I work in a shop in Wyoming, a customer brought in an Audi A4 3.0L TDI imported from Europe. Is there any websites/parts stores that I can get info and parts from.
It's in for 100k service so I need to know what fluids/filters it needs, if it needs a timing belt.
Any info would be greatly appreciated. Thank you.

 

Euro carparts are probably the biggest p, not sure if they ship to the states.
Carparts4less very cheap and good but not too sure about shipping.
You could always ring a UK Audi dealer who would be sure to help you with the parts you will need, I'm sure once you know what's required you will be able to source similar parts I. The US.
