Where to buy a new dipstick for S3?

[coreythorny]

My dipstick has perished and broken around the O-ring, seems to be a common problem!

nicely for me this happened last week on my 21st coming home from the restaurant as I topped up my oil with the warning light came on and the broken bit fell into the dipstick tube! It's all getting cleaned out Wednesday.

My local dealers aren't exactly local, infact quite a trek! I just wondered if anyone knew anywhere online or if anyone on here sells them?

Thanks.
