Hey all,

So i had a couple limp modes 3 weeks back...2 times to be exact...a couple hours apart from each other.

I had a friend plug into my car and run diagnostics with ISTA+\

Can anyone here with more experience provide any additional insight on what might have caused these issues and if there is anything I should be doing? Like would I need to go into the dealer to get something replaced?

DME 11A002 - Fuel high pressure, plausibility: Pressure too low
Fault Description: Diagnosis monitors the high pressure fuel system. Fault Monitoring Conditions: The fault is recognized when the rail pressure is below the setpoint value
SAE Fault Code: P0087

DME 101F01 - Intake pipe absolute pressure, plausibility: Pressure too high
Fault Description: The diagnosis monotirs the plausible position of the throttle valve in relation to the applied intake pipe vacuum. Fault monitoring conditions: The fault is recognized when the monitored mass flow rate rises above the limit value
SAE Fault Code: P112E

I'm hitting up a track day tomorrow. Wondering if i should maybe remove my BMS intake and put the stock one back in for this event (based on the second fault code?).

With regards to my mods, the only two things I have done are BMS Stage 1 and BMS Intake (stock I do have MPPK and MPE though). Maybe I should remove my tune as well? I'm guessing taking the boost down even a notch will help with some heating issues?

And if i haven't done anything to fix the problems above since they happened (my car has been running just fine otherwise ever since), would putting myself in a position like being at a track day cause these issues to come up yet again? Am I going to have a really short track day tomorrow? haha

Thanks in advance!

Look at the freeze frame for the fuel pressure code specifically the rpm and occurance count.


Could be a problem. The other code I think is from JB4 not the intake.

DME 101F01 Details

Oddly looks like there have been quite a few occurrences.
The one at the top at mileage 13177km is the one im referring to for the first limp mode I received last week.

I never received any sort of issues or limp mode with any of the other occurrences. Is that normal?

I usually try to shift around 5500-5800 RPM but clearly in a a couple of these occurrences I accidentally let it rev higher than I'd like to...Still learning this track!

I've just started getting this error: DME 101F01 - Intake pipe absolute pressure, plausibility: Pressure too high

What was your resolution and cause. I don't get limp mode and after a day or two the CEL turns itself off.
