2000 TDI DTC code question

Feb 04, 2008 3 Replies

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! PP


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?
