1991 Peugeot 405 - Answered Questions & Fixed issues

Most likely the ECU (Engine Computer Unit) is responding to some duff sensor / loose cable / whatever ..

All modern engines have more sensors than you can shake a stick at, some positioned in the most inaccessible places, that can cause the most obscure problems imaginable (remember the Oxygen Sensor in the Exhaust manifold that was 'poisioned' by some dufff supermarket petrol ??)

It's a Peugeot garage computerised diagnostics job I'm afraid...

did the head get resurfaced or planed

a haynes handbook,but i doubt it as a lot of immobilisers use the earth side of the relays to cut out engine and circuit diagram would make it too easy for the boy racers to half inch the jam jars.sort of classified info .sorry cant help

You've covered all the reasons why fan belts shred. I would suggest looking closer, and making sure the bearings are good in all belt driven devices.

Sounds like you have a blockage in your water system or your head gasket has blown. If the radiator is full then check the water to see if it is oily or check the oil to see if it is a grey colour as what you are describing is common when the water is not circulating through the internal radiator in the dashboard that air is pumped through to give you the warm air and the car is overheating quickly means the water is leaking into the engine somewhere. If the oil and water are fine then use a garden hose to flush out the water system heater hose.

maybe a fuse or a wire got disconnected from the guage

On this website you find fuse box description for Peugeot 405 http://www.autogenius.info/peugeot-405-1991-and-1992-fuse-box-diagram

do both sides flash fast or just one side ? if it's both sides you may wish to purchase a new flasher relay for your car. if it's fast on one side still... check further to see if there is a burnt out bulb including (if it has one the side marker light).

i would,nt have thought it would be a good thing to manually shift into first gear whilst going downhill, only use manual shifting from start off ,and overtaking but then the kickdown should be ok for that , not to be used as a brake , how steep is this hill ? i know this isn't what you asked but i dont think theres a problem with it not doing that

not sure about this model ,depends on year but removing fuse F! stop immobilisor from working

If you need the code check gumtree.com and search peugeot clarion radio code, they email code from your serial number! Quicker and cheaper than main dealer, I have used them!

You may need a car diagnostic tool, like Lexia-3 Interface, have a try!!! Original Chip Lexia 3 lexia3 V48 PP2000 V25 for Peugeot and Citroen with...

if you got the FOB really wet then the circuit board is ruined, you are going to have to replace it.

Normally, Peugeot's fuse boxes is one in engine bay. One is located and situated behind the driver's side lower facia panel. Remove the steering column cover and you would see the main fusebox.

Buy a Haynes workshop Manual of 607 or 406. They use the same 202 hdi disel engine.

check if any fuses are not blown out. To remove first remove +ve baterry terminal and then remove both the wire at the back of the cigaret lighter and ther will be a nut at the back just unscrew it, if no nut just press towarts outside.

There are timing marks on the pulleys. Make sure that you align all of these before attempting to replace the timing belt. If you are unsure of what you are doing, it is best to bring it to a mechanic. You might end up loosing your engine.

Top off coolant and re-test.
