I need some help to identify the noise, which just appeared in the car. My 3.0d went for 30K service (basically only the oil change) few days ago and after that I noticed a very strange noise. It occurs only when car is cold and disapears when warm. It is like ticking coming from underneath the car. Cannot pinpoint it as yet without crawling under but it seems to come rather from the front. It varies in frequency from about 60 ticks per minute to twice as much. It does not depend on engine speed and disapearrs when I switch the engine off therfore eliminating suspicion that it is expanding exhust system. I'm facing very long drive (2000km) just before Christmas and somehow it bothers me. Hope it is nothing serious. The idea of going to the dealer again and explaining the noise, which will disapear by the time I get there, does not appeal to me. Have you got any ideas?
