... you're not gonna get a lot of response WRT an '88 urQ from the 
colonies :) :(

My '83 has about 140K and a filter/trap/whatever.  I think that Audi calls 
it a fuel filter because I think that it is exactly that ... a fuel filter 
from a low fuel pressure carburetted car.  Audi must have gotten a real 
deal on these things, because the same filter is recommended as an oil 
trap for the vacuum system on the 5k/200 climate control!

I will always keep one in line no matter what anyone says about removing 
it.  That filter will keep chunks from getting to the fuel pump ... cheap
insurance IMHO!

HTH!
