Peugeot and Citroen springs again.
Earlier in these posts I refer to the way some peugeots and citroens have a habit of shredding their front tyres when a coil spring breaks, mentioning a modification made under recall by the manufacturers consisting of a retaining shroud fitted around the base of the coil spring seat.
The above is an example of the retaining shroud in place, what cannot be seen in this instance is that the coil spring has broken and that the shroud has done its job and prevented the broken end of the spring falling down and shredding the tyre. The following image clearly shows how the spring has broken but remains securely on the spring seat. 
I should also mention that I have seen a broken spring that has managed to slip through the base of the shroud, so it seems it is not always successful in retaining the broken spring in place.
please note that Peugeot do NOT (at this time, February 2012) fit the spring catcher, though I believe Citroen do on some models.
see my page http://tinyurl.com/6q4tmw5 to see what happened to the car my wife was driving with our 4 year old grandchild.
Peugeot are presently denying there are any safety implications caused by sudden tyre deflation when a spring breaks.
