Hello, i bought a new Scenic 1.9 dCi in August 2004. I tried both the 1.5 dCi and the 1.6 petrol, they were OK but the 1.9 has good power/torque and good MPG. I hear that the 1.5 dCi has better MPG but i prefer more power/torque over MPG. I get between 35 (town) and 55 (longer journeys) and feel that is good given the size/weight and aerodynamics (brick!) shape.
If you surf the Web you will find horror stories about the
on 1.9 dCi`s, when they were first sold the service interval was 18000/2 years !! I have always changed the
on my Scenic every 6000/6 months using a Renault filter (not expensive) and fully synthetic 5W40 good quality
, and not had any problems.
As far as home servicing goes most is OK to do at home, just a bit filddly due to lack of room under the bonnet, nothing a bit of time cannot fix !!
One important thing to look out for is the Cambelt change, its due at 72000/5 years whichever comes sooner. I had mine done at a Dealer, also advisable getting the aux. belt and tensioner, and waterpump done at the same time ! Could be a bargaining tool if it has not been done, i paid just under £500.00 for mine. It sounds a lot but, it could be a big bill if it goes Bang !
Hope this helps, regards Damian.
