Hi I was dirving home with a trailer yesterday and I found that I had significantly less power than usual. Vehicle is a 96 300Tdi Disco SerI.
After recent posts, I suspected in no particular order:
The lift Pump - I am not convinced mine is working at the last time I changed the fuel filter, it did not seem to do anything. The sedimenter thingy at the back near the fuel tank- I have never looked at it. The air-inlet elbow collasping - although I thought this would result in almost total power loss, and I would say I pobably still had about 50-60%.
I had a quick look under the bonnet and saw that the long pipe that runs from the 90 elbow, past the suspension tower, into the charge cooler seems to be pretty rough around the suspension tower. I have not yet removed it but would a crack in this pipe cause the sort of power loss I mention?
I have recently had the engine redone and there was no sign of overheating or loosing fuilds, so I am pretty sure it is not a head gasket or similar.
Regards Stepen
