Hi, My friends S320cdi has recently developed a noise /vibration driving in top gear that starts at about 55mph thru to 60 when driven on light throttle,then dissapears and is normal after that, also if accelerated hard then it drives perfect, it only happens when driven on light throttle, almost seems as though its labouring and should change gear sooner, have cleaned the maf sensor, any ideas much appreciated, are you out there Colin? cheers Dave
