I just bought my blue 2002 Jetta GLS TDI this month and have been busy changing filters and ordering parts! It's awesome to find such a helpful website and forum to help me along in learning to take care of the car. It's great to be here.
My car has 130K miles and it's in a pretty good cosmetic shape. The seller told me it needed a new battery because it would need to be jump started sometimes. It drives fine after I installed a new vw OEM battery. EDIT: it is now failing to start up after five days since the battery install. The battery voltage is 10.25. I just started charging the poor battery with Schumacher XCS15 on 10 amp "turtle" setting. Should I have peeled stickers and unscrewed the battery vents(?) when I installed it? I'm new with batteries. I forgot to mention that there are wires for XM radio unit hanging in the glove compartment from the previous owner, one audio jack, one power jack, and two antenna jacks. I insulated the power plug with plastic bag and tape. Last week I changed intake filter, cabin filter, fuel filter, and got a member from vwvortex to run VAG-COM scan because there was check engine light. The error codes were:
17056 - Cylinder 2 Glow Plug Circuit (Q11) Electrical Fault
P0672 - 35-10 - - - Intermittent
17058 - Cylinder 4 Glow Plug Circuit (Q13) Electrical Fault
P0674 - 35-10 - - - Intermittent
00668 - Supply Voltage Terminal 30
008 - Implausible Signal - Intermittent
01330 - Central Control Module for Central Convenience (J393)
53-10 - Supply Voltage Too Low - Intermittent
00929 - Locking Module for Central Locking: Front Passenger Side (F221)
54-10 - Incorrectly Equipped - Intermittent
01331 - Door Control Module: Driver Side (J386)
53-10 - Supply Voltage Too Low - Intermittent
01332 - Door Control Module: Passenger Side (J387)
53-10 - Supply Voltage Too Low - Intermittent
01359 - Internal Central Locking Switch: Passenger Side (E198)
27-10 - Implausible Signal - Intermittent
01333 - Door Control Module: Rear Left (J388)
53-10 - Supply Voltage Too Low - Intermittent
01334 - Door Control Module: Rear Right (J398)
53-10 - Supply Voltage Too Low - Intermittent
Q1: What should I do about the voltage codes? Are the low voltage codes likely caused by the old battery that I have since replaced? We haven't cleared away any codes yet.
00668 seems to be likely caused by loose above-battery fuse or cord. I looked at that box and saw that everything is tight, not burned out, and clean. I did see that the line that connects from the battery + pole to the fuse box on the left has some melted insulator and scorch marks. around the metal sheet that gets bolted on to the main + line.
00929 could this incorrect equipment draining my battery?!
I followed some excellent guides online to test the glow plugs with a multimeter. Glow plug number 2 (second closest to battery) had different resistance from the other three, so I just ordered 4 Bosch glow plugs online.
Q2: I wonder if I also need to change the glow plug harness, because the harness tips for glow plugs #1 and #4 have their plastic sleeves broken off, so that when I pull the harness the wire and metal contacts come off but leave the plastic sleeves on the glow plug ends. I have photos of that:
The trouble code for glow plug #4 seems to be not caused by any difference in glow plug resistance but rather caused by a bad harness contact? Q3: Should I fix this by cleaning the contacts or go ahead and order and install a new harness? Q4: If so, is there different new harnesses options I can choose from?
I checked Relay 109 to make sure it was gray plastic color type, not the problem prone black plastic color type.
I'm arranging with Matt from VA to change my timing belt, so I can hang out and learn (and hopefully not get in the way):bowdown.

I found a long steel spring by the passenger seat. The person who gave me the VAG_COM reading said he also has a collection of those springs, but did not know how or where they fit. Q5: Can any one give us a hint to where the springs go, or a previous post about putting them back where they belong?
The back lights for reverse gear are glowing fine, but they seem too weak to adequately illuminate the road, electricity pole, or slow moving children in the dark. At least it seems like I'm backing into a dark void compared to backing a Tacoma/Altima and seeing an illuminated drive way.Q6: Are dim back reverse lights normal for Jettas?
Let's see, what else. Oh, Yesterday I went to the local biodiesel station and filled up some B99 fuel. I'm changing the engine oil and filter next EDIT: when I fix the battery drain problem. The car is doing great other than the battery drain problem EDIT: I just checked the power steering fluid and it was waaay low so I'm refilling that tomorrow, or leave it and call the steering wheel a work-out machine.
Thank you for reading my first post. I hope to learn quickly and share my knowledge here in the future!:nana2:
