Hello people. just thought I would share this with you. basicly my car has been getting very intermittent power/torque when pushing the throttle, some times my car would feel like a 1.6 petrol and others it would shift like the 2.5tdi should. car is on 158k, full timing belt, tentioners, pullies and aux belt and pullies just changed and car runs smoother and quieter due to all my pullies having play in them but the car still felt gutless at times. so I checked the mounts and found that my snub mount was completely worn. So I changed that and boom all my power issues have gone, engine feels solid and gearstick has next to no movement when pulling away and chaning gear and the biggest bonus I have instant torque when I press the throttle! Not sure how this works but im guessing with the snub mount worn out I was loosing torque due to the engine movement and possibly it electric mounts detecting the movement???? Im not clued up on the electric mounts o the car so I dont know if they are able to tell the ecu to cut the power if the engine has excessive movement. anyway its worth checking if you 2.5 is having power issues. I was almost putting mine down to vains on the turbo being clogged but it wasn't! main engine mounts will be replaced next month for peace of mind!
