Hi, I'm new on here could anyone helps with my td4. I sold my 98 plate freelander (diesel) to buy a newer one and got a 2003 td4 but everytime I get near 70mph I suddenly lose power as if the turbo stops working. I'e read it could be the solenoid vac so I've replaced that. Still same I've just fitted a new fuel filter and pump on as it failed on me the other day but still have no idea. Can anyone help?
