hi all
i am new to driving freelanders...so this may be a silly question...i just feel that my new 05 freelander td4 is not running as it should..i have no problem with power once the turbo is spinning....MY PROBLEM is below 2000rpm.....i just feel the car should have more power than it has....the engine feel slow to rev...sluggish...i go to pull out and there is just hardly no power until the turbo cuts in at 2000rpm.....maybe its just me and this how td4's run...??..my question is to anyone else now driving a td4.....can you tell me when the turbo is coming on yours???? .....on mine i have no power then as soon as the revs hit 2000 rpm the power is there... i have changed maf sensor .... i have cleaned egr valve and i have changed the crank case filter.....all pretty clean anyway... i have took the car up to 100mph with no problem.....thanks :doh:

1750rpm roughly. Your problem is most likely your MAF sensor, very common problem. To test just unplug & the ECU will revert to default settings. If the car now runs much better then you will need a MAF. Do a search on here as this is much talked about.

As previously implied old chap it would help the diagnosis greatly if you would kindly disconnect the said sensor and report whether your mount runs better without it.

Yep, that's my point too. I'm wondering if the "replacement" one assuming it's a genuine Lucas as stated has the electrical characteristics of the original Bosch or possibly a Pierburg. As Chaser says disconnection will reveal all.

Hey guys I have the same problem and have swapped out the air sensor with four others and no go. The fault code also shows MAF as being the problem but this does not solve it.
