RE: Fuel filter intervals on Audi 4000

I used to do it every 30-50K on the 4000 but let it go for 100k the last
time (got it changed as the pump was getting noisy). Probably depends on the
quality of gas you have. The fuel system in the 5000 seems to be pickier so I
have this done more often.

Hi, I was wondering if anyone knows the recommended maintenence interval
for the fuel filter element on a 4000s with CIS-E injection. When
I asked a dealer several years ago I was told it was a "lifetime"
element, others have said change it every 30k miles. I have been
doing it every 30-50K, what to others do on their 4000 or 5000?

BTW, I just got done with this job and it was a bitch this time.
Installed two differnt filters and they both had defects in them.
First was a Hastings filer (made in Germany) that has what I would
consider a design defect ( e-mail if you really want details on it)
and second was a Bosch (made in Spain) which had a manufacturing defect. 
The third time with a new Bosch filter was the charm. I
recommend Bosch over the Hastings filter and surprisingly it was
cheaper (~$24). Just an opinion
