Manual. I'm not sure it's all communicating though. Shouldn't the autoscan have contained more data? And why VCDS communicate with the different components (fuel pump...)? I plan on checking the CAN system and finding the missing starter wire. I still think there's a communication issue somewhere. I'll have more time to play with it this afternoon so I can post a more accurate description of what's going on.

On Beetle there is a clutch switch that will not allow car to crank.
Maybe this is a problem?
Did you try go direct in each module like I suggest to you?
Forgot auto scan for now.

I have the clutch pressed in. Taped in actually. I didn't have time after I autoscanned to do much. I tried to go in the fuel pump, air bag module and ABS. The air bag and ABS aren't there so it obviously grayed everything out. The fuel pump it said had too many communication errors to continue. I'm at work now but I'll try again when I get home. I left the battery charging so hopefully it'll have more juice when I get there.
I checked 109 and it's good. I checked the plugs on the others and no wires are exposed or even remotely looked damaged. All the pins are good. I'm having a hard time figuring out how to get to the wires when they are plugged in to check them.
I also can't find that stupid starter wire. Supposed to be red with a black stripe and it's a single wire.

There is no Fuel pump module. So that controller will never connect.
You have :
Engine-01
ABS-03 ( if you use it for beetle)
Air BAg-15 ( if you use it for beetle)
Instruments-17
Can Gateway-19
Cental Convice -46( for electronic windows) 35 ( For manual windows)
Radio-56 ( if you use it for beetle)

Engine leads me to an error screen. Says controller uses unknown protocol. Protocol keyword: $FDEB. Google led me nowhere on that one.
Instruments also yields an error screen but the keyword is $FD8A.
CAN gateway also an error...$F9EB.
Immobilizer=$F1CA.
And this is as far as I got. I promised the wife dinner and a movie tonight since she's let me be in the shop pretty much all the time unless I'm at work or sleeping. I'll pick back up first thing in the morning.

Seems I read you only have 1 wire connected to the starter?.......... should be two!
There should be the big positive wire that goes on the bolt on the solenoid with a nut holding it. The other wire just plugs onto the solenoid.
Surely you got those..... just a reminder!

The small wire is the one I can't find. Supposed to be red with a black tracer but I can't for the life of me locate it. I have no idea what other plugs it should be near and it's a whole lotta harness to check.
I'm also convinced there's a communication error somewhere in the system. I've got to get at the wires on the back of the cluster plugs and ECM plugs so I can test them. Something is no bueno for sure.
edit: I just thought of something, is it possible I somehow damaged the circuitry in the gauge cluster itself during the fabrication process or is it pretty robust? And could that be my problem? I don't remember ever dropping it but it could have happened.
Results in red.
Edited my findings on pin 1 & 2. Edited finding for the cluster to DLC wire (grey/white).
Since everything checks out ok, now what?

Now you are getting somewhere, you can at least communicate. Now to find out why the engine controller is not coming alive.
I couldn't tell you. I think it's alive but for some reason VCDS won't see it. That would explain why I keep getting the unknown protocol error.
I do have some exciting news though. It runs.

I got tired of chasing my tail with vcds and gave up on finding that stupid red and black wired so I made a jumper from the starter relay to the starter. It hasn't run in 2 years and it fired first crank. Scared the bejesus out of me.

Form Coolant temp sensor , the one located on engine. not on radiator.

There is a dual temp sensor in the water outlet off the end of the head behind/under the vacuum pump. One part feeds the cluster, the other the ECU.
Fan low speed is controlled by the switch in the rad or Fan Control Module when AC is on. High speed is from the Fan Control Module with input from the rad switch.

Exactly what I needed to know. I'm using a stock fan but not a stock radiator so I wanted to be sure I wasn't going to have to control it with an aftermarket controller. Whew!
Thanks for all the help guys.
