Quick catchup...

Turbo arrived and swapped but still getting some oil in the exhaust when cold.
I'm putting this down to the shallow angle of the oil return, which is still a "cobbled" version.
I'm going to get a proper on made up now and see if that changes anything...

So.. Ive wired the cruise control up.
It turns out the Sharan I stripped had slightly different wiring to the digrams I had.
Turns out the Sharan has 2 more wires to the switch than the T3 original stalks (6 vs 4). A bit of faffing about and it all works.

For future reference...

Black wire is IGN live.
Red is the SET button
Blue is the RESUME button

White connects to the Grey wire from the ECU to tell it that Cruise is ON.
You also need to connect the Black/Green wire that goes to Pin 66 on the ECU to this wire.
I still dont know why, but the ECU needs to see 2 "ON" signals.

Anyway I turned the cruise on with VagCom:
Connect to the OBD port.
Goto "Engine"
Select "Login"
Enter "11463" and click "Do It!"

That should turn it on.

Erm... what else...

Not much really. Van drives really well and pulls really strongly.

Ive reset the rev counter so its closer to the readings given by the ECU, as the rev counter gets its signal from the alternator its not accurate. There is a trim screw on the back of the rev counter under the white sticker to adjust... it'll never be 100% accurate, but its close...

Speaking of VagCom, im not a fan of having the OBD port just dangling, so ive made a bracket to house it under the dash cover:

Ive also tidied up the wiring in the engine bay a little. I'll do this in stages as its really time consuming and tedious :D I could also do with shortening all the wires to the pump really as theres a lot of wire to lose there. For the moment its in and working and once its proved i'll finish off the engine bay.

For now, i'm going to drive it around and see if any issues develop.

Its now officially a TDI!

Slow and steady progress...

Silicone hoses arrived, and Ive now fitted the maf and airbox in the factory locations.
TDI conversions are quite common in a T3 nowadays, but I'm not a fan of the way the engine bays always look. I wanted it to look standard... Battery and Airbox in the standard locations, and as little evidence of the conversion as possible.

Ive also made a wiring loom for the front end wiring... 16 wires in total.
6 for the throttle pedal, 4 for the cruise control, 2 each for clutch and brake switches, and one each for the speed sensor and the immobilser wire.
All sleeved and routed sensibly down the chassis and up into the front through the original wiring grommet behind the headlamp...

Immobilser is mounted in the dashboard.
Ive fitted speed sensor to the speedo that will give the ECU the correct signal... As mine already had cruise control, it had a speed signal unit in the speedo, so its simply a case of removing it, fitting the RJES unit, and connecting the wiring.

Cruise control wiring is connected to the stalks, and pedal switches are wired.
The Sharan brake pedal was a 4 pin switch, as the ECU requires 2 signals from the brake switch....but to simplify things ive used a 2 pin switch on the pedal and given the other signal to the ECU from the brake ligt wiring in the box in the engine bay.
Front end loom connects to the ECU with 3 multi connectors. That way if i need to split the loom for any reason, I dont have to remove the whole lot.

A couple of other bits... one is the Intake Air temp sensor that up until recently was just dangling. Its now fitted into the intake pipework from the chargecooler using a fitting from Mario at M V Engineering.

Ive also blanked the blow off valve on the original JX manifold with a machined plate.

Accelerator pedal has been mounted on the bulkhead, im not particularly happy with this as there is quite a bit of flex in the bulkhead when the pedal is pressed. I'll add a bracket here to strengthen it before I call it "done", but for the time being it works...

Ive discovered that the turbo is passing a lot of oil into the exhaust, so will fit a new replacement.
The AFN with a JX pump seems to produce about 6 bar of oil pressure at idle when cold, which may be something to do with the oil in the turbo, but I figure a new turbo will have the best chance of keeping the oil where it should be.
Currently waiting for the Turbo, but Ive assembled the exhaust and done the maiden voyage... a short drive of about 10 miles. Nothing to report really... It pulls incredibly well, especially at the bottom end of the rev range. Sounds great too! Just smokes a little which I put down to the turbo.

Once the new turbo is here I'll swap it and refit the exhaust and undertrays properly.

Other jobs... mount the ECU properly, wrap up the wiring loom in the engine bay, and sort the cruise control... Then decide where I'm going to take it for a shakedown :)
