I did wonder about skimming - but these disks are being replaced by
my local Peugeot dealer in St Albans, who have serviced the car since

which case Peugeot have a significant problem to sort out - I spoke
to Peugeot customer service today but they were not able to tell me
if any other motorists had reported problems here.
