Freelander 2 (LR2) Temperature Related Power Loss Woes

If the auto gearbox wont pull away and accelerate in Drive, but will do in manual mode, then the physical gearbox itself is working ok if its shifting up manually as you request it. The only difference is your making the decision when to change gear yerself as opposed to the car making the choice.

If the accelerator pedal sensor is at fault intermittently then you would expect the car to sense this. There will be a reading on the diagnostic of its position. Measured as a voltage or % of travel or both. Both usually. A garage could monitor this while taking it for a drive.

When the fault happens pump the accellerator pedal to see if the engine revs respond. Do it in Drive and Neutral. If the revs don't increase when in Neutral then this rules out the gearbox by process of elimination.

There is always shared parts across a range of vehicles. It keeps the cost down. It would be daft not to.
 
Sorry lads had the notifications off and didn't see replies to this thread

Just got the car sorted last week after a lot of hassle with the Main Dealer. In the end, a Main Dealer clean and forced Regen of the DPF resolved the issue entirely!

Thanks for letting us know the fix.
 
Full diagnostics done at main dealer no codes, throttle body changed as they said that was the problem. Driving great now so hopefully that's the end of the problem.

Update on my issues with lack of acceleration from standing start.
Had the car in to garage and software updates done four weeks ago. Lasted two weeks.
Back in and showed a error code that lead to a throttle sensor.
Replaced sensor it's a one piece unit and comes with complete pedal unit
Lasted another two weeks.
Back to garage yesterday and the garages top technician looked into it. Turns out that it is the aftermarket fuel filter fitted by an independent garage who did an oil and filter service on it...will update again once car back and run for a while.
But it would seem that of all the parts that you can buy as after market replacements the fuel filter is not one to go with the shape and interior are not up to the job and can cause surge in the fuel supply which tells the system to shut down as it's over fueling the system..
Happens especially when sat on ideal as the pressure has time to build .

Are you saying the fuel filter is limiting flow so for eggsample the car won't rev to say 3000 revs or is it broken in some other way? There's a maker on the lr genuine fuel filters to show direction of flow. I have a new one and can put up pic's for comparison.

From what I understand if your sitting at tickover in traffic then put your foot down the fuel surges through the filter to quickly this triggers the safety circuit as the cars electronics think that the accelerator is stuck open and is cutting the system so it doesn't keep supplying fuel ...

Ps it has been working fine since the filter was replaced not missed a beat...

That's good to hear.

If you have the old filter it would be interesting to cut it open to see if the filter is partially blocked or collapsed inside.

I have the old filter but i can't cut it open yet until I have been to the garage that supposedly fitted a authentic Landrover part when they serviced it .
Conversation about some recompense to take place with them so don't want to cut it up yet...but will do if I still have it afterwards
But for those who do go to garages make sure the parts a genuine it's a big problem to deal with for such a simple part.....
Was also pretty ****ed off as I've used the garage for thirty years and never had bother with anything before.....
Have you heard of this issue with anyone else in the Landy community ??

Whever getting stuff 'serviced', make sure to paint dabs of nail varnish on things like filters and other bolts, screws or retainers, and ask for the old items ... this means you can be sure they at least took the old ones off... the replacements should be of 'merchantable quality' ... at least what it says you paid for on the receipt ...
 
Cheers, like I say used the garage for thirty years...
Could be down to luck as the head Landrover tech know straight away what it was when I was speaking to him by my discription of what was happening.
He asked if it had been serviced recently and when I said yes he asked if it was a genuine LR filter used. Which it should have been as soon as he removed the plastic engine cover and looked at the top of the fuel filter he said nope it's not and he even went and got one from the Soares dept and showed me how it should be shaped and where the markings are for both LR and the actual maker that produces them for LR.
Couldn't believe such a simple thing could have such a troubling effect.
He had dealt with a fair few who have had exactly the same issue and always sorted by putting a genuine LR part in...

Might have a new stores manager, cutting corners rather than upping prices ?
 
Its a problem we occasionally come across. Peeps sell a genuine lr part but don't sell what you understand it to be. They think they're getting a genuine lr part which they would get from a lr main dealer. What they're really getting is a genuine part for their lr, not necessarily the genuine part which lr main dealers sell. Genuine as its the right part number to supply.

Yer get different versions. Aftermarket means its someones copy and suitable but may be a different design or performance. In the aftermarket manufacturers opinion it is a credable alternative. That's not necessarily the same manufacturers who make the lr stuff. You often find things are different. Fittings, shape etc. Its a way of making the part sound more credible by referring to the original as if its the same and an optional alternative. Its just that. An optional alternative to the original.

Some part supplies come direct from the same manufacturer which lr also uses for their genuine lr main dealer parts. Cheaper than the main dealer network and the same thing. It won't always have the same 2 year warranty.

The phrase peeps often get caught out with is genuine alternative. As if it's a genuine part as in lr main dealer supply. It is considered to be an alternative for the purposes of advertising, but not necessarily identical. It is genuinely an alternative, but that's it. Lr don't sell or promote is as genuine as it's not. Adding in the word genuine like this makes you think it's genuine like what lr main dealers sell. It won't be.

It most certainly wasn't a genuine part....no LR markings on it what so ever
And looking at the part compared to the main dealer LR stamped bit the shape was different and the tech said that as far as he know the fuel filters were only made by one company ...
IE there wasn't a few making the same part which I believe is a common thing....
The part as far as the LR tech was concerned was a poor copy. And I have no reason to doubt him as he was spot on about the problem stopping with the fitting of the new filter.
As they say you pays your money and you takes your chance.
This Land Rover ownership thing does bite you though
Cheers for all the input...
