Yes, another post about a Restricted Performance message, with a red triangle. I used my IID to check the fault, which was "Low Boost", however I stupidly did not record the code. I didn't record the code because I was sure the fault would re-occur. Trouble is, this was months ago and the fault has not re-occurred.

The Restricted Performance message and red triangle appeared just after a lunch break while on a very gentle tour through some 2wd tracks around Gembrook. When I say gentle, we were driving at about 40km/h on flat smooth gravel roads with no hills. I've since tried to trigger the fault by placing the engine under load & high revs but no faults occurred at all. I have checked for signs of cracked manifolds and visually checked intake pipes etc but nothing is obvious.

Any suggestions on specifically what to check for a "low boost" code with Restricted Performance message? I'm planning a Simpson desert trip in May and don't want to be stuck. Thanks.
