First LIMP MODE..

eseng · 09-26-2010, 10:59 PM

Got my first LIMP MODE this morning while driving to work. Occurred when i downshifted from 6 to 4 and rev passed 5000 rpms. Got the half engine light and no boost. i was still able to cruise 80 mph but was hard keeping it there.

After i shut off the car and turned it back on, the half engine light went away. i tried to reproduce the trigger but have not gotten another limp...

Car is basically stock right now, except mufflers. i was waiting for my warranty to end before i put on any of my mods. Car currently has 41000 miles. no long cranks really...usually only takes a few seconds to turn over...so i dont think its the HPFP.

Anybody know what can be wrong? i just ordered a BT Tool today so i don't have any codes to give details on.

Get used to it.

Well these cars shouldnt take more then a 1/2 second to start.

So it very well could be HPFP, however, it sounds like its under warranty maybe still? Bring it in?

warranty ends next month...i guess i should just bring it in..the code should still be stored in the ECU?

The newer software seems to take longer to fire up, 1-3 seconds. Could be a boost leak, misfire, as well as the HPFP. Get it check out. I was at the track this weekend and got a limp, turned out to be a Cylinder Switch Off fault.

36.xx + I think I'm on the latest one now (37.xx) needless to say, they have been longer for the last few updates over a 6 month span.
