2008 Freelander 2 2.2 TD4
Been having a problem recently with the engine losing power.
Symptoms:-
If cruising at ¾ throttle the car is fine until I put my foot to the floor on inclines or to overtake the car dies until I take my foot off of the accelerator then it will pick up again I can feather the throttle to keep the boost on but If I demand full throttle the car dies.
The Turbo boost shows 22.5 psi on full chat and then dies to around 5 psi until I go back to ¾ throttle.
I have used Torque android app to read the ECU No fault codes are showing.

If I drive the car hard through the gears the car will accelerate all the way up to and beyond the speed limit with no hesitations and will keep going until I run out of road.

I have changed the fuel filter, checked the turbo waste gate which operates freely by hand.

Any suggestions would be appreciated as I'm at a loss don't you just love modern cars!

What happens to rpm? Another member of the failed FL2 clutch/DMF club, twice.

Hi many thanks for reply
The revs just stay the same no increase or decrease

At least the flywheel is ok  Another member of the failed FL2 clutch/DMF club, twice.

Sorry to drag up and old thread but I have this issue.
Did you ever solve it?
Thanks

I also have a similar issue.. but my freelander 2 just misfires/looses fire for a split second when accelerating then recovers. FL2 GS

On mine that was due to a clogged fuel filter - no codes just symptoms No Longer the owner of a 2013MY Fuji White GS

"Fiat Lux" a philosophy not a car

Ah okay, mine had a replacement fuel filter 6 months ago before the problems started. FL2 GS

Ive changed:
Throttle body
Manifold presuure sensor
Air temp sensor
Fuel filter
Accelorator pedal
Had turbo actuator tested no faults
Made sure actuator arm and veins move freely and lubed.
Problem still exists

Im thinking could be:
In tank fuel pump
Fuel rail pressure sensor
Stop light switch (apparently the ecm monitors this)

If I unplug the maf will the car still run using a pre-set values?

My old mk1 freelander would.

Cheers

All that 'round' has done is pretty much the logical route to go with the absence of fault codes.

From reading your post - you haven't changed your MAF sensor and I have known of these being faulty and not throwing a code. I would also suggest you get live data to rule out the fuel rail sensor but I'm no expert there so can't tell you what readings you should actually be seeing?? 09 FL2 GS TD4e Current

My mechanic specialists in LR and his neighbours FL2 had the same problem and it was the Fuel rail they replaced, no problems since but they also had to replace everything like you before finding it.

I put some injector cleaner in mine 9 days ago, it hasn't misfired since but doesn't mean it won't.. i'm waiting for it. FL2 GS

I soaked maf in brake cleaner and flushed out the intercooler which produced alot of crap.
Problem still exists
Will try new maf and egr next
Cheers

Have you trie changing the crank sensor.

Ok so I blanked off egr no change.
I cleaned maf no change
I unplugged maf and fault goes away but I have noticed that without the maf plugged in it stops the egr from working too so I suspect it’s still either the maf or egr or maf wiring.
I will look at getting egr mapped out to elimate that and then try a new maf.
