Customer Question

My 2006 Kyron mercedes engine 1958 XDI Semi Auto. it has started to make a high valocity sound when engine is warmed up.this sound which comes on during normal driving just before it changes to a higher gear and this lasts a few seconds then it returnes to what i feel as normal again. it does not sound as though something is broken or worn but it is worrying. i have twice had it to a dealership who have first charged me to say that nothing was wrong. the second time i went with the mechanic who heard the noise but still was not sure the of the cause, he later decided to change the drive belt at my expence which made no difference. still leaving the problem mentioned unidentified. this sound can be induced while stationary by increasing the engine revs slowly or quickly. can you please advise me what possiply can be the cause and is it a serious problem. i have no oil leaks or loss of oil to the best of my knowledge.
