Jetta Will Not Start...!!! by badvw7
May 16, 2007 (11:11 am)

I have a 2002 VW Jetta GLS TDI that will not start... It will not even turn-over. The battery is confirmed good. I believe that their is a problem in the automatic shift lock system. When I turn the ignition to the On position the "brake pedal light" (ASL light) momentarily comes on then goes off (supposed to stay on until you depress the brake pedal) and I hear a relay click in the shift console (It is an automatic transmission). The "Automatic Shift Lock" light should stay on until I press down on the brake pedal, which then allows you to shift from park into the desired gear. I can shift it freely into any gear even without pressing down the brake pedal. Also the electronic gear indicator on the dash does not indicate which gear I am in. It just flashes on and all the gear indicators remain lighted. I am not so sure that this is a brake light switch problem. The brake lights work normally when depressing the brake. The switch also ohms out normal with an ohm meter. The switch is purple in color if this means anything. Please someone help ASAP...!!!

I own an '03 Jetta manual transmission (2.0). For some reason all electrical went off (power windows, radio, lights, clock, etc) when I attempted to start. It appeared as though I had a dead battery, but after a few seconds the lights and all came back on. I attempted to start engine, but all that occurred is that the engine seemed to go through a sequence of checking certain items... power lock on doors unlocked and other clicking/beeping noises came on, but engine did not turn. Then all electrical went off. After waiting a few minutes all electrical came back on, but the same sequence occurred when I attempted to start. Any and all suggestions welcomed!

Did you have your timing belt replaced yet? If not, i'll wager the waterpump is the problem. The impeller on the waterpump is made of plastic that will disintegrate and block the passages in the cooling system at best (which may trigger the coolant migration) or seize at worst - causing the timing belt to strip and break, introducing the possibility of a very expensive engine replacement.
 
I had the timing belt changed on my 2003 Wolfsburg Jetta 1.8T (73,000 miles) and my wife's 2003 Passat GLS 1.8T (68,000 miles) - and in both cases the waterpump was on the verge of disintegration (both pumps were replaced with the improved version with a metal impeller).
 
If the timing belt/waterpump has been changed before the 80,000 mile interval, I would make sure the coolant level in the expansion tank does not exceed the full line - which is the halfway mark in the reservoir. The upper half of the reservoir needs to be empty so the coolant has sufficient room to expand. Too much coolant in the reservoir will cause the coolant to overflow out of the reservoir - another way of producing the coolant migration condition.

trouble cold weather starting my 97 jetta 2.0 by taguchi

thru march and april here in canada, we had a few cold snaps where the tempearture dropped overnight by 10 degrees or more. My jetta didnt want to start after sitting in the cold on these nights. no problems over prior winters. no problems if I didnt leave the car too long without turning it over. battery and starter working fine. I figured out that i could get it going by letting the starter turn over a few times, then pumping the gas as i released the ignition. Ive heard a few theories from bad gasoline to clogged filter. I've replaced the fuel filter, fuel pump and air filter but the problem returned. My volkswagon mechanic is stumped and says he needs to see it in the "wont start" condition...which means waiting till it gets cold again. Anyone heard of a problem like this b4?

I have a 1997 GLX VR6 with the exact same problem. When the car is parked in a hot parking lot and the internal tempeture in the cab is hot, the car will not start. If I roll down the windows and wait for 5 to 20 minutes the car starts. When the cab is cool the car starts with no issues.
 
Does anyone know what the problem is and how to fix it?

I figured out what was keeping my 97 jetta from starting when the temp dropped and humidity went up. It was simply water condensing in my gas tank. a few bottles of water remover has solved my problem. Hope your starting problems are as simple to solve.

So, lately my car has been hard to start in the morning for the last few days. I woke up today started it and it finally kicked over after 4 tries when it did the engine revved up to 2100rpms and then came back down to 1500rpms and now it constantly revv's up and down between the 2 like a teater totter. I looked inside my engine and noticed a little white smoke was coming from the engine not much but a little. So then I get back in the car and put it into drive and the revving stops however now its idleing at 1400rpms. I need help on how to fix this hopefully in an inexpensive why please let me know what you think it might be

Random engine shut off by jjhoglund

1997 2.0 jetta gls. aba motor.
After starting it will run for anywhere from 15 to 45 minutes and then shut down. It will not restart for at least 5 minutes. Upon restart it might never quit again or it might quit after another period of time. It doesn't run rough or give any other symptoms that its going to quit. It just shuts down. No engine light. Looking for ideas.

You may get more TDI related info from the TDI-specific forums.
 
However - starting then shutting off immeadiatly is often related to the immobilizer kicking in. (It thinks the car is being stolen)
