Hi Guys, does anybody know what are the cause for limp mode that wont throw the cell light, I am aware of the air flow meter wont throw the cell but I have a new one so its not that, no air leeks, new plugs, its not the coil pack.
Will the crank/cam sensors cause limp mode without the cell light coming on? after an ecu reset the car run and picks up very well runs on full boost etc, then after some spirited driving goes back into limp mode, I have no Det either so its not that.
Im sure this has happened to another scooby so any advice guys.

 

If Limp home mode is activated the CEL light should be illuminated surely?

 

Any ideas?
