I have a 06 td4 freelander 1 it’s developed an intermittent noise only when the car is under load. The car will judder and make the noise then drives completely normally this only seems to happen if your trying pull away fast or gain speed. The cars not got the best of power but after a new maf sensor does seem to be better but not great. I’ve attached a link of the noise it’s really bizarre and googles a minefield.
