Received CEL after cold start. VAG-COM reports:
1 fault found:
16764 – Glow plug/heater (Q6) circuit malfunction
P0380 – 35-10 - - - intermittent
TDI details: 2000 Jetta w/auto – completely stock @ 55K miles - first time TDI owner - purchased back in May.
Details: This morning was the first 30°F cold start since my purchase, and therefore the first time noticing glow plug light on for more than a second (in this case ~3 seconds). Car starts normally. CEL appears about 5 seconds later. No drivability problems. Cleared DTC on lunch hour, no more CEL (for now).
Here’s what Bentley reports:
16764 P0380 Glow plug monitoring, No display
• Glow Plug Relay -J52- faulty
• Glow plug faulty
• Different glow plugs installed
I haven’t found any posts on the DTCs, but read lots on Relay 109. Also noticed Bentley interprets “intermittent” as possible loose connection. Will apply grain of salt to verbiage between VAG-COM, VAG-1551 and Bentley CD.
Guess I’ll be probing the glow circuits with a multi-meter this weekend.
QUESTIONS:
Anyone familiar with this fault and/or able to decipher Q6, 35-10?
Any recommendations on testing glow plugs (resistance range / operating current range / etc.)?
Other suggestions?
