Can anyone help, about two weeks ago my car started to make a 'rumbling' noise whenever i went over 2000 revs, it would then stop for a while then it would come back..not sure what it is. could it be the turbo or a split in a pipe somewhere any help would be great..

could be anything with such little info it may be aircon bearing a tensioner failing a wheel bearing to name a few certainly worth investigating you dont want a tensioner bearing fail you

thanks ..its more like whining noise...but only happens when ive been driving for a while...the rev counter hits 2000 revs then the noise kicks in....but then it doesnt happen all the time..

Without hearing a noise its difficult to say theres so many things from turbo bearings to wheel bearings ide certainly have it checked if youre not sure

after listening to this noise carefully now, its sounds like a dump valve. esp in 1st the revs hit around 2000 and there's a loud 'psssssst' noise.

i changed the air intake pipe as the little pipe leading of that was cracked, but now i don't where else to look. it doesn't affect the performance of the car as its still quite nippy..i have a 07 1.6 tdci...any suggestions would be great ..and yes you may have to draw pictures..thanks

after checking all the pipes etc..i found that a lot of jubilee clips were loose..so after tightening them all up the noise has gone...
