A customer of mine bought a C3 Picasso 1.2 and the dealer said that they had chcked the timing belt thickness and that it was 'in spec' so didn't require replacement. Apparently the belts react with the oil.

I spoke to our regular dealer parts man who was very vague but did admit that they had replaced some engines under warranty as bits of the belt had worn off and they couldn't be sure where they they might end up.

Has anyone come across this issue? My wife has a C3 with the non-turbo Puretech and it's been a great car.
