I dont know if its just me, but does your Jag feel more heavy in the winter months, i mean a lot of hard thuds on the back end i dont think its like this in the summer months when it hotter.

Any thoughts?

I've had some issues with suspension this winter - my local jag man thinks it might be the anti roll bar which is knocking a little bit - but I doubt season related. They'll have  alook next time I take the car in but not worth worrying about in the meantime... But I'd be interested to see how your car fares once the weather gets warmer and if the issue goes away. 

The (air suspension fault)came up on my dash board,,i changed the pump,suspension is fine but the warning keeps coming on,,,(Air suspension fault)

Any ideas guys
