I will fist need to know if engine just died,this happened over night it ran out of fuel? it it ran out of fuel you will need to prime the fuel system of air witch may include loosening the fuel injector lines and cranking engine over then when engine starts to fire tighten lines and continue to try until it starts it will run rough and smoke white and then it will clear and be back to normal. it can also be a bad lift/fuel pump or a cracked or broken line,bad injection pump many things just need more info message me if any more questions thanks and good luck

Did you check the battery? Alternator? The 2003 Jetta TDI's are FAMOUS for breaking the alternator pulley right off the shaft. Is your serpentine belt hanging?
You could have a bad battery, broken alternator, broken serpentine belt, or bad alternator among a few other things. If your belt is hanging either the belt broke or more commonly, the alternator puller broke off the shaft.

Is there a plug in for a diesel jetta


I don't believe any VW sent to the US in the past 15+ years has come with a plug-in heater. The only exception is if the car was from Canada, or if one was installed afterwards.

If the engine turns too slowly to start, try cleaning the terminals of the battery, if still nothing- replace the battery.

If the engine turns over but just won't fire up cycle the glow plugs a few times before trying to start. Turn the key to on, wait for the glow plug light to go out after a few seconds then turn the key off. Repeat 2 or 3 times before you try to start.

Also make sure you use a fuel additive for the cold months. Look for something with anti-gel on the label.

It is hard starting my VW 2003 Jetta. It usually take 5 to 10 cranking before it turns over. Then it run normally. It only happens when the car has not been driven for about 6 hours.

If you're car has been running fine, then suddenly won't start, the cause is frequently that the fuel pump cutoff has been tripped. Open your trunk, and look for a label for a fuel pump cutoff switch. Locate the switch, press it in, and see if the engine will start.

My diesel engine on my VW TDI Jetta is having a hard time turning over. It takes forever to start and seems to be getting worse.


Have someone replace your fuel filters ($$$) and put a bottle of "Lucas Diesel Additive" available at Advance Auto Parts $8
P.S. If you have PREMIUM Diesel available in your area (BP-Chevron) run that for a couple of tanks.
Good Luck

Try disconnecting the battery (unhook on of the terminals) wait for like 15 mins, hook the terminal once again and start the car. I also own a 2003 Jetta and once my engine light would come on after 2 mins of driving. Disconnecting the battery is like resetting the computer and hopefully the sensor.

2003 vw jetta wolfsburg bogs on early acceleration


Don't know if it applies to your diesel but most later gas engined vehicles have a 'cold start' valve that supplies additional fuel to the fuel/air mix along with boosting the idle speed until some warming of the engine is sensed.
