EPC light came on and lost all power a week ago, having strange problem now. Help please!
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?
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??
someone posted on another website I may have a boost leak, but they were referring to how I mentioned I hear a blowing noise when I give it a lot of gas. My lights haven't come back on, but last night my MIL light came on (malfunction indicator light* I believe is what it stands for). Yet again the manual is very vauge about what can cause it, so I don't know whats going on. If I hear anything about the lights I'll post it on hear for you.
i had the same thing a year a go took in to vw it was fule senser today i have the same problem i need to take it back
Check the vaccuum lines. mine had the same issue so i replaced my vaccum lines.
Epc light is mostly known to come on when there is emissions probelms. Could be Lambda probe sensor (o2) on cat.
the check engine light deals with emission related problems. if there is a loss in engine power then thats when the epc light comes on.
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.. YOUR CAR WILL STALL **** JUST TAKE IT TO THE VW DEALERSHIP.... hope thats helpful... - em

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. 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. haha.. I'll let you know what i find out.
yes, i am having the same problems with a 08 DSG model, i've had the accelerator cable, accelerator and another valve replaced so far. its still happening! driving along and suddenly the EPC light will come on and i'll loose power, its really dangerous. does anyone have a fix for this problem??
Had same problem.. Getting it back today.. They said my second cylinder was missing.. So I'm guessing it was a spark plug.
I have a 2008 city golf done up a bit. When I put a cold air package on it and racing exhaust. The epc and red exclamation mark comes on. I have no loss on power just that lousy beeping warning. I took the negative off and nothing. It came on once. Went away and 2 months later came back

this happining now to my 2004 audi a4 quattro 1.8t
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.
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.
I'm having the same problem with my 2010 polo when I start it it's rev counter is a bit too high and when I try to drive it doesn't pick up speed. The EPC warning light is on it started to last night
