406 HDI BRAKE FLUID WARNING MESSAGE DISPLAY

Just to thank the group for the suggestion that changing the hand brake
switch may cure the
problem of the 'brake fluid warning message' appearing for no apparent
reason.

Obviously, I first checked the fluid level itself which was fine. I
then presumed a problem with
the fluid level switch, disconnected it/shorted it, which again had no
effect.

Fortunately, I then looked on the forum, which suggested the hand brake
switch change.
Like everyone else, I was skeptical and couldnt see the relationship,
but for the sake of a ten minute job and £2.65 from the local Peugeot
Dealer I gave it a try....Problem Solved!!!

Prior to changing the switch I had wondered whether the computer was
looking at different
resistances in the message circuits and somehow the brake switch had
developed a high resistance which was triggering the faulty message.
On changing the switch, I did indeed measure a high resistance across
the switch while in its 'open' condition which seems to go along with
my presumption of how the computer reads
its message circuits.

By the way, when I went to purchase the switch and explained why I was
replacing it, the dealer went to great lengths to explain I was
changing the 'wrong' switch.Fortunately this advise was
ignored...........THANKS AGAIN TO THE GROUP

Did the dealer go into detail? which switch did he/she say you should be
changing?

Hi Rob. No he didnt go into any detail, but could only say that as far
as he was concerned, the hand brake switch had nothing to do with the
low brake fluid level warning.
He suggested changing the brake fluid resavoir switch, which I had
allready tested and knew to be OK.

 

Good dealer you have there! It is a very well known fault and every
dealer should know about it.

 

But why does it matter to a dealer, standard procedure these days seems to
be change everything in sight until fault goes away, after all, it's the
punter who pays, and there is profit to be made on every part.
Fortunately, not ALL dealers are like this, you just have to look carefully.

Hiya Dspark.
Mine has this problem, I'd already figured it was something to do with the
handbrake switch as only ever does it with the handbrake on and the levels
are fine.
(After initialy checking them two or three times.)
Is it a big job getting to the switch to swap it?
Where abouts is it located?

regards.

It's under the centre console at the base of the handbrake lever. Bit
of a palaver to get to but not too bad and should take no more than
half an hour.

 

Many thanks.
