HPFP Problem?
I have been having problems when going WOT in 3rd and 4th Gears.
Started out with shuddering and misfires, now have more heavy jolt and limp mode triggered. The symptoms are most pronounced when getting on the throttle hard - particularly after changing gear. There are no codes raised! I did a few logs and Terry mentionned that the fuel pressure dropped off the chart. Is this likely to be the HPFP/LPFP or could it be faulty injectors etc? I have changed the sparks and coils, cleaned the VANOS solenoids and MAP sensors. I'm gonna replace the fuel pump and clean the intake valves next - unless anyone disagrees?!

seems impossible no codes are thrown. You have the auto code clearing off?

The only code raised is 3100 low boost mode engaged. I.e. an 'effect' rather than a cause.

i dont think is possible to get 3100 code without the one that actually caused it.

I got these codes a few weeks ago.
29F4 Catalytic converter conversion 29F5 Catalytic converter conversion 2 2D18 manipulation cover, maximum air mass 2F71 E-box-fan, input signal 3100 low boost mode engaged -- CEL displayed 0000 Failure location not implemented But Terry didnt think any of those codes would cause a limp.. Ps. Problem is there on Map zero.
