Hi to all
Im new to this forum and to Land Rover, having recently purchased a 53-reg Freelander TD4 from a friend.
Im entirely happy with it except for one problem, so here goes (sorry for the length of this ! )
At low speed/revs (say between 1200 and 1800 revs) and when trying to maintain a fixed speed of say 30mph, the vehicle feels like its not sure whether it should be accelerating or decelerating, and surges gently every half second or so, as if Im gently pressing the throttle then releasing it.
If I accelerate hard, it does so very well and with no surging. If I take my foot off the throttle to slow down, it does so without surging. I only get the surging feeling when trying to maintain a steady speed. And i should mention that when the weather is VERY cold, the fault doesn't show itself for the first minute or two after starting the engine and driving off.
At speeds over 45mph it doesnt do it, or at least I cant feel it.
Fuel economy is fine, and performance is otherwise ok apart from the car being a bit hesitant when pulling away.
I visited my local Land Rover dealer to have it sorted out, and what a waste of time:
Such was their confidence that I agreed for them to change the hoses and fuel pressure regulator and collected the car the following morning, paying them approx £300.
The Land Rover technician had apparently tested the vehicle after fitting the parts and declared it fixed, but it was obvious to me within minutes that it was exactly the same as when I had left it with them. I returned later that day and spoke to the service guy, who apologised but explained that without being able to retrieve the fault codes from the ECU they were unable to do any more unless I was willing to fund their experiments with various replacement sensors. No refund was forthcoming and I left, feeling rather badly treated to say the least.
I have since done some reading on this forum and elsewhere and I have taken it upon myself to change the MAF (as suggested by Land Rover) but this too has proved to be wasted money.
So Im at a loss where to go from here. Does anyone have any suggestions as to why the ECU refuses to give out its fault codes, or what might be causing the problem? Any help or comments would be much appreciated!
Thank you and regards
Chirky

I visited my local Land Rover dealer to have it sorted out, and what a waste of time:
- They drove the vehicle and could feel the problem themselves.
- They hooked it up to their computer but failed to communicate with the ECU, could not explain why this was, and thus could not be sure what was causing the problem.
- They suggested that the symptoms pointed to a faulty fuel pressure regulator and also identified that some turbo hoses had gone soft and needed replacing.
- They also proposed that the MAF could give the same symptoms.
Such was their confidence that I agreed for them to change the hoses and fuel pressure regulator and collected the car the following morning, paying them approx £300.
