T6 OEM LED-headlight retrofit

Flyingspanner said:
I bought my lights from TPS with motors (they don’t come with the LED driver modules 2 req for each headlight as you know if you have read through the thread with 14x fixing screws), for around that price.
Avoid buying the driver modules from eBay UNLESS you can easily send them back as they have had issues with them (even new units failing) so you want some sort of protection to allow exchanging them if they fail.
Replace the front suspension nut and bolt which needs to be removed to fit the sensor bracket as it is torque to yield. Think it was 1st stage 110Nm, second stage 120 degree torque angle but I would need to check ELSA (workshop manual).
I made my own looms on the van, but Pauly’s one will save lots of time.
I did the sensors first and ran the two 3 core 0,5mm looms to the drivers footwell.
The 0.5mm 6 core loom from MX1 left headlight was run down the side of the battery using the existing body clips and into the cabin from a small grommet accessed by easing the carpet and sound deadening out the way. Make a SMALL round hole in the removed grommet (rather than slicing with a blade) and pass the core through, this keeps the grommet tight to the core without splitting.
Use a rod from the cabin to the engine bay (I have a super rod kit, but an open coat hanger would do) tape the 6 core to the rod and ease into the cabin then pass the core to the drivers side footwell keeping it above the pedal box housing (follow large loom right at the top and down behind J519 bracket so it does not get caught in the pedal mechanisms.
MX2 right headlight loom and the front sensor loom follows the original loom around the air filter housing and in through the large rubber gland which needs to be pulled forward to allow cutting two nipples to run the 6 core through one and 3 core sensor loom through the other. Make the cut at 90 degrees to avoid splitting and allowing smells and noise into the cabin. Take time to refit the block correctly into the bulkhead, be patient it will go in. Once you have done a few it is much easier, the first time will be a PITA and you will get frustrated. Use brake cleaner to make it slippy (but dries tight) to ease the process. Same when running cores through grommets.
If you use Pauly’s loom I’m not sure what route he suggests, but I made up mine to look original for the rear and ran the 3 core into the right rear quarter and used an inspection camera to find it as the van I did last weekend was fitted with a conversion with insulation so difficult to get to it in comparison to a panel van. Then ran it up to the factory loom in the roof and along to the drivers A pillar and down to meet the other cores.
You should also remove the range rheostat and fit just the dash one to keep it original.
Look at the images to help picture some of the above.

Cracking addition there @Flyingspanner ! :thumbsup:

Out of interest, where do you buy your boots/bend restrictors for the level senors. I could use a few of those!

I get them from TPS they are listed in the electrical part of ETKA.
I also use butyl cord to seal the rubber to the cable to prevent water ingress. You can just see it at the top.

I see they have changed the part number for the brown original T6 rear sensor plug which is the same black one used on the front sensor now for whatever reason.
 
Hi all,
I'm in the process of collating all the parts necessary for the retrofit – however, my local parts centre has come back to me on some of the components that seem to have multiple variations...

The parts in question are 'Power module for high/low beam' (7PP941571AE) and the 'Headlight range control' (6R0907357C).
They're basically saying that the power module has 6 different part numbers and the range control apparently has 13!

When they say 'different part numbers', they are obviously talking about the 'Zxx' suffix at the end of the main part number (see attached image).
So, with this in mind, does anybody know which 'version' I should be looking for? Or, does it even matter?

@Robert , @Pauly, @Flyingspanner are you guys familiar with these variants/different 'Zxx' suffixes?

Any help is much appreciated!

Thanks

Looks like hes doing a part number search with the digits im guessing you supplied him ?
If you search by model transporters from 2016-2019 come back as 7PP941571 AC Z06

Thanks Pauly – yes, I sent the number Robert listed earlier in this thread 7PP941571 AE so not sure what the difference (if any) 7PP941571 AC has?
 
Need a little help with The coding of the range control module.
It’s a secondhand one and i’m putting in the code given by Robert but I’m being given error codes on selecting’yes’ or ‘no’.
Any ideas?

Hmmm... why then the coding is zeroed. Any history?
Could you please post Advanced ID data from the controller?

If it is second hand then it would already have coding in it and not read 0000000
Do the headlights dive and return to level when you start the van ?
Basic settings will require the security access code

I believe the culprit is the above - the unit is missing so called parameterization file (dataset). That's the root cause for unit showing "not coded" etc. also preventing you to code it.
Probably the unit has been either reflashed (half-way) or is "blank". See below the same from mine:

Unfortunately VCDS is not capable of loading the parameterization file into the unit. VCP or ODIS is needed + the correct parameterization file.

Headlights come on with ignition do not move and turn off when started.
I have security access code from @Robert earlier post On page 16, that worked.

So I’m looking at a new module then?

That's certainly an option. VW dealer should have tools to rectify this, however not all of them necessarily have the expertise.
@Pauly - I found in my notes that VCP probably has a proper dataset file "t6_lwr_6R0907357c.zdc" ;)
