Great write up and instructions....I've had my CEL going off now for 6-7 months showing #3 glow plug being an issue. I kept reading and clearing the CEL to make sure there were no other glow plug issues.
About 7 weeks ago I needed to change my battery and decided to check the glow plugs with an ohm meter. All checked within reasonable limits and all are good.
My CEL has not triggered since and the car runs great. I have a feeling the battery may have been the culprit. The old battery as it turns out was undersized, including under spec cranking amps for the TDI. The new battery is the correct size and cranking amps.
