Is there a dmf on my insignia auto?
Does a 2009 insignia cdti automatic have a dual
mass flywheel? I noticed my car was shuddering on
the motorway between 65 and 70. I could feel it
through the seats. It would come and go rather than
Your auto Insignia won't have a DMF. Problem could be related to engine mounts or gearbox mounts, or there was a service information from Vauxhall about a vibration at 70-90mph that could be caused by rear rubber bushings on the lower front control arms. I take it that you have had the wheels balanced and that all the tyres and wheels themselves are in good order?
Thanks for the info. The car has just had 4 brand new tyres on it so I would assume that balancing was done but may be worth me going back to them to have it checked?
If the problem has only happened since the tyres were fitted I would think that one of them is very slightly out. I'd get them check just to eliminate it as a cause of the vibration. Hope this gets it sorted.
Will do. Unfortunately I didn't own the car prior to the tyres, I had the new tyres put on as a condition of purchase due to advisories on the last MOT. Thanks again
