Slow to accelerate from stationary
Since this exceptionally cold weather has been with us, I have noticed that my Disco 3 Diesel will not draw away from stationary as normal. It moves off very slowly, and does not respond to the throttle in the normal way. For those of us old enough to remember, it feels exactly like a cold petrol engine with manual choke that has not been pulled out far enough. As the engine warms up the problem dissapears. It make driving out of junctions a bit tricky to say the least.
Any ideas?Ian L

leofwen, it is exactly that, winter mix diesel glazing in the injectors......or battery soon to go pete tonk... or even the alternator showing early signs of going south
Quite a few threads on ere in recent weeks regards batteries and the symptoms, me personally had that problem when the cold weather first started, took it to stealer the very same day the throttle became very unresponsive, found no fault other than recording the battery taking a large hit when starting - new one fitted, all fine for another 3/4 weeks then alternator packed up (although not starting never was a problems since the battery was changed)
so to narrow down your issue, does yer FBH work, how old is yer battery and is it a OEM LR 950 amps?

Thanks BP that article is great and does clear up a lot for me. Just to take on a small point mentioned in the article about whether a fault comes from the valves being stuck open or closed, surely the problems must be caused by the valves sticking open at the wromg time, or otherwise blanking them off would never cure a problem.
I am now off to check the function of mine. Do yo know what effect fitting plugs has on performance and economy and emissions?Ian L

there seems to be conflicting stories about performance and economy after fitting the blanking kit, so I guess it will be a suck it and see. As per my topic, my nearest independant would not entertain talking to me about fitting the blank kit! so i have founf another, TERRAIN VEHICLES just down the road from me who are going to do a diagnosis check on mine MOnday . They recommended fitting the blank kit as fitting new valves is only s hort term fix!
The valves fail in the open position allowing un clean gases into a cold engine with no rpm to digest etc. Mine improves greatly if the air is warmer and the engine is up to temp etc.

I would be very interested in seeing what your diagnostic checks reveal, if you are willing to publish.
Do you have any references to the purpose/function of the EGR system. The only thing that makes sense to me is maybe to attempt to reburn some exhaust gases and therefore give cleaner emmisions, so logically fitting blanking plugs should make the emmisions dirtier at moderate engine revs. Maybe we can get away with it in the UK because our emmisions testing is not as rigorous (or is that ridiculous) as in the USA. Possibly the existance of the EGR system is yet another example for us all paying the price for decisions made in the USA.
Once again many thanks for the response and the help.Ian L

Hi leofwen,
You can't blame the USA for the egrs as the TDV6 was not imported into USA.
Instead, they are a function of EU regs.

After testing as suggested by bornpompey, I found the offside valve was blowing gases, and the neasr side was OK , so I bought the blanking set from Bell Auto Services (great service, ordered on line MOnday night delivered Wednesday morning). It's now fitted in about an hour and the difference is amazing. It's like new again.
A by product was the amount of gunge in the ducting. I manged quite easily to remove the duct so I cleaned it out. See the picture below.
I'll post details of what has happened to the economy in a few weeks.
