This has me puzzled, perhaps I can get some insight or maybe others have experienced this.
Fuel filters are supposedly changed anywhere from 35,000-50,000 kilometers and it's recommended.
I've been doing mine at every 40,000 for about the last year. My most recent change was met with some difficulty.
Seems this particular replacement filter did not want to get going even after pre-soaking with clean diesel. Long story short, the purge valve at the bottom wasn't 100% tightened up. Even with using slip lock pliers to snug up the purge valve, I still feel like that is a warning sign of a bad filter. Has anyone else had this experience?
Also, silly question, but there is another vehicle, a 2001 TDI owned by a friend. I don't think they have changed the filter since owning the vehicle. Theirs seems to idle perfectly and never gives any troubles. As the old addage goes "If it ain't broke don't fix it" . Or is that foolhearty thinking? Beyond maybe the odd losened micro contaminant that could be in the tank or fuel line, what else would be contributing to the mess inside the fuel filter? Is changing fuel filters that often really beneficial? Or should it only be done when certain symptoms crop up?
