Does anyone happen to know the codes for US spec taillights? I used the codes OP mentioned however like @jcutchall mentioned the brake lights and signals were reversed. I didn't spend a lot of time trying to figure patterns in the codes. I haven't decided whether to get euro-spec taillights at this time but would like to change the way current taillights work.

Thanks.

Sir,

Think this link will answer your question...if not just let me know

Thanks Dan! Finally got around to it and the programming did work.

Guys, need some help here. I received my ROW (amber) tail lights, but prior to installing, I coded with VCDS to ensure it would work with my US spec lights prior to installing, no issues at all.

With the EU/ROW tail lights, I just popped open the little connectors, took out the pins and swapped the connectors over. Plugged in the lights, and the behavior was reversed. So, I figured there must be something in the lights that need to be coded. So, I used VCDS, recoded back to US, then back to the changes mentioned in the thread(s), using TEST before SAVE, still not working.

Any thoughts/suggestions?

You wire the lights correctly when you swapped your connectors?

I checked that again too. I took pics of each connector before as a guide, and put them back in the same order. I can check again to be sure. I've attached the pic of the euro connector (black) and the us connector (tan) for reference.

Jay,
I am out of town on business...will take a pic of mine as soon as I get home to compare.

Ok... Not a problem. I'm curious though, from a coding perspective, do we know what each bit is in each of those channels? If not, is there a way to find out?

Jay,

Try this...is what I did to make my wife's car work.

Channel--- Code
195--------- 5
196--------- 37
197--------- 12
198--------- 44

Not sure if this will fix your problem, but worth a try....just make sure you make good notes, encase it doesn't.

Well, I did some troubleshooting today. I used my digital multimeter and checked the pins for blinker and brake lights. I swapped the pins for each and it's working fine now. I must have inadvertently swapped the pins, or, the pins on the ROW and US tail lights are in fact swapped. Dunno, but it's working now, so yay. 8-)

Has anyone said anything about the brightness difference between the full red LED and the single row of amber LEDs?
