Owner reviews for fuel filter

Changed it tonight. idles smooth again as before it was slightly rough.

Replaced the filter on my 1998 Opel Vectra and the stuff that poured out of the filter looked like used engine oil. Oddly enough the car ran fine despite that.

I changed the fuel filter, oops, that was a mess, but once I got all the air out of the system it's running great again.

The Mann filter isn't a cheap filter in a quality way. They make the OEM filter. It's the one you want

This is what mine looked like after being changed at a little over 200k miles.

I ended up replacing my brand new Bosch fuel filter with Wix filter from Oreillys and problems went away.

I really didn't think changing the fuel filter in my GLI would make much difference, particular seeing as the fuel inside the old filter looked perfectly fine. But wow, after a couple days, what a difference. I'd had some slowly-worsening issues with throttle response, particularly at low speed -- starting from a stop while engaging the clutch, or accelerating at low speed in gear. The car would bog a bit and then surge, unless I modulated the clutch and gave more throttle than I really should. Those problems immediately went away after the fuel filter change. This was at 55,000 miles. I think I'm going to have to start changing the fuel filter at about 40,000.

Fuel filter is interchangeable between many VW and Audi.

The original filter that came on my 2009 GLI was marked 6.4 bar. I believe the filter for the 2.5 Jetta is 4.0 bar, which is what Amazon tells you to get for your GTI too. I do believe that's wrong.

I replaced the "wrong" fuel filter with the fram replacement filter. i finally got the car to start and run at an idle. Runs rough at idle but really chokes out with any throttle at all.
