Volkswagen Jetta Problem Report
Volkswagen Jetta Engine Misfire Due to Failed Ignition Coil, Spark Plug, or Ignition Wire
An ignition coil or spark plug may fail unexpectedly resulting in an engine misfire and possible illumination of the Check Engine Light. Vehicles equipped with spark plug wires may also develop a misfire caused by a failed spark plug wire.
When ever it rains my jetta is almost impossible to start. I've replaced plugs,wires,cap and rotor button' I guess next step is to replace the coil??? - Visitor
I was driving when loss power and motor felt like it was jumping. Engine light came on and off. The EPC light came on also. Diagnose that needs coils replaced and ground wire. - Visitor
pulled the wire that goes from distributor to ignition coil off while car was running, stopped running. put back on and it wont start at all - Visitor
Engine started sputtering and shaking as you accelerate- feeling as if you were about to stall out and stop sign, light or while driving- car is serviced as book suggests but check engine light came on and daughter has car at school (drives it very rarely)- SAD that it was purchased certified used vehicle but couldn't make it to 45000 miles without a 600 repair- and then suggestion to do 2000.00 more in repairs even though we let VW dealer know we had already done the suggested service at each mileage point- very disappointed that VW really didn't live up to expectations. Never had a vehicle with so few miles require more than maintenance to perform. Not to mention this car has NEVER gotten the mileage that was promised by the dealership of 26 to 31 miles- if it ever got 18 mpg that would be a miracle. - Visitor
I don't know what is wrong. I have the check engine light on. A tech at a mechanic shop told me its a misfire at cylinder #5. I need to be shown how to change whatever I need to change to get this fixed myself. It is too much money to have mechanics do the job. I also have the ABS light going on and telling me that ABS failure/failed in the dashboard digital display. - Visitor
Check engine light came on, and a mechanic determined the coils should be replaced. However, they had already been replaced at some point because of a recall. I had the mechanic turn off the CE light, and after driving it 200 miles, it never has come back on. - Visitor
CAR WOULDN'T START WHEN IT WAS RAINING AND WOULDN'T START UNTIL AFTER IT HAD DRIED OUT..REPLACED IGNITION COIL - Visitor
coils continually failed, finally got rid of the vehicle - Visitor
Regular 2.0 not turbo. Started to lose pick up and died engine light came on. Engine light went of and drove ok for a day and did it again and again. I took to dealership after changing spark plugs and wires. They diagnosed a bad coil and told me they could see It arc with water spray. I paid the $650 and haven't had any issues for a week. keeping fingers crossed. - Visitor
Engine light stays on all the time. I've had it fixed twice but it continues to come on. - Visitor
my car started up fine and when i went to take off i got to the end of the street let the clutch out while in nuetral and my car stalled and when i tried to turn it over it wouldn't start. my friend who is a mechanic figured out it is the spark plug wires and we replaced the distibuter cap plugs wires and everything seems to be back to normal :))) - Visitor
Cylinder 5 constantly melting, still diagnosing - Visitor
While driving the car will sometimes miss and sort of bog out. The check engine light will flash and the EPC light will come on. Sometimes the check engine light with stay on for a week at a time and then go off on its own. Sometimes when I try to start it it will start and then die out right away. But when I pop the hood and wiggle the wires that go to the coil pack it fires right up and runs great. I have brought it to VW and they said they cannot find anything wrong with the car.. It's having the issue more frequently now and I'm not sure what to do about it. - Visitor
Coil gone bad - Visitor
Trouble starting the car when it is raining. When it does start, the car shakes and the check engine light comes on. There is a burnt smell. I ALREADY REPLACED THE IGNITION COIL. The problem still exists when it's raining. - Visitor
I have the 2.0L non turbo motor 2011 jetta s. Was driving when I accelerated the vehicle when it started to jolt and lose power. The check engine light came on flashing along with the EPC light. When dealer examined the vehicle the engine codes were P0300 P0302 and P0303. When dealer examined vehicle they discovered cracks on the ignition coil. Problem was repaired by replacing the ignition coil at that point in time. Was told if issue happens again could be the coil being defective, spark plug wires and or spark plugs need replaced, or vehicle fuel was bad. - Visitor
EPC light came on and car lost power. The catalytic converter light was also on. Took to the dealership and was charged $332 for ignition cool replacement. After watching a video on this procedure, I wish I would have done it myself. The part cost about $64 and it takes about 10 mins to replace only needing a flathead screw driver. - Visitor
My car miss fire cilyndro 2 and 4 I alredy change the spak plug and the coil pack - Ronaldodias
once warm the car spits and sputters. shuts down then doesn't want to start. Cel is on - Visitor
car was misfiring and shaking and was not able to go above 45mph. Check engine light flashed on and off and then stayed on. Next day drove better on way to garage but diagnosed that central coil was not working properly and voltage was fluctuating incorrectly. Recommended replace coil and strongly suggested that only use VW approved spark plugs and wires since other non-approved wires and plugs can cause damage to coil a month later. Mechanic is NOT a VW dealer either. - Visitor
