Freelander under powered, has had problems starting now it feels like I'm towing

Hi there I'm new here and this question may have been answered B4 but I can't find anything on it, I bought this land rover Freelander L series about a year ago and since then I have spent thousands keeping her on the road.
I now have a problem which I can't figure out when driving it feels like the car is holding back and when I hit a hill there is no power at all I was thinking a possable turbo failure! Is there any way of check the turbo and how easy r they to replace/repair
Thanks (wishing I had bought a disco or defender instead of lisening to the wife)

had a similiar problem when i hit hills. a new ignition coil sorted it for me. there are 2 in freelanders. and 1 of mine had failed.

Have you tried checking on the brakes or on the propshaft bearings. BTW mine has the same symptons but mine hsn't got a propshaft.
