hi all
i am new to this!!
i have an 02 reg freelander 1.8i station wagon 35000 miles, she runs as if she is being held back, very flat. i have had her serviced by tune-up/ hometune and they reported to me that the emmissions were very high and that we had an error code on the diagnostics which read "0170 fuel adaptations out of range" from this he concluded that the lambda sensor on the exhaust manifold had packed up and needed replacing. this i did and no improvement has been seen:(
can anyone shed any light on the error code or what would be making my freelander drive so sluggish (i took a 51 reg 1.8i out the other day and it flew in comparison)
i have searched the web for the error code and have found nothing
oil and water are both fine with no loss of either or mixing!!
any help would be greatly appreciated
regards and heres hoping

I have job going with a local farmers wife's 1.8 k series - similar problem,inactive oxygen sensor,poor performance etc.After lots of checks with Testbook and the trusty Oscilliscope I went and borrowed another MEMS engine ECU,perfect - problem is sourcing another one/having it repaired.Not saying this is what is wrong with yours but its not the first time I've seen it.
 
You should see her sat on a bar stool with a fag in one hand and a glass of whisky in the other - QUALITY !! And they say us country folk dont know how to live.:D
 
i did not think ecus could be swapped between cars i thought they were programmed with all that cars info etc etc?
does this mean it is worth going to the stealers to have it reprogrammed, how much would that cost??
any ideas
 
Mems Ecu's on 1.8 FL's just need a security reprogramme via Testbook,you really need to get a decent LR independant specialist to check out your car,where are you - do you know any good ones near you ?
 
fuelling adaption faults could mean other things, you could have an air leak somewhere, if thats the case, no oxy sensor will be able to cope with the extra unmetered air going in.

in cases like these especially with the k series (all lr petrols in fact), after a fault has been fixed, the ecu adaptions need to be reset as it will have "learned" the fuelling stratagy with the fault present.

A good example was when i had a 1.8 freelander in for a service and i noticed the vacuum pipe was off from the inlet manifold to the ecu, the engine was running fine but when i connected it back up, it ran like a bag of **** because the ecu has learned the fuelling stratagy with the pipe off, I reset the adaptions and it was fine.

could be the same case as your oxy sensor, try resetting the adaptions.

It will, over time reset itself as it learns the new stratagy once a fault has been fixed.
