Lack Of Power - TD4 Adventurer

Hello All,

Not taken long but only had my 06 plate Freelander for a month and i have noticed a problem.

At first i did not think the acceleration and power was as good as my old 02 plate TD4 but i put this down to the fact it had less than 15000 miles on the clock.

Now when i pull away from a standstill it seems to hesiate and then all of a suddent the power appears. I have also noticed that when driving the power will dip for a second or so then come back on.

Spoke to Stratstone today and it is booked in next monday for a Software Update as they hope this will just cure it.

Will keep you informed of what happens. Apart from that the car is brilliant and much improvement has been made on the 02 plate one i had

Before going to the garage, try to disconnect the MAF to see whether you will get a different result when driving away. Could be a MAF failure.

I would have expected an engine management light on if it was the MAF? Mind you, an easy one to try so does no harm...

Have personally never driven the car with the MAF disconnected so can't tell about the engine mgmt light, but have seen several others who did and none of them mentioned that light came up ??

Have driven the car for several weeks if not months with a faulty maf and no engine mgmt light came up during that period. If that is what you mean ?

I might well be wrong about the light on LRs. I know from experience of buggering around with MAF relate stuff on other make diesel cars that any MAF problem (or disconnection) tends to make the engine mgmt light come on.

Feel free to ignore me...

Funny that you should mention it - I've also just bought an '06 Td4 Adventurer on 14.5K miles, and mine is exactly the same. If you haven't got quite enough revs on when pulling away it's very prone to stalling.
I thought it was a characteristic of the engine (having come from a 225BHP Leon Cupra R), so will be interested to hear if you get this sorted. Otherwise the motor's great - just needs a few choice accessories now...

UPDATE...... Got the Adventurer back today and they told me the turbo modulator was at fault and they replaced under warranty. Car now seems to pull a lot better so fingers crossed

Funny that you should mention it - I've also just bought an '06 Td4 sport (3 06 td4 with the same problem)

the MAF's will only generate a trouble code if they totally fail, usually they just drift soooo far out of spec they affect the engine, but dont cause errors.

UPDATE....

A couple of weeks ago my 06 Freelander started to again develop the same symptons when driving and also was taking and age to start on a cold morning.

After another visit to my friendly Land Rover dealer, Stratstone in Durham, who, by the way, I could not recommend highly enough, especially Dave in the service department, diagnoised that the 4th injector was not working correctly.

Fixed under warranty and my car now feels totally different, it now seems to have a bit of umppph.

Thanks Stratstone

dave,, i had a similar problem ie lacking power and poor tickover, injector cleaner sorted it out,
i use cleaner on a regular basis now, and the engine seems very lively now, seems like these injectors really need to be kept clean for best performance

thats what i thought, i am gonna start using cleaner every couple of months or so
