Don't stop

Hello friends, my 2009 model 1.6 HDI model Peugeot is giving various faults such as exhaust emissions, oil pressure level and brake faults and it stalls when I touch the gas pedal (it doesn't happen all the time, sometimes repeatedly, sometimes once a month). It starts when I press the starter and everything drives normally. When I connect it to the computer, the above-mentioned faults appear. I have replaced the crankshaft switch, rail switch, fuel pump switch and fuel filter of my vehicle several times but my problem is not solved. While reading the forums, a friend of mine had a similar problem and wrote that it was fixed by replacing the fuse panel. Has anyone had a similar problem and what was the procedure you followed?

Peace be upon you. Sir, I have a 1.4 HDI 207. It stalls when driving or sometimes when stopped. It gives an exhaust emission faulty oil pressure warning. I haven't found a solution yet. Has your problem been resolved?
