Typsey Posted January 1, 2006 Share Posted January 1, 2006 Coupled with the problems I have had recently with the landy(cooling), she has been returning aroudn 27 mpg which is around 10% less than normal. This has been going on for some time now but I haven't noticed any difference in engine noise, roughness or pulling power. She seems to be driving fine, but, the fuel lines from pump to injectors are smelling quite a lot of diesel. Cannot remember if this has always been the case, but she's in for servicing on Thursday and was wondering if there is a modified line kit available or if I should just have the LR ones replaced with like? Any ideas? Quote Link to comment Share on other sites More sharing options...
muddyplugger Posted January 1, 2006 Share Posted January 1, 2006 I would have thought you would need to loose a lot of diesel to make that sort of impact! How about parking over a puddle for an hour and watching for any nice rainbow colours on the ground? Quote Link to comment Share on other sites More sharing options...
LR90 Posted January 1, 2006 Share Posted January 1, 2006 Typsey, get the temp problem sorted first as that can badly affect mpg. Quote Link to comment Share on other sites More sharing options...
Typsey Posted January 2, 2006 Author Share Posted January 2, 2006 Typsey, get the temp problem sorted first as that can badly affect mpg. Temp problem now appears sorted. The mpg loss had already started well before the water pump failed. There was a little bit of diesel (i think) apparent of the road yesterday morning after a night of being parked up.

BogMonster Posted January 2, 2006 Share Posted January 2, 2006 Most common source of leakage is the leak-off pipes rather than the actual metal injector pipes - those often need changing on a 300Tdi, and on a 200Tdi the washers on the top of the injectors leak. But I don't know about it affecting MPG by that much Quote Link to comment Share on other sites More sharing options...
Typsey Posted February 14, 2006 Author Share Posted February 14, 2006 Just before I headed up into Scotland, I saw a small drip coming off the gear box, whilst I was down there changing the oil. At first I thought the worst, but the next day when I had some time to investigate, I noticed the smell of diesel. I checked over the whole system, but didn't notice any obvious leaks. Started the engine up, then looked again, and saw small bubbles coming out of the injector leak off pipes. Straight round to Halfrauds (my independent dealer shuts at 2pm on a Sunday) and to my supprise they actually hard some replacement hose which didn't cost the earth! A bit annoying really as I did just have it in for service and they couldn't find the problem! MPG back up to 30+ which is lovely! Happy days.

LR90 Posted February 14, 2006 Share Posted February 14, 2006 So the tumbling penguin gets it right again. Glad you got it sorted though Quote Link to comment Share on other sites More sharing options...
BogMonster Posted February 14, 2006 Share Posted February 14, 2006 I think you'll find a DIY repair won't last too long - it never seems to whenever I have seen somebody do it anyway! - so it might pay to obtain and fit a proper leakoff pipe before it goes again. It's another thing where genuine ones are a lot better than cheapo ones as well - the cheapo ones sometimes have the pipe blow off the unions, where the genuine ones have a proper lip that the pipes push over on each union to hold it securely.

Will check this out ASAP with local dealer. Thanks a lot Quote Link to comment Share on other sites More sharing options...
