19804/P3348/013128 - Control Circuit for Controller for Turbocharger 1 (J724): Electrical Malfunction
Possible Symptoms
Malfunction Indicator Light (MIL) ON
Possible Causes
Fuse(s) faulty
Wiring and/or Connector(s) from/to Controller for Turbocharger 1 (J724) faulty
Controller for Turbocharger 1 (J724) faulty
Possible Solutions
Check Fuse(s)
Check Wiring and/or Connector(s) from/to Controller for Turbocharger 1 (J724)
Check/Replace Controller for Turbocharger 1 (J724)
Perform (Selective) Output Test, the Vane Positions should change visibly and audibly
Perform System Test using VAS 6395
Special Notes
When stored in the 3.0l TDI (ASB/BKS/BMK/BNG) with throttle body faults P106B/004203 and/or 17988/P1580/005504 check the throttle unit and wiring for issues that may be falsely causing the turbocharger fault.
If the wiring is ok then you are looking at a new J724.

4 pins or 5
I've looked that diag info you pasted - thanks again. Either i'm on a different revision or i'm looking the wrong place for the controller module.
The diag asks to test pins 1-5 but i only have 4!
I'm looking at centre of the engine nearest the windscreen. The module is slightly to the left when facing the car.
Thanks,
J

Your control Module is on your Turbo. Below is a overview (#19 on the page)
I do not have diagram of the plug. I do know you need a program to plug into the turbo to check your system. VAS 6395/1 if you do not have this you are stuck to go to the dealer.

This is what the VAS looks like which you need to reprogram.
