Low Line to High Line Mod - can't code the power supply unit

[wmccann]

Hi All,

I have been looking to convert my B6 2003 Cab from Low Line to High line and have had some success:

1) split the cables for the rear lights and put in plugs and sockets, then built looms to the front for the High line using same socket ( allows me to flip quickly between low and high line)

2) built T connectors for the front lights - passing through the relevant wires and bringing the required ones to the power supply unit.

3) Built a T connector for the fog lights - some reason they use a different connector (black) in the passenger A Pillar - wired into the power supply unit.

4) Got a new switch that I wired using a new plug and some spade connectors so using most of the original wiring - new wires bought back to power supply unit - it has Auto lights setting.

5) Connected up the mirror only to find that I do not have a wire for pin 6 (Thanks KUFATEC!!!!) so will have to put in a new wire.

6) Wired up the coming home switch.

7) Wired up the brake switch to the power supply unit.

Anyway, all bulbs work fine - did the tests in VAGCOM and my wiring is spot on.

My problem is that as soon as I switch on the ignition, my dipped beams come on. I though this could be the "daylight running lights" so I looked in VAGCOM and only adaptation 1 and 2 show any items, plus 81

When I try to get the unit to learn my car's VIN it does nothing. Also I can code the unit for the US (000003) and back to rest of the world but when I try to swtich on the light sensor, trailer etc. the value does not change.

Questions:

1) Does anyone know what is going on (could the unit have been locked by the previous owner?
2) Does this unit need a login code, if so what is it?
3) How can I disable Daylight Running lights - I understand it is adaptation channel 8 but I just get an error when I go to this?

The unit itself has a suffix letter of E (8E0 907 279 E)

Any help would be great,

Walter.

I think the first thing, you should do is find out if the,onboard power supply unit j519 is the same for the high line and low line.Otherwise which unit are you trying to adapt?and what code are you using?

Hi Kenny,

No they are different as a result I had to get a new one.

Do you know which lights are on if your car is setup for daylight running lights? Is it the dipped beams + side lights or just the side lights?

I think the unit may be locked out as on Guided fault system it says that if you try to adapt it to the car incorrectly 3 times it locks out for 10 mins and then each time after that it increased by another 10 mins. I might try to leave it in overnight and try to code it the next morning.

My other option is to pick up another second hand one on ebay - they are quite cheap.

Thanks,

Walter.

The output test has nothing to do with which module is fitted,there maybe a difference in the wirng,depending on the equipment of the vehicle
