BSI BRAIN FAULT

My name is Salih, I just joined you. I have a 2006 model 307 SW. At 95000 km and when I received my Warning lamp was on and Gearbox Fault was written. I did not care that I would change the gearbox valves and oil as well. All kinds of maintenance have been done in my vehicle for now. But the service alert lamp with exclamation point in this triangle does not go out. Peugeot master (two different masters) with service experience stated that the problem may originate from the brain. As a matter of fact, even though the fault is cleared, it is still lit on the screen. When the ignition is turned off and the door is locked, only one goes out.

In the last maintenance in the vehicle; Spark plug, ignition coil, oil, filters, transmission oil and valves, etc. maintenance was done. It's not in a non-working option.

What do you think this might be? Are there any brain repairers?

I am waiting for friends who can give help and suggestions.

I saw that the accelerator pedal sensor plus the short-circuit error on the end was written.

Error code P1644 Fuel pump speed control circuit malfunction.

English: Fuel pump speed control circuit malfunction

Do you have any friends with knowledge on this subject?

It was checked if the vehicle was replaced by the throat butterfly, the accelerator pedal and whether the error was deleted. In the ongoing error, the sockets were checked one by one. The error persists. It was diagnosed that the error is related to the Brain. I already sold my car in a way that the brain was repaired. Alan was going to have a friend repair. The company that does this job says it will cost around 500 TL
