Question about Volkswagen Jetta

1 Answer

My 2001 Jetta is getting terrible gas mileage along with an acceleration problem. The car takes a long time to warm up. When the car isnt warm the RPM's go only to 200 and only 25 mph. . Even when the car is warm it doesn't run smooth. The car jumps and misses. Please help!!

Start with the fuel filter. Most neglected part of the drive train system. Along with air filters.

Bout a week after getting my 2009 crv i noticed every time i let off the accelerator the car will appear to downshift sometimes it is quite a rough downshift it has done this for the last 8 months. Dealeri...


the car is fitted with a fuzzy logic gearbox,computer controlled within the engine management system.it will try to make you drive as economically as possible taking into account the gas pedal possition/road speed and load.it will also adapt to your driving skills.
so if you drive in town all the time it will change at higher revs and out of town, if you accelerate gently,lower down the rev range.Try this.without using the gas pedal put the car in drive and let the car do the work,it will accelerate on its own upto 4th gear.
then try again, from stop, keeping your foot about 1/3rd down on the gas and let the car do the work try not to move your foot.then, if you can, drive using only a max of 1/3rd gas pedal all the time and you will find within 100 miles the car has adapted to this and your gas mileage will go thru the roof. also the car will adapt to high grade gas.adjusting engine output to match.

How do i fix low gas mileage. the manual says 11 km city and almost 18 km highway driving. however i only get 5 km city and almost 10 km highway


First, high mileage, older car - loss of mpg.
Second, have you heard of keeping your car in good running shape - meaning doing the maintenance an a regular basis?
Change the oil on time, change the air filter, make sure every thing is working right, make sure the tires are wearing right.
All this contributes to good mpg - but older high milage - loss of mpg.
Can't fix that!

Jetta 2005, gas pedal not responding,,sometimes it does, and sometimes it doesnt. Usually happens when the car is warm.


This is a "Drive by wire" car on the throttle. There is no accelerator cable, it has an electrical sensor that tells the engine computer when you accelerate.

Sounds like the sensor is going bad. Take it to a shop and get it replaced.

2001 Jetta 1.8 turbo - a/c intermitently goes warm during idle, and sometimes hear a loud vibration that comes on at off, all during idle.


its prob the cooling fan its located in a housing along with the radiator fan at the front of your engine bay look down when you open the hood . and make sure the fan is spinning run the ac on high and wait ( do this while the car is running of course ) . do not run your ac if the fan isnt working . you will burn up the compressor . the noise and vibrations you feel are from the compressor turning on and off.
now if the fan is working its prob the compressor. if all else fails take it to a mech where they can test it ... its not pricey and its quick

I have a vw golf mk 4, when the car is warm it doesnt want to start, When its cold it starts first time with no problems. If i manage to get the car started when its warm and put my foot on the accelerator...


It could be your coil pack. they pack up on mk3's and im sure its a similar type of unit. try cooling the coil pack down with water when the car is warm to see if it is that unit. be carefull not to get too much water on the warm engine as it can do harm to it.

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.
