I am new to this forum so please bear with me. My sons girlfriend bought the above vehicle from a corner lot dealership.
i know first mistake however she is only 19 and on her own so she is doing the best she can. Had overheating problem replaced theromstat afterwards bubbling from resouvior. torn down head checked out found two cracks in turbo replaced, water pump replaced, all belts replaced. all good for test run and idling. They went to leave got about 1 block heated up again.
found raditor clogged. My son remember he put white grease on engine to keep no rust from forming whiles waiting on parts to come in. then cleaned out raditor. when to restart car started then stalled out. will not start now. it does crank. there is also a light on dash now that is a traingle with a car inside with a key symbol under it. We are having a difficult time finding someone with volkswagen knowledge. before they started this adventure they called vw repair shop they were told 3 thousand to replace the water pump needless to say this young lady does not have that kinda of money and neither do i to lend it to her. Now we are lost as to why this will not start. any help would greatly be appreicated. I found this site while looking up information for them. I am hoping someone out there can relieve the frustration they are feeling now...

Sounds like the immobolizer is keeping engine from running.
There is a chip in the key which is "read" by the ring around ignition-switch. If this chip is not matched to the dashbaord/ECU, the engine will start but immedeatly stall out. The light on dash that is a traingle with a car inside with a key symbol under it is also an indicator of immobolizer.
Is this the ORIGINAL key that is intended for this vehicle?
Here is some info about immobolizer system.

my son thinks he has somewhat found hopefully the problem. One of the fuses #37
was blown Its the one with the picture of a book on the diagram. put new fuse in
that fuse blew before even trying to start the car. Figuring its a ground but don't know where to start to look. Oh by the way the little symbol disappeared. And I did find out the key she has is the only one, and the dealership never gave her the black tag or they didn't have it to give her.
#107 of 273 06 Jetta 2.0T starts then quits after 2-3 seconds
May 09, 2009 (4:55 am)
it's been at the VW garage where they have now logged 15 hous of diagnostic time with no results.
when it first occured there was a strong electical burning smell?? I would have assumed the VW tech's would have figured it out by now. with no luck I'm hoping someone out there may have come across this unique problem - thanks

I assume you realize that starting and then stalling is *usually* due to the immobolizer kicking in.
If that has been ruled out... suspect that the fuel-pressure may not be stable. (after a few seconds, the pressure gets so low that the engine stalls)

ok update put another fuse in 25 amp that blew after trying to start. Needless to say no start. put 30 amp in car started. but she did show herself ( yes I am referring to the car as a she you will understand later) the ingnition coil on number 3 caught on fire. had to replace the wiring harness and to be on safe side replaced all the ingniton coils. Started right up. yea Car Finally left my back yard after 4 weeks of headaches.
Oh I should have known better then to speak so soon My son came for a visit guess what is staying... yes the car. After all that work now there is oil in the antifreeze.
does anybody have any clue what it could be now.

Oil in the antifreeze ususally means a blown head gasket (or worse).

thanks for the reply but even if we just change the head casket see first message that started all of this #103. Head checked out fine. checked the block everything fine. From what the machine shop told us. But he is going to tear it down again will keep everyone updated. But I can tell you I am getting ready to start using this car as a flower bed. LOL.
#112 of 273 '06 Jetta 2.5 starting issues
May 24, 2009 (9:18 am)
I'll post what I have posted in another forum at vwvortex.com.
Hopefully you guys can help point me in a direction of what to do next as i'm lost as to what my next step(s) should be.
I have an '06 Jetta 2.5, 5sp man, pack 1, with 45,000 miles on it. I have been having intermittant issues getting it started after the vehicle has been previously recently driven. (brought to full operating temperature).
For example; car sits overnight, 7-9, hours in a garage. Get in to go to work, car starts just fine/normal. Car then sits for 3-4 hrs before my next attempt at starting the vehicle where the vehicle cranks but refuses to "fire-up" until it finally gives in and starts after several re-attempts at getting it started. Vehicle then starts but idles quite roughly.
First trip: I mention to dealer progressive difficulty getting vehicle started, dealer advises they do not experience the same issues.
Second trip: Dealer agrees to replace the battery, so now instead of fast "click, click, click" the car cranks (actual engine turn over) with much more intent but still doesn't start in the above situation.
Third trip: Dealer advises they finally experienced and/or witnesssed the problem themselves. Dealer replaces ignition control module. I get it home, decide to go to petsmart but cannot leave as my vehicle refuses to start.
Fourth trip: Dealer replaces the Altenator on the vehicle to no prevail.
Fifth trip: Dealer has had vehicle all week and has put 300 miles on it and cannot replicate issue once again. Dealer takes sample of the fuel to see if possible water in the gas issue? Nothing unusual found with the fuel but dealer notes they find possible mis-fire codes and rough idle issues in the computer. Dealer acknowledges they performed my $600 40k service. Dealer also sees I have never missed any service intervals. Dealer puts in a fuel additive and checks injectors to see if dirty but they are not. And to add insult to injury Dealer employs a group of greased Monkeys to finger paint on the headliner and interior of my vehicle. Dealer makes no comment but new headliner is currently on order and I still have a vehicle that starts but only when it wants too.
What does one do next?
