While driving my 2003 Jetta TDI last night accelerating up a hill my battery light came on and the car died. All other lights work, glow plug light still comes on. Engine turns over but does not fire. Checked the relay and the anti shutter valve. Any ideas?

sounds like alternator failing and not charging the battery or dead cell in battery or could be belt going to alternator slipping check the tensioner

Sounds like the immobilizer, do you have another key you can try?

Check your relay and wiring bridge. Either could be faulty and throwing a glow plug code. Start by diagnosing the relay since this is the cheaper of the two. Go to the TDIclub.com forums and look up glow plug and you will get an excellent writeup on exactly how to do this.

Get some electronic parts cleaner from radio shack or a electronic parts store, remove each glow plug terminal and spray liberally and reinstall with dielectric grease, this may not work, hate to say that, but you may have to replace the wiring loom to the glow plugs, they are not the best quality wires, they other issues may be related to corrosion too, try the cleaner and dielectric grease has solved a lot of problems for me in various cars. good luck

this is a common problem for these cars glow plugs go bad like spark plugs however the smoke would lead to bad mass airflow meter. it is not telling ecu corrcet miss. disconnect mass airflow meter. when cold see if this makes it start better. it should would means you need new m.a.f. glow plug issue take a test light place clamp on positive of battery then pull off glow plug connectors place tip of test light on glow plug the bad one will have a dull light unlike the good one which will be brighter. will need new plugs and wire harness four **** connectors and wire striper and crimper will fix concern good luck

needs a new alternator, going down the hill, your RPM's dropped and all of the draw on from the electrical system came from the battery, and caused the battery to die too

Count the shifts. It sounds like you are going into overdrive and staying there. Overdrive is too long legged to pull most hills unless you are really flying.. good luck

Sounds like it is telling you that you need to get a glow plug replaced that is not functioning properly. Have a reputable shop let you know which one it is.

obviously there's a problem with the system... your best SOLUTION is take it in for proper DIAGNOSIS.. ya think?

how many glow plugs are there and where are their locations
