Hi was wondering if anyone could suggest why my 2005 td5 defender with 33000 miles and full service history has started to loose power when I try and accelerate from 35ish up. When this happens I am lucky if I can get 25mph. I did notice a high pitched whirring noise coming from the engine compartment a few days ago when I switched off. it had a new fuel pump fitted about 6 months ago. any suggestions wouold be greatly received by this landy virgin
