Air Suction Sound
This is my first thread so please help me!!
Ive got an 147 JTD 16v Multi Jet and love the car, unfortunately i keep getting little niggling probelms and have had a new one pop up tonight. When driving, i heard a sound coming from the left hand side which made a loud hiss sound. Then each time i went above 3000 revs the hissing sound comes back which sounds like a loud sucking sound. basically like air is being sucked out or sucked in, i cannot quite tell and in all honesty am useless when it comes to understanding cars.
Does anyone have any idea of what this can be as im reluctant to drive it over to an ***** specialist which is 20 miles away until im confident im not going to cause it any further problems????
