welcometomyturbodies Welcome to the website!

How are you determining that your car "keeps faulting the #3 glow plug" ??

If you're going by a scanner (VCDS/Vag-Com) readout, keep in mind that just about all 2002 and 2003 TDIs report the glow plug numbers in reverse order to the cylinder numbers... So your #3 glow plug is on cylinder #2...

Have you actually measured the resistance of all the glow plugs? You'll need a digital ohm/multi-meter that can read down to approximately 0.8 ohms... If they all show up at more or less the same resistance, the problem's often in the harness (your car has a 4-wire harness) - sometimes called "bridge"... Corrosion builds up in the contact areas... many people have had success (at least for a while) spraying an aggressive anti-oxidizing agent like DeOxit D5 and scrubbing with a Q-Tip that's had most of its cotton removed... Some people go farther and gently squeeze the fingers of the harness at the contact area (Be sure not to crush it completely... I find that needle-nose Vise-Grips work well, as you can set the size to which you wish to squeeze...)

If you do replace a glow plug or four, buy them from the well-known online suppliers who charge between $40 and $55 for a set of 4... Bosch or Beru only, please...

glowplug contact cleaning

:nana2:I have had an ongoing issue with glowplugs throwing a cel unless i cycled the ignition twice before staring when engine was cold. I bought a scan tool , got used to clearing the cel it happened so often. Was all set to replace the plugs, but gave them 1 last cleaning- I used a strip of scowering pad and scrubbed at the tips until they looked polished- before they looked slightly discolored but no corrosion. I then cleaned the terminals in the harness with electrical contact spray. next i put a generous amount of dielectric grease on the glow plug tips. What do you know? No more cel! This was 3 weeks ago and counting.

What about a Jetta 2009? Will #1 start from the right or the left? Keep in having 05076 from my VAG. Also I have 00386 which I can't find nowhere

Thanks

I've never heard of 05076 what are you using to scan the motor?

VAG Error Code: 00386


Fault Location:
Negative Output Audio Channel for Speech/Telephone

Possible Cause:
Unknown Symptom, Cause or Solution.

Keith do you agree that VAG will give the reading from right to left. So #3 will be the third one from the timing belt?

I believe it's cylinder number for everything except the glow plugs. Those go by bus number, in other words, cyl #1 is glow plug #4, cyl #2 is gp #3, etc. I haven't double checked this on the newest CRD diesels.

Such is the case in the 2002 and most of the 2003 TDIs... I'm quite sure that by 2004, the BEW engine had the glow plug numbering reversed to coincide with the cylinder numbering... is your BRM not the same? (can be easily checked by disconnecting one glow plug and running a scan...)
