ok..so recently ive noticed my car is making a low pitched drone noise..im assuming its coming from the engine (its hard to tell where its coming from when your in the car)..
the noise usually starts at around 40mph..and is very noticeable at 70-80mph..
im calling it a drone..but there isnt any kind of vibration..and when the windows are open you cant hear it on the outside..
its recently been serviced..but the noise didnt appear instantly afterwards..so im not sure what it could be?!?
i thought i'd ask here before i took it to an independant..
p.s my car has done around 100k miles if that helps (it had the cambelt changed about 30k miles ago)
thanks in advance
