      posted this on tdiclub, but might as well check here too...


      My girlfriends 2000 Jetta TDI starts hard in the cold. The first start will take about 6-8 seconds of cranking to kick over and idle is 100% perfect right after hard starting. Here is some other info...


      1. new starter (non-bosch)
      2.battery is good (vw checked)
      3.4 new glowplugs (bosch)
      4.injection timing was checked, vw said upper middle and told me it was pointless to change.
      5. cycling the glowplugs has an small effect, but does not solve the problem
      6. even on the coldest day, once it starts you and turned off quickly ( 5 seconds of running) it will fire back up instantly (like summertime) no problems.
      7.I have cleaned the EGR valve and the intake is about 70% open.

      what to do next? any ideas

      How old is the battery. If you put the timming in the midlde of the top 2 lines it should help some. My timming was set close to what you are describing and my car still seemed to start hard. Changed it to around 68 and its starts easy now. But it doesn't get cold here like it does up there.

      Air leak around your fuel filter?

      How Many CCA is your battery putting out?
      During one of the cold snaps this winter my battery was putting out ~225 CCA, and my car would not start, (that's when I got an Optima! my car starts instantly all the time now, when it was taking almost two seonds of cranking)
      AutoBone brough out their Battery tested and said, your battery is good, but I looked at the reading and said, only 225???? a new battery puts out ~700.

      Can I rule out the battery if the car will restart instantly after only 5 seconds of running? wouldn't the second start be harder because the battery would be weaker???

      Are the glowplugs actually glowing?

      how do I check that? it would appear they are because cycling the plugs seems to help a bit and I can hear the relay click.

      The glow plug seems to be on for the correct amount of time. What would the problems of a coolant temp sensor be???

      When it does start does it kick out a big cloud of black?

      I wouldn't say an excessive amount, but there is quite a bit of blue smoke

      If it clouds the heater plugs aren't getting hot enough, if not it's lacking fuel, might be draining back to the tank.

      How would you make the glowplugs more hot??

      This is why I mentioned the coolant temp sensor. The glowplugs will only work if the temp is below a certain point. If the temp sensor is messed, they could be getting a incorrect reading. For the $7 it costs, I would replace it....

      You can also increase the time the glowplugs are actually on within VAGCOM... If you haven't allready come over to TDIClub and make a post...

      would a failed temperture sensor effect the length of time the glowplugs are on for or how hot they get? the glowplug light on the dash seems to be on for the correct amount of timevs cold

      That's why you need to remove a glowplug and test it, it should glow red.
      Low voltage/current will make them work poorly.
      Use a voltmeter to test how long the glows are on for before you go swaping in new parts.
