Hello dear MotorTalk community, would need your advice Have been having problems with my SL350 R230 BJ 08.08 62tkm, MOPF 2 For about a week now, when I’m giving up I’m getting a “bumping/summing sound” like a compressor running high. In the lower speed range 1,000 to 2,000 rpm until the automatic is switched up. For example, if I drive on the highway at 100, the noise is as good as gone. When braking, the whole thing is more likely to be in some kind of trouble when switching down As if the speed would go down at each turn off short too strong. Now I was at the friendly and I was told appointment would only be in 2 weeks. In the stand to give nothing to hear about the gas, for short ride no time… Sad though the only 3 months ago made large service for just 2k…. If among other things automatic oil was probably changed, probably at 60tkm should stand uniquely. spark plugs, air filter, fuel filter etc. I am now not so knowledgeable what autotechn I hope you can help me, or give me a tip on what it might be. Thanks already in advance ! Thorsten
