EPC LIGHT WONT STOP in my 02 Jetta


When was the last time you changed your Air filter( A dirty filter can put MAF sensor out of range). How about the fuel filter (Fuel starvation). These filters should be changed every 30,000 miles . It is normal for all of the dash lights to come on if the engine stops running. Is the Jetta a Diesel or Gas. Perform The OBDII scan again to see if current faults are present. Do the cheapest fixes first. Also check oil often. The low oil sensor will trigger engine shut down if more than 1 quart low

Sound like she's idling too low.You're going to have to adjust that.You might want to check the spark plugs and plug wires...sometimes the plug wires can slip off and it feels like you went down a few cylinders.If it feels like it's going to cut out on you put her in neutral,that will take the strain off of the motor and what not.You should go to Auto Zone and get them to hook up to the car's computer to see what's wrong.Auto ZONE does it for free.Or if you have a mechanic friend that have a diagnostic meter, he/she will hook it up to car's computer also and it will tell you what codes are coming up and the mechanic can tell you what they mean and how to correct them.GOOD LUCK!

Hi

You need to go to a shop with a code reader. The check engine light was telling you something and you need a code reader. Depending on which country you are in, if in the states autozone may have it for free.

Whatever initiated the light is now messing up the other parts of the car.

Hope that helps.

When im stopped for awhile the engine stops and the rpms mess up


do the procedure below to clean the intake and idle speed control valve, they get sludged up and cause this complaint. aldso have you had the system tested for codes?
I want you to get a can of intake cleaner (ABOUT $5.00) from any local auto parts store like NAPA or Carquest, do not use carburetor spray, intake cleaner only or u will damage the Teflon coating inside the throttle valve and air bypass valve, it is made by a company called CRC, remove the air intake hose to the engine, hold the idle high so the engine won't stall, then spray the can of cleaner into the intake while keeping the engine running, use at least 1/2 the can, shut down the engine and disconnect the battery for 5 minutes, then restart and complete a number of mixed driving cycles, town, freeway, stop and go etc., after a few days the problem will go away as the system will relearn to the clean intake.

2003 Jetta 1.8T looses power while driving


Easy DIY is to change all fuel, air, and oil filters, do full tune-up, and change ignition cables, too. See if problem goes away. Take a look at coil, too, those cars have a known coil issue and it needs replacement every 25,000 miles

Hey Guys.. This problem is the Coil Packs. There is a recall out on all 1.8t Motors. If you haven't had an issue, its no rush but should be completed. If you have the sputtering, low power, struggle from the engine, bring it in to an Audi/VW dealer. They'll fix it free of charge. Done and Done.
