I have a Peugeot 206 XS 1.6 (1998 S REG).

For over 2 months now, the car has been randomly cutting out when
idling, for example at junctions or roundabouts. There appears to be no
pattern to when it cuts out, i.e. it cuts out in wet, dry, cold and warm
conditions. I have noticed that the rev counter often jumps and
occasionally sticks at somewhere around 3000 revs without me even
pressing the accelerator at all whilst waiting at a roundabout for
example. Also, whilst driving – the car occasionally kicks/jumps if I am
not applying much acceleration.

To begin with, I went to a Peugeot dealer garage. At this first visit, I
was charged £50 for them to inspect and clean the ‘Stepper Motor’ which
took 2 hours. After roughly a week of driving without cutting out during
which time I thought this had fixed the problem, the car started cutting
out all of a sudden (up to 5-6 times a day). Following this, I went back
to the Peugeot dealer and had a brand new stepper motor (idle control
valve system) fitted for £150, (on top of £50) which I was already to
look at and ‘clean’ the stepper motor on my first visit. Since then, the
Peugeot garage said ‘they had no idea what was causing it and could try
a number of different parts to try and find the problem, but obviously
this could cost me an enormous amount of money for just replacing
perfectly good parts until they find the correct one.’

I found this response very unsatisfactory so I decided to get a second
opinion and took it to a private garage somewhere else. Here, I was told
that the ‘Temperature Sensor’ was faulty and therefore this has been
replaced now. Needless to say, this still hasn’t fixed it.

This problem has caused be a lot of distress, time and money during the
last few weeks and I really need it sorted. I find it hard to believe
that Peugeot cannot even find what is wrong after having it twice to
look at!! I very much doubt I would buy another Peugeot or recommend one
to another person after all this hassle as this is not the first time I
have had problems with Peugeot cars.

Please let me know if anyone has had any similar problems and more
importantly and success in fixing such a problem!

Thanks in advance!
