2000 TDI DTC code question

My father has a problem with his 2000 TDI. I used my VAG-COM
to find the DTC code as follows:

Address 01: Engine Labels: 038-906-012.LBL
Part No: 038 906 012 BD
Component: 1,9l R4 EDC G000AG 2507
Coding: 00001
Shop #: WSC 00066

1 Fault Found:
16764 - Glow Plug/Heater (Q6) Circuit: Malfunction
P0380 - 35-10 - - - Intermittent
Readiness: 1 1 0 0 0

The Part No: 038 906 012 BD is the ECM/ECU. However it is
pointing to the glow plug heater circuit. Is this the
infamous R109 relay control module?

Any help from the RAMVW collective hive is appreciated.
Woodchuck, dave, none, et al.

Thanks!

The 16764 code looks like a glow plug problem. I will have to
ohm out the plugs and see which one is bad. Also check the voltage
on the rail. Sound like a plan?
