Hi,

I have an A3 2.0 TDI from 2004.
I'm trying to retrofit bi-xenon headlights with cornering funcion, but i'm having a lot of problems...
My car had xenon with auto-leveling from factory.
So i bought the bi-xenon headlights, new control module for de AFS and recently (after trying to rewire the original instalation) a set of cables from kufatec to enable AFS...
Instalation was made and recheckedover and over again and the AFS doesn't work and i get an error on the AFS module (55-Xenon Range) about the right headlight J668 (i think the balast) having a problem with power output.
I'll get the error tomorrow and post it here...

Meanwhile if anyone has already made this retrofit, PLEASE give some help as i'm stuck with this for almost one year!!!:faint:

Best regards.

What is the part number of your central elctronics module ie 8P0 907 279 ?

That's the 09 module?
It's the K revision that i already bought to this purpose...
 
Could it be because of the CAN Gateway (1K0907530) module being so old?
 
Have you done any rewiring at all & connected canbus wires to headlights, did you upgrade your levelling module as you cant use the same as the standard xenons, adaptive uses a different module to xenon/bixenon, gateway shouldnt affect it at all if you had existing xenons.

KUfa looms are a pita aswell as there support, personally I wouldnt touch them with a barge pole.

Did you follow the wiring diagram aswell & check pin to pin, add new wires, move pins etc?

It is not plug n play with kufa looms.
 
My advice would be to listen to NHN.

He will get you out of your pickle
 
I seem to recall this member last year starting this.

Yes. I think i've sent you a PM...
On the kufa cables i've done no rewire as they say it's plug-and-play...
I have the AFS module...
 
Yeah & you didnt even check pin to pin with a wiring schematic as yet?

Take my advice, go check your wiring pin to pin as kufa when asked about a technical issue with modules & wiring didnt have a fecking clue where to look or advise, we found out there looms arent all they're cracked up to be a few years ago.

Write it down so its clearer to you.
 
Ah ***** gotta go as missus water just broke, feck me here we go.

Didn't check after installing this new wires...
I'll have to check it out. The cables for the AFS and the Cables for the bi-xenon... To see if anything is wrong regarding +12 connections and earth...

Jesus... Good luck my friend... Go GO GO... :)

Let us know if everything went ok..

I have lights... :)

Don't have auto leveling and no cornering... Bi-xenon works normally, but the pita error on the DIS is fecking anoying... :/

I've noticed one wiring problem, according to the scematics on ELSA PIN 14 on each headlight goes to earth connection. I haven't got that connection done, but in the schematics, inside the headlight PIN 14 is connected to PIN 5 wich is connected to earth...
Do i still need to connec 14 to earth?
One thing strange is that the error is only on the right headlight...
Jesus i'm very near of leting the car go down a cliff.... :/
NHN do you want to come and visit Portugal? I'll pay your flight and you have a place to stay... :D

Best regards.

You need to follow the schematics to the letter, did you rewire the levelling module or just swapped it over?

Hey if you pay me then I'll come to Portugal to check it out, no worries, just remember its not a quick fix, I would remove any adapter looms & put the correct plugs in place of old ones then move wires about, add new ones & solder etc etc to spec of oem fitment, I never use convertor looms.

AS i said i did some rewiring after changing the module...
The only thing i thonk strange is that the wiring is almost the same on both headlights and the error just seems to appear on the right side...
And the only connection that seems to be missing is that PIN 14 not connected to earth...
One more thing on ELSA schematics they say to connect PIN 14 to headlight earth. Can i just connect to an earth point on the cable? PIN 5 and 7 also go to earth...

Regards.

PS: I would gladly receive you here in my house... :cool:
If i cannot do this be sure if you can that i'll pay you the trip and acomodate you...:cool:
 
I see 5 & 14 are connected internally & externally. I'd connect both pins to an earth anyhow just in case.

Is it possible to swap the J688 and J687 and see if the error changes sides? Its not impossible that the J688 module is broken, was it or the light unit 2nd hand? I must confess that i dont have xenon lights myself so i have no personal experience.

Yes i saw the same on ELSA schem... But i'll connect the anyway.
I bought them 2nd hand...
After i recheck the wiring i'll switch the headlights and see if the error continues...

Hi,

Well done the connection on both headlights. Connected PIN 14 from the headlight to PIN 5.
...... No change..... :mad:
Noticed one thing, when i switch ignition ON it takes about 3/4 seconds before the error appears on the DIS...
I'm now thinking that the J668 is really defective, as the connections on both headlights are the same and the error just appears on the right...

One more thing, even with the J668 defective, shouldn't the left one work?

Best regards... Getting fecking tired of this headlight issue...
 
Mate I'm very positive its still wiring issue, did you check all your wiring on central electrics, afs module as thats different, headlights, did you go pin to pin, did you do continuity tests on wires incase of a break, many things to check before handing it to someone else to fix.

Man... I'm fed up with this retrofit...
I'll have to spend some time tearing these cables apart... To the AFS module i think it's all correctThe only lines that go there are the 1 and 2 PINS from each headlight, the wheel sensors, the CAN lines and i think one that goes to +12 and other to earth connection on A-Pilar. If i remember all of these stated are correctly connected...

Forgot to mention... My AFS module is coded for A3 8P Cabrio... Do you think that might somehow mess up things?!
It does not let me code the module i think because of that fault on J668.

Regards
 
You can get odd things with different modules. I fitted the white LED speedo cluster, I then fitted the newest gateway module to see if i got any extra DIS options & the display now came up with a fault with my electric convertable roof! No faults in VAGcom. I Then upgraded the convenience module & it went out without changing anything.

I'd think the correct coding should take even if there is a fault with a module attached to the AFS, it would just report the error of the faulty component?

I also fitted the new cluster. I have one problem. When i activate in 09 the comfort function in the DIS, i can't put the wipers in service position...
I have it disable. I also have a new 46 here, but i tryed to fit it today and ended up (after recoding it) with a boot that would not open...
This mnew module has more Bytes and i can't see them, maybe because my VCDS is 805...

Uh your car is not a facelift, cabrio was facelift so it shouldnt be coded for this car type as coding affects specific pins on the boards themselves.

No not neccessarily Ew, I've had modules that wont code properly when faults are apparent, but also as you stated coding has been accepted even with faults so its hit & miss which is why as above is probably an issue aswell.

Guessing you have a counterfeit cable yes?

So the problem here is almost certain because of the coding... Haven't looked yet, but is the pinout diff from pre-facelift to facelift? I'll have to check it...
Also shouldn't the left side work as there is no fault?
Errrr i'l have to spend more time and money searching for a AFS module correctly coded to an A3 8P...
Regarding the cable... Yes, busted... :rolleyes:

Best regards.

No, I didnt say that mate, the coding is one issue you have which may or may not help the other, you need to make sure its coded correctly for the car you have 1st, if it wont accept the coding then check the module is for the car you have, if so then check coding for other areas on the car as this may be stopping the coding being changed from cabrio, modules do talk to eachother & ask if the coding is ok to be used with eachother as such, so has to match to a degree with info on other modules.

Dont get another module until checked all above as it could simply be as above at fault.

No most likely the system will not work full stop until all systems are shown as functioning 100%.

As I said fix your errors 1st instead of looking or quick fixes ok mate, these mods arent simple jobs, do it right & right 1st time, then saves issues later.

Regarding the cable, if you can afford the mods you're doing which we both know are vastly substantial, then buy the genuine cable out of respect 1st for RT for creating the system to do your work & 2nd so you have full access to all areas, updated module files & updates going forward & dont tell me its too xpensive, your mods are expensive :)

I agree with you 100%... I'll have to buy an original one, because i'm tired of these counterfit sh***i problems...

Regarding the problem itself, i'll have to recheck every coding, every pin of the connection made...
My question remains. Why oh why does the error only appears on the right side as the connections are the same on both sides...

Regards.
 
what all have you rewired? just the lights or have you rewrired the auto leveling & cornering too?

I have just had a quick look, the wiring at the leveling module (J431) is completely different than to standard xenon, even the connections to the axel sensors dont match up.

I would start by writing out the original wiring for the lights, the leveling module & leveling sensors and then the new wiring diagram for lights, cornering, auto level & level sensors & see whats all changed. There is even an extra earth on pin 24 thats not on the original leveling module etc.

All you've stated as been done. First did the rewiring and nothing... Lately as i stated i bought an adapter lom from kufa. I solved the error i had, but another (the one i mentioned) appeared...
24 is connected to earth... :S

If only i could know what pin does this error reffer to...
