2010 Jetta LED Tail Coding

[digitalextremes]

My present cecm is 5K0 937 086 E on a 10/03 built jetta wolfsburg whick gives me a bulb out error with all possible codes. The replacement hight line version for my vehicle is 5K0 937 087 F Z6B. I just don't know if this version would work. I haven't found any test results for this newer cecm.

what does this mean VW369 Halogen VW369 RdW TFL_0 ROM 14 VW369 VW369 halogen RdW TFL_0 ROM 14

I have a working highline CECM with LED Tails & rear fog. Unfortunately I have very minimal knowledge about electronics but I think we can try to solve this problem by 1) identifying the root cause and 2 determining what needs to be changed in order to bridge the gap.

What I can do is use 0E, I can take some readings at the pins in the trunk and record which wire has how much current & voltage during a specific event such asking using parking signal, brake, etc. and compare notes with someone else who is getting errors with 0E, I think may be able to identify the root cause this way.

Do I have any volunteers who are willing to spend some time and do this? I can create the use cases (excel file with what info needs to be captured)

kiekar: Are you able to use a multimeter and take some readings?

Presently my vehicle is not setup for rear fogs. I’m using 1F for byte 18. One thing I did notice when testing codes for byte 18 is that after clearing the faults and setting byte 18 to 1F, I would not receive any bulb out warning (no faults). The lights functioned properly for turn signals and brake lights. This condition would work indefinitely but as soon I turned the light switch to the on position, I would receive the bulb out warning and the two faults for address 09 Left and Right Tail Light.

digitalextremes: I don’t have a multimeter but my bother does. I will see him this weekend and try to take some readings.

Hi Amd,

I have a 2010 vw jetta tdi. I brought the cherry red led tail light set from ecs. I have a vcds. If i keep the inner stock tail light (reflective) and just replace the outer led tail light. What do i need to do? Can you tell step by step? I know i have to do pin swaps at the tail light. If that does not work, what do i need to do to make it work?

[phil123]

it works, but with the bulb light on the dash.

and if you put LED tails on the outside and stock on the inside IMO it will look like gar-bah-age

[Bigeye]

What do i need to do to get no bulb light on the dash? Do i need euro switch?

to date i dont think there is a way. pull hte bulb on the cluster? lol.

[AMD IS THE BEST]

I have the LED tails, with rear fog, added front fogs and OEM bi-xenon's and do NOT have a bulb out indication. I did upgrade my CECM, so that might be what took care of the bulb out indication. I did all the mods at once, so I can't say for sure.

[phil123]

Sorry, yes, if you have the rear fog you shouldnt even have to upgrade the CECM, just code it like the european jetta's are.

For those of you without the rear fog, my statement still stands.

You do need to upgrade the CECM for front fog's and OEM bi-xenons though.

Is this cecm going to work if i install the cherry red led tail light with rear fog only from ecs tuning? No front fog lights. So all i need is a rear fog light wiring kit? Is that correct? Thank you.

[Bigeye]

Does any body know if this 5K0937087C sold by ecs tuning http://www.ecstuning.com/Search/5k0937087/ES401545/ is the same as the one amd is the be best use for his upgrade cecm whick is 5K0-937-087-Z0X. The cecm sold by ecs doen't not have Z0X at the end. Not sure if that is low-line or high-line.

[Bigeye]

Amd, how much did you pay for you cecm 5K0-937-087-C-Z0X? Where did you buy it?

That's the CECM that my car had very similar coding to yours. I can't say for sure that the LED tails will or will not work with the low line CECM but from what I understand, you will get a bulb out warning (COULD BE WRONG). I had already upgraded my CECM prior to installing the ECS LED tail lights.

I'd contact them directly to make sure that it's the Z0X model. I can confirm that my car works 100% with the LED tails, rear fog, front fogs and OEM bi-xenons WITHOUT and bulb out indication on the cluster (and no errors).

Amd, how much did you pay for you cecm 5K0-937-087-C-Z0X? Where did you buy it?

I paid something like $258 if I remember correctly and I got it from Paul at Keffer VW (user on here). However, I have been asked by another member on here to perform the same upgrade for his TDI cup and the C-Z0X can't be obtained by Keffer anymore and I can't seem to locate one anywhere. If ECS's is the Z.., GET IT! Also, just because mine worked I still can't guarantee yours will too...

Many people can get the car to work with the euro led tails WITH THE REAR FOG. Its the people that do not have the rear fog that are having issues with the bulb light on the cluster being on.

Hello,

I just recently swapped my BCM from 5K0 937 086 E midline to a highline 5K0 937 087 C Z0X highline on my 2010 Wolfsburg. All I can say is that it works wonderfully. I'm using HEX 56 for byte 18 as I am not using Fogs on my vehicle. I have both reverse lights working and do not have a bulb out warning on my dash. Initially I used HEX 55 but my inner LED light was not functioning when the light switch was in the on position.

Thats not totally true, I've had my made in mexico led tails without rear fog for 3 years now and never got bulb out warning. Now I have seen and programmed hella china made led tails and those have alot of issues, lens turning yellow after a period of time, leds burning out, bulb out on the cluster. I do understand that the hella china made are much cheaper in price $200 then the made in mexico ones $450 but its worth every penny in quality and overall function.

I dont see a 2010 Jetta in your list of cars, so i will venture you are talking about your MK5 with MK5 electronics. The 2010's are a bit different since they are basically MK6 Golf/GTI's with the MK5 body.

This thread is specifically 2010 JETTA coding, which is what we are having the issue with.

For what its worth, the tails i was working on were the mexico, expensive ones.

Where did you buy your highline cecm 5k0-937-087-c-z0x?

[kiekar]

Where did you buy your highline cecm 5k0-937-087-c-z0x?

I contacted 1stVWParts at http://1stvwparts.com/, located in Washington State and asked them for the Z0X part number no substitutes and they where able to locate one at the VW depot in Jacksonville Florida. I was also able to locate the part in Germany but the price was more expensive. They where asking 299 euros including shipping but you have to also consider the cost of duties and taxes. If your interested to contact them just PM me and I'll send you the email address.

100% will not work if you car is a 2010 with all MK6 electronics.

[digitalextremes]

Agreed with AMD

Mk6 electrical cecm don't start with 3C, 3C is for mk5

[Bigeye]

I did swapped the wires at the rear led lights. I did the following:

Colors for the 2010 Jetta Tdi after the European LED Tail light Mod. RIGHT SIDE (passenger) 1. Brown 2. Grey/Red 3.Green/Black 4.Purple/Black LEFT SIDE (Drivers) 1. Brown 2.Grey/Black 3. Purple/Black 4. Red/Black.

At the cecm, I removed wire from pin C47(gold connector) and placed electrical tape over terminal and set it aside. I moved A28(black connector) to C47. A28 remain empty. I added rear fog light trigger from the euro switch to pin A17 at cecm.

I did full scan and change byte 18 to 05. All lights worked. Brakes are red.

The problem is a get a bulb icon light on the dash and says rear parking lights are out and left fog light are out but they are not out. I also get 2 fault codes at address 09 cent. elect. How do i make the bulb icon light on the dash and the fault codes to disappear?

If all lights are working as expected but you are just getting an error or bulb out then you should try different values for byte 18, try what I have with my rear fog on the 2010: 0E (zero E), for some people 1F works

There is a thread about it, do a search. If you are just unlucky then you have the cecm that will give you the error no matter what

I don't have the same cecm that your have, mine is 5k0 937 087 c zox

[Bigeye]

I got same result of 05 when using 0E at byte 18. Results from 1F are rear fog light does not work and bulb out light on dash and 3 fault codes.

[teerak2uk]

maybe place a resistor to the same value the bulb would normally be this should fix the bulb fail warning error your getting

http://www.ebay.co.uk/itm/3207743917...84.m1438.l2649

value normally depends on the rating of the original bulb and now how many led`s are replacing that bulb

How do you install 2 x 25w 25ohm CANBUS LED Car bulb Load Resistors leds?

you use 1 per bulb that is causing error and it is wired so one end is one the pos feed for the bulb and the other end goes on the neg wire as all it does is give the same current draw as the o/e bulb would

Does any body know if this 5K0937087C sold by ecs tuning http://www.ecstuning.com/Search/5k0937087/ES401545/ is the same as the one amd is the be best use for his upgrade cecm whick is 5K0-937-087-Z0X. The cecm sold by ecs doen't not have Z0X at the end. Not sure if that is low-line or high-line.

Don't buy this cecm unless ECS Tuning tells you what the color index is at the end, it is either zox (auto tranny) or zov (manual)

I know cecms are non returnable at the dealer, I am assuming ECS tuning follows same policy

My car built 09/09 has no error messages using the zox version of this cecm

LED tails don't require highline cecm, lowline should work fine. I only needed the highline cecm for HIDs and front fogs.

For me it was a direct replacement for my lowline cecm 5K0 937 084 A
