Might be one you ignore. I'd have to see a log of it coming up, though.

Is there any new information on this. Iíve had this code ever since my tune. Itís been happening everyday now within the first few minutes of driving. Once cleared itís usually gone through the remainder of the drive.
Car runs fine, just annoying.

For the people that throw this code, reasons can be different, itís really case by case.

Default 29f1 code - first start up - 01-06-2019, 01:12 AM

I am getting a 29f1 code. It is also my first start up with my ST. My car will run for 30 seconds and then shut off with the cooling fan speed high and running.

During the build we replaced LPFP with a Stage 3 from Fuel-IT. Thought that I should mention this since it is a fuel pressure problem.

Any help with this code would be greatly appreciated!

Did either of you figure out what this was? Having the same issue after a ST install on first start up.

I've had the same issue happen numerous times when I start the car. From a cold start it will essentially go into limp mode, idle changes, fans kick on, and the engine with the slash comes on. I've turned the car off and restarted it with no issues. Very intermittent! I've got a Stage 2 Bucketless LPFP installed but these symptoms began well over a year after the install of the LPFP.

Unfortunately since this happens at start up and its intermittence I have no logs to back this.

Has anyone have any theories on this?
