Asked by Brennan Jan 17, 2011 at 03:34 PM about the 2003 Volkswagen GTI 1.8T 2-Door FWD Question type: Maintenance & Repair about 1 week ago while I was driving on the freeway my EPC light came on and I had to pull onto the shoulder as I lost all acceleration. After restarting the car I got off the freeway ok (did notice a loud blowing sound though) and got to a gas station, then I disconnected and reconnected the negative battery terminal to reset the system. Since then it hasn't happened again and my car appears to be running completely fine except for one thing: when I give it a lot of gas and really try to accelerate quickly I hear that same loud blowing or sucking noise coming from the engine. I'm assuming this has to do with the turbo since it only happens if I give it a lot of gas, but I'm only guessing here. VW guy claims he has no idea what the problem is until he looks at it for $85 an hour, anyone have a good idea what the problem might be? Case answered 7 years ago Hey man im having the same problem with my 03 gti.

The light first came a couple weeks ago after there was a noticeable shift in power, light tug, feeling of a slight down shift. I preceded to drive the car home and left it parked for the night. The next day the light was off. However after driving maybe 15 miles the next day the same thing occurred, in addition my vehicle began stalling at stops and the EPC light switched to the check engine light. Again once parked the lights both EPC and Check Engine switched off. For the past week this is recurring every time i drive and again the lights turn off overnight. I have taken it to two mechanics whom state they cannot help because the lights do not stay on.

Any suggestions?? Emily answered 5 years ago i was driving my 2003 vw new super beatle gls turbo today my oil light flashed checked my oil full levels then i later read in my owners manual that do not drive your vw if your oil is full and light flashes seek nearest vw dealership. I went to mcdonalds and on my way back home engine light came on car died on 83 in the middle of the road it most likely is my timing belt or hydro pumps possibly a loose sensor but non the less bought this car 3 days ago so they are fixing and replacing all parts for free downside im without my car for 6 more hours. DO NOT DRIVE IF OIL LIGHT FLASHES AND OIL IS FULL. MEGA REGRET FOR MY DAY.

Nathan answered 5 years ago Once about every week or two when i come outside my home and get in my 05 gti and start it up to go to work my EPC light and my ESP light cut on and stay on. If i start driving it down the road, ill get the loss of power. I can pull off the side of the road quickly and restart my engine once with my key and the EPC light will cut off but my ESP light stays on. Start it a second time and the ESP light resets. Still trying to trouble shoot this.

Sensors

Im also not going to a VW dealer so they can tell me 6 other things are wrong and need fixing when they are not. I'll let you know what i find out. 2003 ford ranger troubleshooting guide.

NewGTIdoc answered 4 years ago My brand new 2015 GTI (3 weeks old) just had a similar problem when I was out driving it yesterday. In a parking lot on a hill. Car would start for a few seconds then fail to idle and die. The EPC light was on. Thought it was flooded and tried everything including jump starting by rolling down the hill for about 200 yards. Still nothing. We waited about 10 minutes while we read through the manual to see what EPC meant.

Just before we called the dealer we tried one last time and it started. We drove straight to the dealership and they are now looking at it. Very disappointing. Sactocharlie56 answered 3 years ago I recently had the same issue with my 2001 beetle, 1.8L turbo. This is how I fixed the problem. The middle gear inside the throttle control module was worn. This wear allowed to much play between the servo motor gear and the throttle plate gear.

Computer interpreted this as a slip in the drive train. The middle gear does not rotate 360 degrees. Therefore I lifted the gear out of the assembly and dropped it back in place so the worn areas were no longer in play. No DTC's and operating great for a couple of months. Sactocharlie56 answered 3 years ago The EPC light has to do with the VW's accelerate by wire system. Any anomaly that's associated with the engine rpm, wheel rotation, throttle peddle position and the throttle control module will most likely illuminate the EPC light.

Now you have to figure out which one. Start with pulling DTC codes. If none, then roll the dice. I'd start with the TCM if no codes come up or if fuel metering code P0170 DTC comes up. This comment is entirely based on personnel experience. I have no experience with the other possible causes. If you don't understand what I'm talking about then you need to find a good diagnostic mechanic.

Repair shops just start throwing in parts until it's fixed. A good technician can find the data causing the problem then you can determine which part needs replacing. Read my solution I posted a couple of months ago. James1012015 answered 3 years ago It does the same thing for me I just disconnect the negative Batrey wire for about half hour and all lights are shut of and runs again for 300kilometres or so then epc come on.

I've been told to replace the pressure regulator hose numerous sensors spark plug wires boost leak. What do I need to change every part on this peace before the electrical power control light stops coming on. Can anyone give me a direct genius answer to what the exact problem is??, I don't want to go spend all my money and have it still having problems.
