my friend has a renault clio and she says she has noticed that the engine sounds louder that normal. She had it serviced a few weeks ago and has checked oil and water. She has just moved to another county and does not know anyone who will check it out . What could the problem be ? would it be worth the 150 km drive back to her usual garage. She is a student so has little cash to go to a main dealer. She is now in the galway city area. any advice welcome
