Hello, drive a Mazda 6 GY diesel with 100 kw, BJ 11/2004 and nearly 108000 km on the clock. Now to my problem, for about a week I hear as soon as the engine is warm a quiet rattling noise out of the engine room. Sometimes it disappears and comes back, in front of everyone in the lower speed range and in the stationary gas at the traffic light it can really annoy. Have it today quite well located and I think it comes from the vicinity of the Lima and the timing belt. Someone an idea or a similar it already had a problem? It was changed 3 weeks ago the starter but I would exclude it as a source of error. Thank you very much in advance for all the answers. MfG Mike
