Pb start 406

Hello
I made the acquirement a few months ago of a 406
It sometimes arrives that the motor doesn't want to start without obvious
reason
Agents Peugeot don't find anything
One only said to me that maybe the padlock could be in reason, but without
other explanation.

One among you would have him knowledge of this kind of problem and how
to solve it?
By advance thank you for your suggestions and advice.

Cordially.

Hi JR
Find the fan motor, check the black wire, (earth) and the red wire
connectors, sometimes they get hot and cause bad connections,

Hmmm, or could he mean the engine doesn't start, and the dealer is
suggesting that the immobiliser is faulty. And if it is intermittent,
it could be the aeriel around the ignition lock. Maybe if Jacques
could repost in French and GT could give us a quick translation??

 

I agree,,, come on GT

Hi nigel

Thanks for explications, but what is aeriel? and GT ?
Cordially

Jacques

 

Hi Fitzy

Thanks for the advice, but I'm sorry, I don't understand the report between
the fan and the no-start.
Explain me if you please
Thank you again.

Hi,

They're talking about the transponder's aerial, which is around the Neiman.
And I am GT

Ils parlent de l'antenne du transpondeur, qui est autour du Neiman.

Hi,

Just found it on another NG, yeah that's it : engine not starting,
intermittent fault.
When he brings the car to a Pug dealer they don't find anything, as the car
works. One of them told him this could come from the steal-lock, but with no
further explaination.

Could be the transponder aerial, but I have another (far more vicious, hence
I prefer this) : neiman's contacts worn out. I guess it's almost the same
wiring than on Xantia's, and it's a common fault with A/C, as the aircon
wiring goes thru the lock.
Almost the same than on "big engine powered" 205s (GTi / D / TD) with heavy
mileage (but it was starter motor-related), if you see what I mean.

mais my english is bad.

I seem to remember that there was mention a while back of ignition keys
becoming very hot when the fan was running on the 406. Is there a clue here
somewhere?

I had the switch on the back of my ignition lock (1998 406) swapped about 2
1/2 years ago as the aux contacts had burnt out. It started losing the fan
again occasionally about 6 months ago, and is getting worse. I reckon its
burnt out again. It does seem a weakness on these!

 

Salut,

OK.
Antidémarrage à clavier ou à transpondeur ?

Je t'en prie.

Bah c'est pas grave, on arrive tjs à se débrouiller... Vrai que le forum
français, j'y passe pas svt non plus.

Hi to all

Thank you for all your explanations, now I understood the 2 uncertain
breakdown possibilities and, I am going to ask the mechanics to verify the
transpondeur and possibly the contacts of Neiman.

Thank you again

Hi,

Possibly, not sure about that, though.

Hi,

Yeah, and I'm surprised, as there doesn't seem to be any official mod / fix.
I imagine fitting a relay would be a cost-effective & easy fix.

The official fix is to sell you a new ignition switch ever 2 years!

 

I posted about the key getting hot. After some experimenting by Nigel, and
comments from others who experienced the same thing, we concluded that it
was because the blower motor draws its power through the ignition switch.
Certainly it only happens when the blower is in continuous use (such as the
current heatwave). Mine is a '99 model, later ones may be different.
