LED Lights

There is a module available from the dealer and some other options as well I believe.
My 2010 V6tdi with tow package came with one. Ther is a fair bit on the forum re this topic
Good luck,

I'm aware there are issues with Treg's (VW in general I guess) and LED lights being plugged in. Quick reply required if possible on this. My boat trailer requires new submersible lights. I can only locate the LED style. I know these won't work when they connect to the 7-pin plug. What is required to solve this so they will work when the correct signals (brake light, turn and stop) are input? A module I'm guessing from the dealer.

I wired up LED lights on my trailer last weekend and they all work fine with my 2010 TDI, the only thing that does not register is the anti theft feature if the trailer is disconnected while alarm is armed. But the manual points this out - so is expected.

 

just that pesky amber warning light..

I have a mixture of incandescent and led on my box trailer and also my horse float.
They do all work correctly though, tdi-eg complains about check this and check that.. but I just ignore it.

 

Here's what some of your countrymen say

Interesting discussion

You note that these are not 08 owners. I tried every kit from e-trailer including the special module for VW and it didn't work. Maybe a dealer only might. At least for an 08 they never worked, I just gave up.

Guessing your trailer module was coded wrong.. mine was. Finally fixed the problem.

 

The dealer module is not only useless, but most of the dealers I spoke to in Melbourne had no idea what I was talking about. One even queried weather I should tow "such a big caravan with a Touareg". Once I educated him on the difference between a Tiguan and a Touareg, he then tried to tell me it was a caravan issue, not a VW issue.

My advice, go to an Autoelec and get it done right.

 

Try this:

Ok, what's the deal here? Is this gizmo a 7-pin plug-in to the wired socket? Maybe it works on US Tregs, but are our Tregs wired the same as US with indicator signals and night/brake lights? Anyway, I'm wiring up a set of marine LED's to the new boat trailer tomorrow. I'll soon see if the 7 pin causes the MFD to sh1t itself with trailer light warnings. Bet it craps itself and I get crazy flickers at the LED's.

 

You could fit a resistor with each bulb to fool the system into thinking every bulb is drawing the correct current.

 

if you connect the incandescent light together with the leds you wont have any problem. Thats the way i did mine. supposedly the reg give to much power through the hitch and the leds dont need that much.

 

I have two large led backup lights on the horse float with no incandescents in the circuit .. they work just fine .
I have no idea what the towing module thinks other than that it thinks a bit too much for my taste in towing modules..... ..

 

see post #20 - you must have this box in the wiring if the LED's are acting normally.

 

Slurper,
I would go with Mdj's advice and seek out a good auto electrician - one who knows European cars.
I had the same problem with a borrowed trailer with LED lights. The main trailers I tow are fine with incandescent lighting so I did'nt notice any problem. Once I found out my friendly VW tech suggested the auto sparky as he had no faith in VW sorting the problem.
The sparky made up an adaptor the size of a normal pin adaptor with resistors in line to trick the Treg into thinking different. Cost under $100.

 

Yep, I'll see one nearby as well and see how clever he is! Plan B is the BCF/Supercheap Auto plug in light board, which I use mainly as it does not get submerged in salt water. The new boat I picked up is 21' and I'm doing a few mods. Treg tows it like a tractor up hills when I hit the pedal (fuel goes off the wall), but the beast can seriously accelerate up a steep hill with 2T on it's bum. I'm smiling!

 

Gregtay, What was the coding you changed, as I am about to install a genuine Towing Module to replace a "cheapie" after market unit. If you have the details could you share them?

I will need to go out and look this weekend... but I believe i changed it from whatever it was to 000001 or something like that. Solved the issue.

 

Oilslurper, it won't work. Tried that very part from etrailer 2 years ago on the 08 V6 and it just strobed.

oK, THEN HOW ABOUT THIS :

LED Trailer Adaptor Module European and UK - 4x4 Accessories - LED Trailer Adaptor Modules - 4wd Recovery Gear | 4wd Accessories | 4wd Equipment and Camping Gear Australia | Axe and Shovel Holder | Combo Shovel | Synthetic Winch Rope | Camping Lights

 

It's mostly conforming to Euro specs. Europe is migrating to 12 pole connectors (must be the retro rockets and dilithium load stabilizers that require it). I'm not sure what the Aussie wiring is like - probably closer to Europe than to us. It might work. But by the time you pay for shipping... I managed to return my 3 variants back to e-trailer and called it a day. Now I just open the hatch and have one of my dogs howl from the right or left

Ah so, not so dim after talking to VAG HQ in Sydney. The part required is:

VGA 055 204 LOAD

the hip pocket damage is $214.14...........It'll be connected this arvo!

 

5 mins of my labour and it works. Zip tied to the trailer with 7-pin flats both ends. Throw some money at OEM box and it works. And the Treg and trailer lived happily ever after. The end.

 

Have any Aussie guys tried this from the US? A bit cheaper than the VW 'Load' module.

Ours are wired like this down under - not sure they're the same pin configuration for that adapter:

I got one of those load sensors today from VW, plugged it in works no problems at all. Well actually there was one problem the price tag, they wanted $250 so I moaned and grizelled at abit and they dropped to $210.
Thanks for the heads up Oilslurper.
Now if I could only find someone to fix my indercators coming on with my brake lights I would be happy. Seems none of the VW dealers in Brisbane can do it... I even paid $132 to one dealer to tell me that they can't fix it.

Ok, that ain't right. I reckon the 7-pin is wired wrong. There's no way that the indicators should flash with the brake light. $132 to the dealer to stuff it up, then you get them to do it right. It's basic stuff.:chainsaw:

 

The problem is in the trailer modual, it's set to european and no one can change it to australia. The shop that charged me $132 told me I had a non genuine towbar and wiring harness, so they couldn't fix it and charged me for their time. It's a Westfalia brand which is a standard VW item. The other shop said they didn't have the right plug to test it , so they wern't going to change it. I rang a couple of other dealers and had no luck either, so I just put up with it and hope I don't get pulled over by a cop having a bad day.

What do you mean by non-genuine towbar and wiring harness? Is the standard a goose neck and you have a 2in receiver, and was the wiring spliced in or did you use the control module? Just wondering. Thanks

 

8 years on and people are still haven't issues with trailer wiring, starting to make me things my 12 months of misdiagnosis a bit of a walk in park.

 

There's always a way............you just gotta find it! After all, it's just copper wires and electons.

 

Methinks Phillz is more worried abut the copper in a blue uniform than the copper with electrons

Seriously though I agree there must be a way. So I think a way forward is to start by isolating where the problem is Phillz.
Have you had this happen with any other trailers? If not try another one and if the problem is still there then likely it is in the car. If not then it may be a problem in the trailer - see shootsie's suggestions as they would be where I would start.
Alternatively try the trailer in another treg - you are in Brisbane, perhaps go for the upcoming gettogether there and using your powers of persuasion try with someone else treg, oh and have a look at their set ups to look for any differences to yours.
Check if there is a problem with non led lights. If not then there is a load issue and you may not have solved all the problem with the adaptor. If it persists then you know you have a wiring issue which is independant of the led light issue so you will need to start tracking that one down step by step.

Looks like it might be a slow process but there has to be an answer as oilslurper said. :confused2:
First step try to isolate where the problem is, car or trailer. Cheapest way to do that is get another treg and trailer with led lights and swap over. if problem follows trailer, then trailer it is. If problem follows car then you know where to start.
Hope this helps

 

It is a genuine towbar, harness & module. It had a wesfalia sticker on the module not VW, so they just presumed it was non genuine. Later research found that westfalia supply VW,Audi and Porshe with the electric side of things. It has a goose neck and 2in receiver and control module fitted by the VW dealer before pickup when new.
