Good evening all.

Just looking under the bonnet of my D4 4.2 tdi looking at the serpentine belt with a view to change when I replace my A/C compressor (another story).

I noticed that the High Pressure Fuel Pump is driven by a toothed belt. This is all news to me. Anyhow, I presume this has a replacement interval and was wondering what it might be in terms of time/mileage. Is anyone able to enlighten me and is it an absolute pig to do? It certainly looks to be given its location at the rear of the engine.

Cheers, Steve
