[Resolved] Out of gas in turn

[flav]

Hi all,

Ive a weird problem only when I have less than half of tank.

In a middle of a big turn with some speed (3th gear 90kmh), it's like the engine completely stops (it is as if I release the gas pedal or
out of gas). And at the end of the turn, all is back to normal.

I tried to get some data from OBD :


We can see that when there is a problem, the stft1 increase a lot compared to a normal turn :


I checked the gas pomp to see if there is any visible defect but nothing strange.

If someone has an idea

Found the issue !

The bottom part of the fuel pump module on my car is not complete compared to another twingo RS.

Complete :



Not complete


This red/orange valve is responsible of keeping the fuel pump feeded with fuel even in some weird situations. It keeps a fuel cache in the bottom white plastic part.
