Hey guys I was wondering if you found a fix to any or all the problems in this thread. I dont have a GTi or Jetta but my new beetle is doing pretty much everything
that all of you are describing. I already have a thread on the new beetle forum but since we are all in the same problem maybe you guys can give me advice. I replaced
the crankshaft sensor, and I am getting a new 409 relay today. I also ordered a new ignition switch to change tomorrow to see if that helps. My beetle is a 2.0L 4 speed trans.
2001, any help will be greatly appreciated before I go to the stealership.
Also, I found this thread from you as well: https://forums.vwvortex.com/showthre...r-has-gone-mad!
There you said it runs and drives fine. Sounds like you may have multiple things at play.
Have had this happen multiple times on my 2012 Jetta SE. Been to Volkswagen and Autozone to check my battery and alternator and both said it was fine. Volkswagen is no help at all they just said everything was good and then charged me $130 for a diagnostic when I told them this was happening to me.
Anyways I saw a forum post on a different forum (jetta junkie I think?) that said the culprit was the power supply relay. I just had my relay replaced (under the dash) at a local shop last week. Hopefully it's the fix because it's very scary having this happen. Currently no issues but only time will tell, sometimes it's months between incidents where my car dies while driving. Hopefully this car can last me a few more years before I can sell it off or scrap it and get something else that won't try to kill me..
Also, fuel reserve? What do you mean by that?
So I thought that the fuel reserve is the red area on the fuel gauge...so my empty for some reason is at the start of the red area. I understand that you read on my other thread that
the car is running perfect and it is, until it shuts off on the highway. I live in Maryland, today I went to Baltimore I put 273 miles on the car today. The car was running perfect till it hit 134 miles from when I started driving, it started to hesitate I put my foot on the gas and after like five seconds of hesitation the car kept going. After that I went to my friends house and on my way back on the 204 mile the car started hesitating again, it started back firing and going down in gears it seemed like, until it died on the highway and I almost crashed. Then on the 243 mile the car did the same thing, the last 2 times that did it, the car wouldn't start right away after it died. It took like five minutes for the car to start again, but it cranked, it just didn't start. I need help because it has become an unreliable car.
Thank you for your replies I just want to get to the bottom of this problem
As asked before, have you done the fuel filter? Checked the fuel pump? Could be the fuel pump is overheating and cutting fuel. But you will need to do some troubleshooting.
Fuel pump turns on with the key everytime, the 409 relay clicks everytime I put the key to start, even after it has shut down have not checked the fuel pressure, I checked the fuel pressure regulator and the diaphragm is not broken...tell me how to troubleshoot the fuel pump and I will do it. Also I have read that the throtle position sensor has to be calibrated, will that shut off the car sometimes?
I was driving today and when it was going to die everytime I pressed the gas it will backfire loud pop. (Before changing the fuel filter)
I would either make a new thread in the New Beetle section, or add to your current thread there about this. This section doesn't move much.
