Freelander @ Limp home mode/engin problems

[Twister110]

My dad who is in his senior years has just treated himself to a new to him but secondhand Freelander SD4 2010 with 72000mls on the clock.

It was fine for about a week and then he mentioned to me that it had throttle lag intermittently. I said it would be a bit of turbo lag but when driving it I found out that it was much more pronounced than that and is definitely a problem.

The following day his car went in to reduced power limp home mode so he took it to his local garage. After plugging it into there diagnostics machine it said there was an exhaust problem and the guy said to drive it on a motorway keeping the engine revving to clear the diesel particulate filter which he did and it worked and the problem seemed fixed.

Still all this time the throttle problem was ongoing and then the car went into limp home mode again and the engine waning light came on and that is how the car stands now. I drove it tonight and the engine was lumpy on startup and a later start up needed a second turn to get the engine going.

He's booked the car in at the local garage again next week but I said he may be better off going straight to Land Rover who know the car and might know the problem, what do you think? Other wise what are peoples experiences at Land Rover specialists and can anyone recommend one in South Bucks.

Any advice is much apprecated and thanks for looking

Welcome.

Forum etiquette is to pop into the introduce yourself section and tell us a little about yourself.

Then come back and some kind soul might take pity on you.

If it was a Freelsnder 1 I would have said replace the low pressure fuel pump and fuel filter, but it isn't so I can't help.

What code/s came up on the diagnostic machine ?

There is some info from the German LR-Forum and in the Freelander's section with more than 100 pages written it is the longest thread.

The system is so complicated and goes deep into motor management that a lot of things (pressure sensors, AGR-valve, every small leak in the exhaust gas system etc) can contribute to a DPF-full-message, which very often followed by engine going into limp mode..
JL
R knows well about the DPF-related problems and dealers here are exhausted to satisfy repair requests.
There is no notification from the car when the regeneration process is under way and if uncompleted for several times in row, DPF-full message pops up.
The system checks not only the clogging-grade of the DPF, but also counts the cold engine starts and mileage. After every 850 km and a certain number of cold starts a regeneration is initiated regardless of the cleanness of the filter.
Especially manual-gear box owners and city / short distance drivers seem to be affected badly. The frequent DPF regenerations lead to dilution of engine oil and in the worst case have been said it can ruin the engine... but that may be a rumour !

Make sure that the software has been up-dated, they have issued Q212-Update as a fix for car going into limp-mode right after first 'DPF-Full'-message, I'm not sure if there have been any others

More informed people will be along shortly ...

Thanks for that.

Unfortunately he didn't purchase it of a dealer so it he doesn't have any come back but has brought a non Land Rover warranty so always has that to fall back on.

With regard to the diagnostics message I will check with dad on the error code but I doubt he will know that, but did say it came up with DPF problem. The diagnostics was done just a local garage so I never know if they can get as much out of the car diagnostics as a full Land Rover garage.

That "DPF full" message does that come up on the dashboard as he hasn't mentioned that.

Latest software is defiantly one as I saw that mentioned somewhere else so thanks for that also reading up throttle body failure people have mentioned on there cars.

Thanks again
