So I'm wandering if my car is in limp mode. Why? Well the check engine light is on and she idles fine for a minute or two, then completely drops fuel pressure and dies. If this is not limp mode then what is causing this? I just replaced all for injectors, believing that this was the original cause for it not running right i.e. rough idle, fluctuating fuel pressure before it completely drops and dies. I've also done the general maintenance as well like change oil, flush and change both radiator and heat exchanger, replace h spark plugs and also the battery. I have replaced the fuel pump, filter, and now injectors. She idles fine now, like a dream then given a minute or two drops pressure and dies. Also she's running really rich, so much in fact, you can smell the extra fuel that's being dumped to compensate. Can anyone tell me what's going on, or what it is I'm doing wrong here, cause I'm lost, frustrated beyond belief, and almost fed up with the whole thing.

I never would have imagined that an o2 sensor or an engine coolant temp sensor signal whould be the reason my car doesnt stay running. How or why exactly is that? That is code 5 and code 4 or should I be looking at code 54? I might just work all three three just to be safe because I looked up symptoms of each code and how they corrdinate with my car and each one is pretty spot on with what my car is doing.

I might start by replacing the O2 sensor (as long as you're sure your wiring harness is good). Coolant temp sensor I believe you would see the failure of this via the temperature gauge on your console. What is that doing? VWs will basically always tell you its cold when it fails even when the motor is warm. But O2 sensors can be cheap and easy, I'd start there |
