Sorry Mr Stuart please forgive my naivety I've only had my Freelander three weeks and until now have never been under the bonnet of any vehicle other than to top up the windscreen fluid. This is all a major learning curve for me.
The crank case filter has not been replaced as yet, I have just received the service parts today that I ordered last week, Mann oil filter, Mann Fuel filter, Air filter and would like to order if its a sensible thing to do the upgraded oil separator/crank case filter and have not yet purchased engine oil as I'm not sure which I should use.
As for the MAP sensor, I have no idea what that is or where its located. I also do not know what the Turbo actuator is.
I got the car three weeks ago, and went from London to Devon for the bank holiday weekend with it, it was only on the hills and when I kicked down that I noticed the lack of power and black smoke. had never driven one before that so didn't know how it should perform.. so I guess it had been like that since I got it..
please , no need to ever apologise , will get there in the end
will find some pics for u to tell u where parts are, sorry i meant maf not map , doh,
the replacement of the crank case breather is very important , get the upgraded BMW type, it's a very clever designed piece of plastic that doesn't need changing
shame ur not closer otherwise i could have helped u fit the parts etc, am in swanley kent and gone through the engine
if we start with the easy bits first to eliminate as a matter of course , can then tick them off as we go along ,
