I have driven V8's for the last 30 years but after losing my beloved 1988 V8 110 in a fire, I have purchased a 2003 TD5. Having sorted out the damper which was causing the horrible noise mentioned in my previous post, I can start to get to grips with, what appears, to be a different driving experience. Once warm, and the turbo kicks in, she pulls like a train and her speed in the gears seems fine. Better than my V8. However, she does seem to need a few revs i.e. she does not pull at tickover. Also, when she is cold, she will baulk at any steep hill, often stalling. If I keep in a low gear, often first, and rev higher than I think I ought, to she is ok. When warm she is fine.
I am not sure whether there is some adjustment needed or it is me, not being used to a diesel. Any thoughts?
 
Could be a whole host of things, mostly electronic. Do you have a diagnostic?
Meanwhile it might be worth disconnecting the MAF and seeing if it runs better, taking out and at least cleaning, with sensor cleaner, the AAP sensor and the MAP/IAT sensor too. If this doesn't improve things then you need a diagnostic, minimum a Foxwell, for live data.
You could also check how many threads are showing on the wastegate actuator rod, 13 should be showing.
But yes they do run better when hot usually although on start-up it shouldn't be as bad as that.
If you are used to the simple huge grunt of a V8 then yes it will drive differently.
Best of luck with it. When running right they are great to drive.
 
Thanks for your comments. I have had a look and found that there are only 9 threads showing on the actuator. I will wind it out a little tomorrow and see how I go. I will also try disconnecting the MAF and let you know how I get on. I do not have a diagnostic.
 
Before I go and play with the actuator tomorrow what effect will I be looking for i.e. If I wind it out i.e. show more threads should the turbo come in quicker or later? and what effect would winding it in have? Should there be a delay on the turbo? If so, how much etc? Sorry for the questions but being new to a diesel and to a TD5 I am not sure how it should behave.

The turbo actuator is wound in on yours to give more power, so maybe a previous owner also had a problem.
See this
Running without your MAF connected will send the ECU into an inbuilt map the same as one from an earlier D2.
There is always an amount of lag with these turbos. But not as abd as on the 300tdis.
 
Ok As An easy first step, I disconnected the MAF. It ran, but not great, worse than before. I reconnected it and it worked like a dream. Much quieter, the pickup was smoother and I was able to tackle some steep hills at tickover, or just above. Flooring it in 4th on a windy road quickly built up to 120km/h, 75mph, with more in the tank, before I chickened out. I never got around to the Wastegate actuator and think I will leave it at that whilst I order some sensor cleaner. Not sure, if disconnecting it and reconnecting reset it or just helped the connections, but it seemed to work.

Glad to hear it.
You can of course clean the maf carefully, i.e not touching it, with sensor cleaner but it does sound as if it wasn't properly connected.
 
Thanks for your help! Very welcome as not a lot of land rovers around here although a neighbour is very good with V8s and has a 101. Landrover savvy garages are non existent. I am happy playing with a V8 having had one for 30 years and my wife has still got one, although we did sell our 101 a few years ago. Diesels however are still a mystery to me at the moment :)

2003, they need MAF, horrible without one
