V10 TDI turbo actuator cross compatibility

Trying to figure out what turbo actuators will work with my 2004 Touareg V10 TDI engine code BKW.

Bought it thinking it may need the engine pulled for new turbos due to codes and no boost. Found bank 2/left side actuator unplugged, plugged it in and now i have half boost. Bank 1/right side sets a turbo controller missing messages code, and produces no boost on that side. I took the actuator apart, looks good inside, and the motor spins easily if i apply 12v to it. Plugged it into the left side, and it still won't work. So I'm certain the controller is dead and it's not a wiring issue.

Now I'm on the hunt for a replacement bank1/right side actuator. As I understand it, they must be coded as left or right (bank 1 or bank 2). On my bank 2/left actuator (working side), the numbers are 730314 6nw-009-228, yet on the bank 1/right actuator (non-working side) its 712120 6nw-008-412 G145.

My question is, what actuators will work for my bank 1/right side? does the Garrett number matter, as long as its coded for a V10 TDI bank 1/right side? Could I use a 730314 on the right side as long as its coded for right side?

I believe that the controllers are the same from side to side.
BUT when they are fitted that becomes their location they cannot be refitted in the opposite side.
I also believe that they can be swapped from engine to engine provided it is the same location/side they came from.


I believe if you purchase an expensive coder of some kind you may be able to recode to swap sides.


Plenty of turbo's for sale out of Europe

That's what I figured. Just purchased a right side actuator from a 2004 V10 TDI. Hopefully this gets it sorted out.

Hi did you fix your boost problem?

Havenít received the actuator yet, despite being ordered two weeks ago...

Finally got my actuator from Germany after a month. Seller stated it was in good working condition, and for the right side. Plugged it in, and still got codes for missing messages and no operation during output tests. Opened it up and found the drive gear broken.

Swapped the circuit board onto my good gearbox assembly and plugged it back in. Still got a missing messages code.

Found another one from sale in California, but it's $500.

How much is a new one? EST tuning maybe.

The only way you can buy a new actuator is by purchasing a new turbo assembly. Garrett/Hella don't sell the actuators separately.

Ok what about having the circuit board repaired, like when you get the KESSY module repaired

UPDATE - FIXED!

Haven't had much time to tinker on the Touareg, been mucking with my MK1 16VG60 for the past bit. After trying 3 different actuators and having no success, still receiving "missing messages" codes for bank 1, I busted out my multi meter and found that the CAN-HI wire on at the bank 1 connector had high resistance. Followed the wiring to the splices under the plenum fuse box and found it all green. Repaired the splice, ran output tests and.... BOTH ACTUATORS MOVED! BUT - i still had a "missing messages" code for bank 1. WTF?! After some more diag I confirmed that I had received 3 bank 2 actuators, despite the sellers assuring me they were from bank 1.

Long story short, I plugged in the original actuator that came with it, cleared codes, ran tests and every works peachy keen! Took it for a good drive and holy crap! I've had several 400hp Audis, but the torque of the V10 TDI is absurd!

Poor splices seem to be an issue on these trucks, I've never heard of any other VW/Audi having so many issues that are due to bad factory splices.
