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.

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.

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.

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.

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.

Engine light stays on all the time. I've had it fixed twice but it continues to come on.
