put an additional petrol pump in the fuel line ,they cost about150€ from the bosch agent ,connect in line and splice the feed from the pump in the tank ,that will cure it ,these cars suffer from a dodgy connection in the feed wires to the pump in the tank,they corrode and get hot in the connector head of the unit .An additional pump releaves some of the load and will keep it going evan if the one in the tank plays up .

I need the manual for the interior. so know what all the buttons and switches do for the 406

You need an owner's manual. Of course your Peugeot dealer can get you one for a price. A search of Google with the term "Peugeot 405 Owner's Manual" will bring up many sources for a free download of the owner's manual.

Maximum speed and fuel consumption

What you have is simple. The vehicle's computer only allows the vehicle to reach up to 95mph. as a safety feature. If you're racing it, you will need to get ahold of an OBD 2 linkable program to change your maximum vehicle speed.

Vibration at 2100 rpm

It is probably your Motor Mounts. They attach the engine in 4 places to the frame of the car. When the rubber wears out, it will cause excessive veibration.

Take it to your mechanic and tell him to check the motor mounts. For the front and side three mounts, it will probably run about $550 with the parts, im guessing.
