Recently my hands are getting numb from driving my 520d. Can even get headache. There is a high frequency vibration coming from the engine even at idle. At the last service, made a complaint to the SA at TS Ipoh. But after service was told all normal. So I suffered in silence. Then today went to TS to check on their 520d for similar vibrations as it is becoming unbearable. Definately not the same high frequency but a low frequency and very mild vibration only. Not the type that will make your hands numb or give you headache. After pointing out the difference to the Sales chap(Service Adviser on training course), contacted the SA by phone and was told to come back next week for a good check. Hopefully no more numb hands and headache from driving my 520d soon.
