Hi Everyone -

First post here with a doosey...'06 V10 Treg, trying to get it back on the road after dropping the engine myself to swap both turbos, EGR sensors, and Tandem Pump...also took the opportunity to replace the freewheel and generator coupling.

The turbos were rebuilt by XSBoost Technologies who did a great job. The work they completed is as follows:
Right Bank Turbo:
- Rebuild bearing housing
- Replace gear and motor in VGT actuator
- Replace board in VGT actuator - Board would not respond to turboclinic tester

Left Bank Turbo:
- Rebuild Bearing Housing
- Replace gear and motor in VGT actuator
- Board for actuator was in good condition and was reused


I reassembled everything and through VCDS am getting the following errors between ECM1 and ECM2:

At that point I took the treg to the dealer to see what they could do with it. They inspected the wiring between the ECM and driver's side actuator (Actuator 2). They found the wiring to be correct and recommended I replace the actuator. Vehicle runs and drives fine, but because of the fault is in a sort of limp mode and will not provide enough fueling to generate any boost.

So I went home, put the lump up on the lift and checked the wiring for the passenger's side actuator. I get +12V between pins 1 and 2 per the wiring diagram and 60 ohms between CANH/CANL on pins 3 and 5 of the actuator connector with the ECM plugged in. Continuity checks out between each of the pins on the actuator and the corresponding pins on the ECM plugs.

started running output tests through VCDS...which is where the fun started...

Both actuators plugged in:
Fault Codes:
- ECM1: No fault Codes
- ECM2: Fault Code for Turbo Controller 2, missing messages
Output Tests
- ECM1: Boost Control Output Test runs both left and right bank actuators
- ECM2: Boost Control output test runs neither actuator

Both actuators unplugged:
Fault Codes:
- ECM1: Fault Code for Turbo Controller 2, missing messages
- ECM2: Fault Code for Turbo Controller 2, missing messages
Output Tests
- ECM1: Nothing
- ECM2: Nothing

Right bank actuator only plugged in to either right or left bank connector
Fault Codes:
- ECM1: No fault Codes
- ECM2: Fault Code for Turbo Controller 2, missing messages
Output Tests
- ECM1: Boost Control Output Test runs actuator
- ECM2: Boost Control output test does nothing


Left bank actuator only plugged in to either right or left bank connector
Fault Codes:
- ECM1: No fault Codes
- ECM2: Fault Code for Turbo Controller 2, missing messages
Output Tests
- ECM1: Boost Control Output Test runs actuator
- ECM2: Boost Control output test does nothing

What this appeared to me as is that XS boost mismatched the right and left turbos, and really replaced the left bank actuator with one from a right bank turbo.

Lucky for me, I had a pair of remanned turbos from Germany show up yesterday...2 months late...so went at it again with those actuators. Ended with the exact same results no matter which combination of the 4 actuators I tried.

Talked to a friend who is an engineer at Garrett, per him, the hardware between the two actuators is identical, but the CAN feedback identifiers have two different values between right and left bank.

Everything I can find at the moment is suggesting that I am extremely unlucky, and out of 4 actuators, managed to get 4 right bank actuators installed.

Does anyone have any other ideas, or does the logic seem sound? If so, any idea where or how I can have one of them re-flashed? Unfortunately I've burnt up 1/3rd of my vacation for the year with this turd so far, and have the worlds slowest 6000lb paperweight at the moment to show for it.

Really appreciate any help,
Malhon Godwin

Thought i'd bump this, as I've been wondering if the rebuilt actuator I have is reading bank2 instead of bank1 like it's supposed to.

Don't know if this shop tested the PWM frequency like they should have.

Just as a resolution of this all...

Per my first post, per my friend at Garrett, the actuator bodies, boards etc. for a left bank vs right bank turbo are the exact same...they're all the same part that they buy from Hella.

Volkswagen orders a complete left/right bank turbo assembly from Garrett. When the turbo gets to the end of the line, the actuators are either flashed with the CAN identifier bit for left bank or right bank based off of what turbo assembly it is.

The turbo actuators have 5 pins, but only 4 are used. The 4 are +12V, GND, CAN+, CAN-

Other versions of the same actuator are controlled via PWM opposed to CAN. The Touareg actuators run on CAN though.

When a rebuild shop etc. goes to test each actuator, the tester doesn't care what feedback identifier is. The ECMs though do. ECM1 controls Turbo1 which is the passengers side actuator. ECM2 controls Turbo2 which is the drivers side actuator. Note that both ECMs talk over the same CAN network which is what all the different actuators they control are on as well, so its not as simple to debug as check for actuation voltage at the ECM and at the electrical connector at the turbo.

Wen the rebuild shop rebuilt my turbos and replaced the board, they replaced both with right bank actuators. This was confirmed with the output tests in VCDS which would run both turbos from ECM1 and none from ECM2. This was contradictory to what they had said that they replaced the passenger's side (bank 1) actuator and had not touched the drivers side actuator...

I resolved the issue by finding a pair of turbos off a wrecked touareg and swiping the boards from those. That gave me 3 bank 1 boards and 1 bank 2 board to assemble a set of 1 bank 1 and 1 bank 2 board from. This took care of all the issues and the treg has been great the last 10k miles. I still have the other bank 1 actuators if you need one to try out. Let me know.

Thanks,
Malhon

I would actually love that bank 1 actuator. I just sent off mine to this shop automotive scientific inc. (autoecu.com). in Tennessee that said they did many different actuators. When I called, they said they replaced the motor, the wormgear, and maybe a capacitor. It sure didn't sound like they did any testing. He even gave the line that what bank doesn't matter... when I installed it, I got the same error from before. No change. Automatic limp mode as soon as the car starts, runs, anything.


So I have the original that gives 18360 p1952 defective error module 1 . And the "rebuilt" Module 1 that is giving me the 19791 p3335 missing messages error.

Give me a pm or email me Jeremy p mercado at gmail.

Thanks for replying.

Great info thanks

Do you guys have part numbers for the hella actuators?

For the 2004 they are the same g145 717120 both sides right? The armature also looks like it's in the same position (but installing it shows the angles are totally different) this shop is still having trouble programming...

Malhoun, email me if you are still willing to get that actuator out to me. Still can't PM ;(

Thanks,
Jeremy

If you still have a bank 1/right side actuator left, I'd like to purchase it.
