Hi everyone, I'm new to this forum and any help would be very appreciated, I recently bought my landrover freelander td4 hse 2005 model, really like the car however had some issues regarding loosing power around 70 mph and then a black smoke appears when I put my foot back down?? No lights on dash what so ever, been advised it's turbo boost pressure sensor do I have purchased one at £36 plus vat was told is quite easy to find and fix but in having trouble finding it, could anyone please a advise. Thanks
