Cheers Dave, I will have a look!
The tyres are hankooks all round, and they are less than a year old, I've done about 8,000 miles at a guess on them so far.
I spent most of the weekend under the car, I have up and down movement when holding the wheel at 12:00 and 06:00 on the drivers rear wheel. I'm not sure if the play is from the wheel bearing itself (I had this replaced last year) or the upper suspension are bushing.
I've also got a corrosion spot/ hole on the rear axle on the drivers side.
I've now noticed when I'm changing from eco to comfort mode there is a short rattle sound coming from ether the back of the engine or the gear box, it sounds like some sort of electronic switch or solenoid, I'm unsure if this is a tore restrictor for eco mode which is on the gear box?
This made me wonder if the original vibration is coming from the dual mass fly wheel under load, which in turn tells me why it doesn't do it in eco mode as its restricting the torque?
I hope this isn't the case!
This leads me to the question, what actually goes on when you put the car into eco mode? I'm intrigued to know what actually turns on and changes, is there a torque reducer that is turned on? along with the throttle that is made more spongey.
I'm interested to know what happens when this is activated as it may help me understand a potential other problem that could be starting!
