Question about 2003 Volkswagen Jetta TDI

1 Answer

Momentarily Sluggish Acceleration

I have an 02 Jetta TDI with standard 5 speed. The first time I accelerate after all engine startups it has a very sluggish acceleration for a moment (less than a minute) and then will boost into the normal acceleration, almost like a kick of power, and will run great until I turn the car off for a moment and restart, it then repeats this lagging acceleration again. This happens on every single engine startup on the first acceleration only, and then accelerates perfect after every stop.

Are you loosing power to the ecu when the car is shut down? most cars with an ECU that controls timing, fuel, or boost can be forced to relearn the car if the ECU looses power (called a "limp" mode). I'd look into this. Also are you getting any check engine lights? considering the description of the problem, this would help to diagnose. Try getting the car started and running normally, then turn the car off but do not kill the power to the car, just stop the motor from running...Fire the engine back up and try to give the car a good stomp on the gas and see if you get the same sluggish problems...my 2 cents... Good luck future auto DIY's

Sluggish Acceleration


A high mileage vehicle usually suffers from any number of maintenance related deficiencies. I would address the Fuel filter maintenance first. It's the cheapest and easiest of the solutions. Lack of fuel pressure under higher demand due to acceleration will result in a sluggish engine. The engine would idle fine and even run fine at high speed but would be sluggish under acceleration. Other more complecated solutions would be worn Ignition coils, Worn spark plugs, Timing belt stretched or jumped timing and the most expensive would be loss of compression in the cyllinders.

Check timing of the engine is right using an engine timing light. Make sure the timing belt or chain isn't worn or slack. The head gasket could also have gone and may need replacing.

I have 2000 VW Jetta 1.8 turbo, my car stumbles on acceleration, but run smooth at idle. I removed the air intake from the mass airflow sensor and the car died. Is the turbo bad or do I have another...


If you remove the mass air flow sensor then the car is getting to much air and the reason that it is dying is that the ECU is set for the engine to run with a specific air to fuel ratio, and if you have removed the breather element. or air filter then that can cause the slow or sluggish acceleration.

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.
