can anyone help with diagnostic on old 406?

Talk about the 406's electrical system, what wires do what, how to add extra functionality, etc.

hi i just needed to vent there before i exploded!after all that the 2nd lamp turned up,broken!obviously broken before it was packed as the entire bottom plastic mounting point is broken of and not in the box so back to square 1 looking for right headlamp for n/s,i guess its the price we pay for doing it ourselves and not paying the robbers to do it,nearly there though a small miracle in itself as she passed the emmissions test no problem this time just showing that the previous mot station failed to run it up to temperature before doing the test which they get away with by bypassing the oil temp probe on the analyser a right con imo and allmost all older cars are sure to fail unless there at running temp and i wonder how many folks get sold a new cat or ecu lambda etc which they didnt really need?
its funny because im an old hairy hippy type and they take one look at me and think i dont know about cars anyway im getting there a bit at a time and will be jolly glad when im done,thanks and pm will be along shortly.mark

well in the continuing adventures of duke mends headlamps it turns out the seller has no other lamp in stock to replace the broken one and has refunded my money leaving me without a lamp for the n/s so i decided in my wisdom (or not) to take the new but broken lamp and the old but unbroken lamp and build 1 good working lamp from the 2,cant be that hard i thought so i have spent this morning with a combo of tensol acrylic adhesive and a hot melt glue gun using the bracket from the old worn out lamp which was easy removed using a red hot stanley knife and a blowtorch i then carefully cleaned and scored the plastic on both pieces and used tensol and masking tape to hold in correct position till tensol drys about 6 hours and then had the problem of fitting headlamp adjuster correctly as this lamp unit came without the springs that are meant to hold the reflector steady till you fit the adjuster making fitting a bit harder but with a combo of very skinny fingers through the bulb hole and the spring from the o/s lamp i managed to fit it and it seems to be holding ok.
i know most folk probably think im a bit mad bothering and tbh there right but it took me ages to find the lamps at a price my minute budget allows and have learned to be resourceful when needed which atm is all the time but i now,touchwood should have 2 headlamps that fit the car and only cost me £50 and a few hours of my time,back later with some pics maybe,peace

hi jon the breakers only had lamps nearly as worn out as the old ones and as the old girl passed the emissions test and the money i not had to spend on bits for the engine have been spent on new lamps i got a small budget but i think sometimes its easier to change than mend,but only once i have attempted to mend it first!but its booked for retest wed so should be legal again soon,take care

well just got back from the retest,passed but despite 2 new headlamps and bulbs the headlamp leveler on the n/s doesnt work but i think its the motor bit and as they passed now i just wont use the switch i didnt even know was there until the mot tester showed me!i learned where the fog light switch was on the last mot as well!they did charge me £15 to do the headlamp aiming but i degrudge spending a penny on a job i can do myself but since ive no beam setter i had no choice but it did make me feel better hearing other customers bills for mot work in hundreds of pounds all in less than £130 not to bad for a 20 year old pug,of the southend in it to pick my grandkids up tomorrow i do hope that dartford crossing behaves!peace

hi all well after reading most of this and other forums on these petrol 406s i changed the 2 water temp senders imo a strange arrangment but for once both came and fitted and today she started a bit smoother and seems happier but until the lead comes and i can get her on a diagnostic the tickover is to low unless i put the lights on then it sits at 1000rpm without drops down esp when cold to 750rpm and then stalls so im hoping this just means the new stepper motor now needs setting to correct number of steps for the car so,a new ecu,new coil pack,every sensor on the engine other than tps new exhaust,cat,clutch,clutch cable,front brakes,rear w/cyls,and full service including the fuel filter and tank filter,anything ive missed? :lol: i will tell how she runs later but the engine is smooth now no longer shaking about on tick over,peace

Hi Duke,
Don't wish to state the obvious but have you cleaned the throttle body with a tooth brush & some carb cleaner ?
These allways get gummed up, mainly with the oil mist in the air intake due to the engine breather system :roll:
In my 28 years experience of working on petrol engined car's, if they've got a low tick over this has been the cause :wink:
Got to be worth a try, a few minutes & a five pound tin of carb cleaner :D
Hope this helps DDD :cheesy:

hi yes i have given the entire throttle housing a good clean out and its all spotless even all the breather pipes are clean and good nick i also fitted a set of injectors i was very lucky to get cheap from a peugeot dealers going out of bussiness complete set with all new seals and all carefully fitted myself and i have checked also for induction leaks of which there are none but tbh other than stalling when shes cold she drives super now and i believe the fault all along may well have been the water temp sensor for the ecu as she seems far happier since i changed that,just awaiting arrival of the com lead and hope setting stepper motor will cure the cold stalling,thanks for your input.
