hoping im worrying over nothing here, was driving last night came to a halt at a roundabout and just as i was picking off i felt a big rumble through the clutch pedal, i could also feel a rumble on the accelerator pedal afterwards too, it also feels as if i need to use the accelerator more to get her going, as it also feels really sluggish now compared to before when pulling away if that makes sense

its a cdti 120 with 340000 on the clock, and im taking it to the dealer this week to get yet another wiper motor (3rd in 3 yr) the warranty runs out in 3 months so im wanting to make sure everything is sorted before hand so any advice would be welcome
i have just had 2 new tyres fitted and thought it might have been them but i have been doing motorway speeds and everything feels fine
