Aussie work Van

[MWMRacing]

Got the van out of the workshop for the first time over the weekend, drove out under its own power without issue, few errors to sort still on the ABS side, but otherwise almost everything else error wise is sorted.

I want to take it for a proper test drive but didn't want to give it a decent run till the bay wiring was wrapped, which on one hand is good because I won't damage anything on the other if I have an issue I need to solve will be tricky, but given the errors I have I believe the wiring is done.

Thankfully after wrapping I didn't generate any new issues, so that was a positive.

After getting it onto all 4 wheels it needs some lowering, but main focus is getting it on the road first then the modifications can begin!

Slowed down progress wise over the last few weeks with a couple of race meets I was prepping for in one of the Mini Racecars- but focused on getting some done in the small allotments of time available- I popped the dash back in, and some of the centre console bits and bobs bolting all the modules into their correct spots so I can take it for a proper drive without things flying all over the place.

I spent some time today also wrapping the washer bottle harness as foe wherever reason it had been stripped back and the bottle missing, so that will be a job to pop it back in before the bumper goes back on.

I need to also get a better head unit for the van as this stock one is apalling, and find out what speakers I can use to better the audio quality throughout the whole van.

Also discovered that the slip ring wasn't registering properly so moved the one from my jetta which I've had sitting in the yard, so when I fire it up next I'll give that a whirl

This has been an amazing read! Thank you for adding so many photos!

Would love to know your process behind wiring and how you went about knowing where everything goes

Glad you have enjoyed the read- always like using pictures to demonstrate a bit of the story with any posts i do anywhere.

So the methodology i used towards the wiring was- i started out removing the engines and determining where the TFSI plugged back into the car on the donor EOS to then link back in- IE T94 on the ECU from the body and several other wiring connection points in the right hand side of the engine bay- from there because i knew that T94 also existed on the diesel caddy as a connector, i pulled all the wiring diagrams for both the caddy and the EOS, and proceeded to create a pinout in Excel, and laid the T94 out next to eachother in the spreadsheet, and then created a third table with conversion- saying the old caddy pin on T94 moves to where for the EOS TFSI ecu- this assisted a lot as a starting point but i quickly lost motivation just repinning the ecu. I naively thought that "Surely it will just be T94" but it wasnt the case, So to get the project moving again i decided to install the Engine and gearbox into the caddy to give me something tangible progress wise to see, and then determine which connectors were in the EOS that werent in the caddy and started stripping the Loom segments as pigtails out of the EOS and pinning them in as necessary using the wiring diagrams to create diagrams on the pins usage, where it needs to go and what pin on the connector its going to, depinning where i could, splicing extra wire in where needed and cutting where necessary.

Eventually i reached close to the end of what seemed like endless wiring- when i came into this project some people said that there was several hundred hours in wiring alone for the first time round, and i can verify that, but as a project i wouldnt change doing it myself at all, ive learnt a lot, and the best thing that i did was simply go- one pin at a time, and it makes it a heck of a lot easier to manage, as when you look at the project as an overall whole on the wiring side it is extremely daunting.

I slowly got faster with each pigtail i ran, with the last couple only taking me 30-40 minutes each to put in, but more time going into research to ensure that where i was reinstalling them was going to work for the caddy itself, again the diagrams and my spreadsheet being king- and for this build in future troubleshooting if theres any issues allows me to troubleshoot from what i did exactly as i tried to take notes on how i ran specific wires and where they are physically run in the loom/cabin/engine bay for ease of troubleshooting later.

Currently where i am up to is that i no longer have any errors related to the engine swap itself thankfully, i only have a few lights related to the ABS which is the usual tricky bit to sort out, so ill be working on that over the next little while to ensure that i can get it error free before it goes off to Engineering here in New South Wales ahead of registration- goal is to have it on the road in February with plenty more mods to take place after the registration period such as custom exhaust with catted downpipe, facelift front end, lowering springs and axle flip, rear interior fitout, and carpet in the front cabin area, plus any other little mods i find along the way.

Well, its taken a while but there's been a lot of progress in the small areas, it's taken a while with a bit of beating my head against the wall, but we are nearly there!

Over the last few weeks I've slowly but surely been getting more and more of the old wrap off the van, the paintwork underneath is pristine which has been fantastic.

The hurdle ive been waiting to try and overcome is the errors with the ABS/ESP- all were pointing towards a steering angle sensor issue, so I spent a few hours today swapping different combinations of swcm, slip ring, angle sensor and calibration methods, and eventually discovered all that was the issue in the first instance was the security unlock code needed to be different, once done all errors were clear from the dash for the first time ever!

I also discovered a code about not reaching boost pressure, which thanks to a tip off from a mate said the divertors always go bad, so swapped one off my jetta which we stripped last weekend- the caddys one was indeed toast, so after replacement i took it for it's first drive, and what an awesome bit of kit now it's working properly!

Next I unfortunatelt have some research to do as I have a couple of Transient codes which everything is working fine but it's periodically losing communication with items from the ABS, so will be diving into that now
