Hi my B Max is Diesel 1.6 Titanium.
Driving between 30-40 mph there is a vibration under the car floor and from under the bonnet.It's like the car is labouring!
Been back twice Dealer say there's nothing wrong and I think it's geting louder,
Any clues anyone,

Mine is not a diesel but I had a similar problem in the early days.

It went undiagnosed until they put a mic underneath and drove the car whilst listening to the sound.

It was found to be related to the exhaust heat shield which I presume is between the engine and the passenger compartment, hence the sound seems to come from both areas.

I think they either tigtened it or moved it slightly but whatever they did effected a cure,

The fault was not picked up by visual examination so maybe worth asking them to do a similar test.

Makem, good idea. Thanks for this I am going to take it to a different dealer.
