Passat 2004 130 TDi: quite a racket coming from what sounds like the
fuel tank area. I'll have to get under it at the weekend and
investigate, but it sounds like the rear o/s area. If I boot it, it
goes away for a second or two and comes back. Car runs and drives
fine, no fuel issues.
Could this be the lift pump about to die?
