My tdi 115 has started making funny sounds recently. When i pull off in 1st gear i get a rumble sound from somewhere in the engine bay, its only in the low down revs, it sometimes occurs when ive changed gear and im accelerating through the next gear. sounds like somethings loose but ive had allok round the engine bay and nothing appears to be loose/hanging off. Hope it isnt the gearbox/diff. Any common issues which follow these symptons?
Thanks
