Had a massive leak from the seal on my fuel filter. Apparently the VW design is bad and quite fiddly and it is very easy to fail to seal properly.

It's crazy considering the high pressures these fuel systems run at!

All fixed now though, good job I spotted it although I doubt diesel fuel is likely to ignite and send the car up in flames.
 
The filter isn't subject to particularly high pressures. It is upstream of the high pressure pump in the case of common rail engines and of the PD units themselves in PD engines.

What a surprise - a bad bit of design by VW !
 
Glad you got it sorted Obi, bad enough paying the current diesel prices without ditching the stuff for free all over the road ;)
