will physically fit in the B9 pre-facelift bumpers?

As for the need for the BCM2, not sure why that would be needed for headlights as they are controlled by the BCM1 (Central Elec). Did you mean to say a new Central Elec [09] module is needed to run the post-facelift headlights?

Cheers,

[Emillio2007]

HI ALEX,

I HAVE THE WIRE DIAGRAM,CODING ETC FOR THE FRONT HEADLIGHTS TO BE RETROFITED. I M MORE THAN HAPPY TO HELP YOU.

EMILIO

THE HEADLIGHTS WILL FIT IN THE PREFACELIFT BUMPER ,YOU NEED TO CHANGE ONLY THE HEADLIGHTS BRACKETS ,THE FRONT BONET IT S THE SAME.

[MugurMarius]

Hi Emilio,

Can you please share the diagrams?

Thank you

I'm wondering how the headlight swap is possible because the lower part of the headlight is different shape/dimension. There should be a gap between the headlight and the bumber if you retrofit facelift headlights

It’s just the way the rendering looks. In reality the pre and post facelift headlights are the identical size and shape. Since VAG is focused on cost reduction since diesel-gate it makes sense that they would want to minimize the cost of a facelift.

[Emillio2007]

At least someone done the homework properly. Because many guys on this forum they don't know what they're talking about...

Fenders and bonnet are the same in B9 and B9.5 but the bumber has changed, so changing the shape of the headlight regarding the part next to the bumber shouldn't add that much to the cost since the headlight has changed anyways

Actually when the facelift came out and I was thinking of this update I even went to a showroom with a tape measure to check the possible fit of facelift headlights
There's approximately 1,5" difference in lenght measured from lateral lower corner of the headlight to the kink next to the grille (see image)

@ Emillio2007: Could you post some close up pics of the headlights and the bumber?

Yeah but those little costs add up when you're talking about hundreds of thousands of vehicles and Audi has to pay for all that up front and then recover the money after the vehicles are sold.

Well aware of the cost structure and scale of it, but I still wonder how much there is to spare by retaining the external shape of the headlight as the product itself is different. The frame has most likely changed since it houses different lighting technology. And in A4/S4/RS4 B9 facelift the shape did obviously change.

That might be the case. But still, please post some close up pics of the updated headlights to prove also the measurement I did incompetent

[Exotic]

This is amazing! I've ordered the A5 with Matrix LED's. Is it possible to activate the animations without the laser lights?

[Emillio2007]

Yes mate can be done the matrix!

Hello Everybody

[Emillio2007]

HI MATE,

DID YOU MANAGE TO DO THE CODING FOR AUDI B9.5 REAR LIGHTS?

[RomaSTI]

Hi guys! I installed on A4 B9 headlights from A4 B9.5, everything works. Only there was a problem with parktronic. The front bumper with sensors and BCM J519 set from restyling, and the rear sensors are original.
What could be the problem?

[andrelis398]

hello Audi enthusiasts, looking who can help to retrofit matrix headlights on my audi a5 2019, lights is from 2020 model. i have new bumper, lights, new bcl from fl model. did wiring, but now need to correct programing have odis, vcp.

[Stakis]

As i now understand your experience is priceless. Front bonnet and wings are the same. Headlights, brackets and bumpers are different, but headlights fit on pre fl model an bumper.

Maybe you know about sportback, coupe and convertible fitment of front and rear end parts? Front is the same on all model shapes?

Rear i guess should be the same coupe and convertible? I mean trunk lid and rear bumper? What about tail lights? The same shape and size on all body shapes?

Thank you for help!!

[Stakis]

Sorry, cant edit messages. I was talking about Emillio2007 :)

HI MATE,

Hi. I’m have a trouble to install facelift tail lights to my A5 B9 sportsback. I know it needs wiring work but I can’t figure out which should be connected with which. I’m doing this because the yellow turn signal and break lights don’t work at all. The inner lights works as well but this outer lights are killing me.

There are 4 wires:

Left
Brown (socket number 1)
Green & Black (socket number 2)
Blue & Gray (socket number 3)
Gray (socket number 5)
Socket 4,6 are closed.

Right
Brown (socket number 1)
Green & Black (socket number 2)
Gray & Black (socket number 3)
Gray & Black (socket number 5)
Socket 4,6 are closed.

The new tail lights has 6 pin socket and the seller told me I should connect with
Socket number 1. Negative Electrode
Socket number 2. Dat Timing Lamp
Socket number 3. Break Light
Socket number 4. Turn Signal Lamp

The problem is socket number 4 is closed and I did all the possible variation but it still doesn’t work properly.
help me please.

They won't work properly until you flash the BCM with the right software for the new taillights. Flash first, then troubleshoot wiring.

[ultradmp]

I see. but then how can I flash BCM? What do I need? I only have OBD11. can you explain me the detail? I’m a newbie tho

Hello everyone! I try to retrofit the taillight on my S5 2018 Convertible but the XML files for ODIS missing to parameterize the Confort Module.
Someone have this files please?

This looks like an old post. I wanted to see if anyone would respond here before making a new thread.

Has anyone successfully installed B9.5 matrix headlights in a B9 series S5? Comparing wire schematics between the two, they are a bit different. The newer headlights look to have less wires. Two power wires a ground and two communication wires. Is this a simple repining the plug and not using the extra wires left over? Can I use an activation tool used to activate the matrix function to add necessary coding, or will this need to be done through VCDS?

I understand the B9 matrix light is more plug and play. Ive installed a post facelift bumper kit and the newer b9.5 lights would just make my build perfect. I'm capable with the electrical and the install part of this job if its possible. I'm definitely going to need help on the programing part. I have the VCDS scanner tool, but little experience using it.

Thanks in advance..

The headlights are a different shape so you'll also need a new hood. Was it an OEM post facelift bumper or an aftermarket one designed to fit onto a pre-facelift car? If it was an aftermarket one, it would have been designed for B9 headlights and not B9.5 headlights so you would need a genuine OEM B9.5 bumper for the B9.5 headlights to fit.

[jason.pearson]

The part number (8W6823029) for the hood from the donor 2022 RS5 is the same part number for my 2018 S5. They don’t offer a different hood for the b9.5 cars with matrix lights…

When looking at aftermarket light options, the year ranges are from 2018-2024. There are wire mods depending on the year but instal info is limited. The housings appears to be identical. I’ve yet to take the bumper apart to start this job until get more info on whether it can be done or not.

Has anyone physically attempted this project with or without success?

Yes, the people who offer conversion kits offer a B9 -> B9.5 taillight kit but no B9 -> B9.5 headlight kit as they said they've measured the headlights and they are a different shape. A couple of people also tried test fitting them and posted photos showing that the B9.5 headlights didn't line up with the B9 body.

[jason.pearson]

Bimmer plug offers the same HEADLIGHT and part number upgrade for 2017-2024, but requires wire modifications because their plugs are EU and not US models.

I’m looking for info on the wire and coding modifications needed. The models equipped with matrix lighting don’t use a different hood like you stated previously. With them using same hoods and fenders, and aftermarket’s sellers listing fitment ranges 2017-2024, I can only imagine the lights are the same size. Where can I find these pictures that show the headlights test fitter or another post on the subject explaining how they didn’t fit?

Everything I researched says they are the same. All headlights on eBay and aftermarket sellers list these lights as fitting years 2017- to current with only wire and coding mods.

I’m looking for replay from someone who actually has tried this vs someone who read it can’t be done.

I’ve found several post of this job being done successfully but can’t find info on the wire or coding modifications needed. All the post I can find are years old. I was hoping this forum had more members that did after market mods.
