Hello all,
I've just purchased a 2010 HSE TDV6 3.0 which drives very well and is an all round wonderful car except for some vibrations in that drive me nuts.
There are 2 separate "frequencies" and types:
1. One is more or less only noticable in the sterring wheels when it is in an off-centre position and power is given. This intermittant steering wheel vibration feels like an electric toothbrush when it occurs. The problem can be demonstarted when the car is parked, steering turned about 30degrees and one depresses and releases the gas pedal. It rises and drops with engine RPM.
2. The second, more annoying vibration can be felt through steering pedals and seats. It is most obvious when the car is in "D" stopped at a tradfic light. The vibration is of a lower frequency and higher amplitude that the in part 1. The vibration is related to motor speed and can be reduced by about 70% by putting the car into "N" when stopped. It is not dramatic, but it is not what I would expect in a luxury vehicle - even a diesel. I've tested it with an Iphone vibration measurement app and it seems to be a 35-37Hz vibration at idle (in "P") with a .005mm amplitude on the steering wheel (should that be of any help to anyone).
The car idles at about 800rpm and as far as I can feel the vibration seems to be gone at about 1100rpm when in "N"
I would be very grateful to hear if anyone else had either of these vibrations. Are they normal in the TDV6 as my dealer says? any solutions or ideas to improve the situation?
Many thanks in advance,
Bob
PS I hope that this is the correct forum for the RRS?
