Ive recently purchased a Citroen C5 Diesel Estate, (heavily discounted
managers special !!!!!)
it  now has 250 mile on the clock ive driven only short distances over
the last week.

On a couple of occasions when leaving the car after driving ive noticed
a light burning smell. ive assumed as all is new there must be some oil
or grease say on the exhaust being burnt off.

Today (Tuesday 27th Dec 05) something strange happend. ## a cold day 2
degrees centigrade indicated on the dash##  I drove 5 mile and parked
up to shop, and noticed a roaring sound as i opened the car door, the
main radiator fan was going full belt and there was a VERY VERY strong
electrical burning smell. I lifted the bonnet but could see nothing.
Got back in the car started it, checked the engine temperature the
needle pointing to straight down "6 oclock position" Normal, but still
a strong burning smell. I turned the engine off but the fan was still
going full belt, the burning smell now seems to have gone, I decided to
drive along to the citroen garage 3 mile away, all the time the fan
still running fast, when i got there the garage was closed so returned
back to the car park where i had started, the fan still going. I got
out of the car locked it but the fan was still going strong (bear in
mind it is 2 Deg C outside and i have not been stuck in traffic and the
engine temperature needle indicates the engine is normal, SO WHY IS THE
FAN RUNNING). Worried that with the engine off and the fan running the
battery would flatten i started the car and sat in it, I ran through
the Diagnostic check accessable from the control panel, it showed no
faults and passed whatever checks it does. After say 3 minutes then the
fan stopped.

I have driven the car for short journeys since without problem.

It is possible the smell was brought to my attention because the fan
was running and therefore directing the smell towards me i would have
otherwise not noticed the smell assuming the smell is nothing to worry
about.
But why was the fan running on a very cold day when the car has just
driven continuosly a couple of mile at 30 mph barring one stop a
traffic lights. And continue to run for nearly 15 minutes.

Im looking for advice of similar experiences please

Thank you
