Having my Insignia 2.0 CDTi 130 SRi some 5mths now, although very pleased with car.

But found the engine is not much good with braking on overrun in 6th, 5th or 4th having to use the brakes more than my previous Citroen Gr Picasso 1.6Hdi in same conditions on motorway etc having to allow greater space although not a bad thing but allows more idiots to jump into gap between me and one in front.

Are all these like this or need to visit dealer.

thanks
