I wish I'd read this before Friday.
Checking the oil after work (engine last used 9 hour previous), I put the dip-stick back in to hear that fateful 'crack' as it hit the first bend, just thinking it was the noise of it knocking the guide tube, but didn't realise until it was too late that I'd snapped the end off. A nervous journey home and I'm glad to read that it's not a problem to have a broken bit of plastic in there.
Does anybody know how to get it out or is this best done when serviced? Mine has about 3500 miles to go so I'm planning to do it early September but will bring it forward if necessary...
Also, looking at the dip stick closely I'd like to meet the inventor in a dark alley and give him the benefit of my opinion...
