Hello to everyone, I have the following problem with my Volvo V70 D5, 120 Kw, 180TKm, stop gear M56, Bj,2003, in cold condition one hears klappern from the transmission area. In warm condition the noises are gone. Car drives quite normal, while driving one hears nothing, even no vibrations or similar. If one taps fast on the accelerator pedal in cold condition and only slightly increases threshold, then the noises come. I have to say that I have changed the transmission oil (Castrol Syntrans Multivehicle 75W-90). It seems to me that the sounds have occurred after oil changes have occurred! I also changed the engine oil at the same time (Castrol EDGE 0W40). Before that I had 5W30 Castrol EDGE in it. Something is wrong, either it is related to the oil or to any bearings!???? What do you think, has someone had the same experience? Ask for your help!! Thank you in advance
