I could be misunderstanding here, but the can-bus gateway is located within the cluster.
so its already wired in and functioning.

The Cluster and ECU is from a 2001.5 jetta Wolfsburg with the AWW engine, its IMMO2.

I've attached pics of the modules connected along with their codes...

the ECU does have a different SW on it ATM, but it Was/IS a 06A906032DL ECU native to the AWW equipped 2001.5 chassis.

Alright, I'll take egg on my face for this one.... But it turns out the ECU was unresponsive turning initial power up this whole time causing the cluster and etc to toss that code.

If i switched on the 12V power supply with the cluster unplugged giving the ECU a moment to start up first, THEN connect the cluster all is swell ( no codes, nothing, happy happy ) 

as great as a discovery as that is, it doesn't help out my TRUE issue.

Would the lack of IMMO pickup coil hinder much in terms of functionality? I'm trying to create a "standalone" bench style flasher for my Maestro suite for my swap, Connect the cluster and etc when flashing or working with the suite is needed... the rest of the time its gone out of the car... Everything works perfectly right until the actual flashing where it calls a "starting communication.... Task Failed! Timed out" error.

If i plug both the ecu and cluster in a mk4 chassis it'll progress without an issue.

The Immo coil is the only thing left i can think of now that this com issue is cleared up.

I power everything same time or with toggle switch to simulate ign. I have coil reader hooked up aswell ( pull lock from column and plugin) im using oem plugs for immo/cluster/ecu not just single wires with connectors.

ECU gets pwr constant and switched(ign)

I would supply pics but the stuff is in storage.

I get what you're saying, and that is the way i have my ECU only bench harnesses working But with this one the ignition was on the same 12V line as the constant 12V feed.
When its implemented in the chassis, It'll be switched accordingly without an issue but on the bench it needs a little extra step. Smiley

I'll have to see if i can grab a coil and wiring to hook it up, I hope... seriously hope that gets this setup working.

Looking at this expensive piece of software that i bought to make things "easier" to tune my car and thinking of all of the headaches so far, It kinda feels like I've payed to been annoyed for a few years now.

Thanks for the offer, but I can make the changes without an issue..

I'm just hoping that the coil is my issue for programming.

The ECU via maestro, it uses the ECU to authenticate the license prior to flashing.

So now there talking without an issue, but it still fails due to a timeout communication to a component, the only thing I can think of is the immo coil error is not allowing the cluster to move forward with a certain mode.

Exactly,  I'll be working on the ECU side and why its not accepting the login after work.

Why do you need to do this on the bench?  I mean, what's the overall achievement?  Just for fun? Smiley  I don't understand when you can just bootmode on the bench and run in the car.  Or just flash in the car.
