WHY DOES indicator stalk on Peugeot 406 KEEP ON FLASHING?
yyyHaving had the same problem myself, and done a lot of
research, the answer is that there is a known design fault with 406
(and some 306) indicator stalks that leads to random flashing. The
original part manufacturer went bust because they couldn't cope
with all the warranty replacements.
Peugeot will replace it if the car is in warranty and even out of
warranty on a case by case basis. If you get your car serviced by a
dealer then they might replace it out of warranty to keep your
business. Most people don't realise that consumer law requires all
goods to be fit for purpose and withstand reasonable wear and tear
- irrespective of warranty period. You don't hear of other
manufacturer's indicator stalks packing up after 3 or 4 years from
I managed to keep mine going for quite a while by wiggling the
stalk vigourously up / down / back & front for a minute or two
- make sure the ignition is off.
I think the problem is that the internal switch parts wear and the
switch contacts touch when they shouldn't. I looked at taking mine
apart, but it's not made for servicing. Dealers charge around £70
for a new stalk but you can get them for £40 or less. They are easy
to fit if you are basically competent in DIY. Just find the screws
under the steering column bottom cover and remove the top cover.
The stalk is held in by a couple of screws and there is a push fit
connector for the cable.
