Hi all, new on here, bought my sedici 5 weeks ago, 56 plate 1.9 multi-jet. drove it for 2 weeks and seemed to be having problems starting car up as it doesn't always turn over, also noticed car judders alot when in stationary position..... just wondered is this normal? its very noisy too. It went back to the garage ( under warranty ) for 2 weeks had new starter motor, fuel filter, egr valve replaced injectors and new battery, alternator checked. had it back for 1 week, not started 1st time in the morning all week, sometimes does later in the day. would the cold weather not make it start first time everyday? my last diesel car managed to start in all weather. any ideas anyone?
