Car Forum / Peugeot Cars / August 2007Pug 406 HDi 2001 Exec - Electrical Gremlins are breeding
Our 2001 406 exec has started to display some worrying symptoms. Posted last week about indicator problems. Now the thing beeps at you, the engine management light came on and things went from bad to worse: 1 Rev counter drops to zero revs whilst maintaining constanst speed 2 Speedo arm 'waggles' up and down 3 Odometer trips out and sets total milage back to zero (shouldn't complain, but it does reset itself!) 4 Indicators cease to function at all 5 When turning off headlights dash, remains illuminated It did this on Friday night, stopped car repeatedly, switched off left for a few seconds and it seemed to reset itself. Drive on slightly further and it started again. Mechanically the car drives as well as ever no effect on engine or progress at all. Took it to a mechanic on Saturday morning and he looked at the wiring behind the dash and under the steering wheel. He couldn't however interogate the diagnostics as he said the thing didn't have a live feed to it. Also the steering column stereo controls haven't functioned since we've owned the car. But since friday night (touch wood) it hasn't reoccurred since. Maybe a loose connection, blown fuse, ecu shot to bits? Have any of you guys had this or similar problems? Is it something I can leave for now or would you recommend a full check over by an Auto Electrician as I guess not having the diagnsotics working is quite a handicap. Bloody car, christmas less than a week away and we're trying to buy a house in the new year, guess what we really didn't bank on?! Thanks in advance for advice and merry chrimbo. sounds like an earth problem. Andy > Our 2001 406 exec has started to display some worrying symptoms. Posted > last week about indicator problems.

Or even when the battery terminal connections are not all they should be. Worth checking them. Kinder than hitting them with a large hammer which has also been known to work sometimes - the other times it just knocks the post off the battery. Ron Robinson Hi, I'm experiencing the same problem with my 1999 Peugeot 306. Did you ever find the cause of that erratic behaviour?

The 306 is usually caused by a corroded snapped earth lead (from chassis to engine) >Our 2001 406 exec has started to display some worrying symptoms. Posted >last week about indicator problems.

Thanks Mark, I'll have them check the electricals again. So far the battery has been swapped, terminals cleaned and fuses checked. To answer your question, yes, both the temperature and fuel gauges read 0 while the speedometer and tachometer reflect high readings and the mileage display goes blank. The car also beeps 5 times when I take the key out of the ignition. Thanks again, Janine >>Our 2001 406 exec has started to display some worrying symptoms.

I have a pug 406 HDi 110 estate V reg. The wipers seem to have a mind of there own? They keep stopping. On fast wipe it will do about 15 wipes then just stop anywhere in the screen. The slower speed wipe was doing less wipes and stopping (9ish)but now seems to keep on going. I checked the column stalk switch and sprayed it with contact cleaner but to no avail. Then went hunting for the relay and ended up taking the black box out and opening it up. I thought there "may have been signs of moisture ingress (some white corrosion like dust on back of circuit board) so cleaned is with brush and circuit board cleaner spray and left it to dry on the living room radiator. No better. Next I went to the scrappy and fished the black box out of an earlier (R reg I think) 406 petrol and tried it in my car to see it the wipers would work. Nothing worked!?! Oh well it was worth a try I said to myself. Now I am saying to myself it was not worth the darn try because even with my original black box in my car has gained 12000 miles on the milometer. DRAT and double DRAT. I have lifted the carpet on the drivers side and found moisture so will leave it up until it is all nice and dry. So my question is 1/ what do you think is the cause of the wiper problem and what needs to be done to fix it. 2/ how can I get my old mileage back? >>Our 2001 406 exec has started to display some worrying symptoms.
