Tdi - worsening fuel consumption

If it is the return line hoses, you wont pick it as a leak when the engine is warm as the fuel dribbles down the side of the head and evaporates.

I had the return lines do the same, twice, both times the last connection failed. It's not a very expensive part though.

damn is all i can say... i'm pushing to get 500km out of a 70l tank... granted it's tweaked and i'm a lead foot but geez :eek:

I have had my return lines do that too.

Could smell it but not see it generally when I opened I popped the bonnet when the engine was stopped but as Rick said once I opened it up with the engine idling I found it pretty quick.

I went to a Landrover dealer located in Artarmon (Sydney) and they in all seriousness tried to sell me pretty much an entire injector pump and assorted bits and pieces because they said they simply could not supply me with some appropriate hosing.

15 minutes at pirtek had it all sorted.

I couldn't get hoses at Pirtek that fitted tightly enough. I used them, but they eventually leaked back past the barb, so I have a hodge podge of hoses on there at the moment.

Just get the proper part, i paid $6 last time it was second hand but near new.

Having imported my D90 from the tropics, where mileage was good. I found milleage deteriorated by 30% and that the engine temperature never barelly rose above 1/4 up the dial. So I have this theory that the engine must run at midle of the temperature dial so that fuel air mixture combusts at the right temperature. I installed a new thermostat where there was none and found that performance has improved as did mileage.
