406 1.8 1996 faulty display

Hey all,

I have a 1996 406 1.8 and am experiencing faulty display (speedometer, rev
counter and fuel-gauge). Temp-meter is apparently working fine. The
speedometer sometimes just drops down to zero and only works again after
giving a gentle knock on the display. The fuel-gauge is all over the place,
one moment reading half and the next one reading full. I had the complete
display replaced but didn't want to go for a new one because of the high
costs. The replaced display now has just about the same problems ! Ofcourse
the peugeot-garage will sort it out but they say many 406's have faulty
displays and so chances are another 2ndhand display will have the same
probs. So it's either living with that or paying the full amount for a new
display

A question. Is there anything else that might cause these problems that you
guys might know of ? Appreciate any help you could give me, many thanks in
advance.

 

Was having the same problems.
There were a lot of loose contacts on the print behind the meters.
Sololution : resolder the loose contacts on the print.

Thanks. Yeah the garage tried that but encountered too much problems and
decided to change the complete display instead.

 

It is better to bring it to an electronics repairshop...

I'll second that,I'm an electronic engineer[retired] and I get a lot
of work from garages.they cannnot do the fine soldering,and more
importantly,circuit checking that I can and do.
I was recently asked to repair a Jaguar unit,price at the dealers?1500
pounds! I don't have the equipment now to check that kind of unit but
it's still a rip off at that price.Take it too an electronic
engineer.regards

 

I would second this. As an electronics engineer the last person I would
trust electronics to is a car sparkie or mechanic. They may be able to
change complete components but they have no training in electronic fault
finding or the skills to do this work. Their usual mode of operation is
either to use the makers fault finding guide often POOR or keep changing
components until the fault goes away.
I have repaired many car devices for a cost of a few pence as opposed to
hundreds for the new manufacturers new component.

Thanks all for the help. I'll take the display to an electronics shop and
see what they can make of it.
