Has anyone had a CEL turn off? I have a 2000 2.7t and I went to the bank with the CEL on and when I came out and turned on my car it was off. Anyone else had this expierence.

yep not uncommon it could be the cold weather

 

mine comes on and goes off occasionally, when it was on i had the code ran and it came up a a cylinder #2 misfire. are you getting a rough idle at all??

 

Yeah its 70 right now so I don't think its the cold. Thanks for the help.

70 deg lucky sod its freezing here but that's normal for the UK if not freezing its raining, if the CEL goes of then that's not a problem occasional misfires cause this but a soft code should be stored for you to check it out

 

Mine will come about once every month or two and thengo off the next day (or after 5-8 starts). I have a vag-com and it gives me a code related to the MAF sensor but it normally comes on when the engine is cold. I took it too the dealer for this while it was still under warranty and they said that it might just be a loose connection to the harness on the MAF. I haven't really investigated it more recently. I seem to get the same code every time so I don't worry about it much. Can't recall the code number right now.

However, you should get your code checked to see if it might be something different.

 

70! Damn, the high here today is 11 degrees!

 

I have a O2 sensor heater malfunction that will clear itself. For the record, I have a 2001 2.7T allroad.
The code 0135, also does not lock it. I just went to get the car inspected and DMV did not get the code.
The next day the CEL was back on,
It is now off.
