Maxi, cheers, thanks for your kind words. I was feeling a bit miffed because I'd noticed several weeks ago looking for stuff for the 500 that the breather pipe issue appears to have been a problem.
I've also now seen via searches on this forum, that this subject has raised its ugly head a few months back and the consensus by some forum members back then was, don't bother going to the dealer to get it fixed, save the fuel going there and sort it out yourself.
I personally don't agree with that particular sentiment if the car is under warranty and I would always suggest taking the dealership to task for original manufacturer faults. Certainly, if I do find that our own breather pipe is original defective stock, I will take it up with my own local Fiat dealer when it goes in for its first service end of next February unless of course it splits in the meantime!
