Hi xperience,
No. Dealers (I've been back to 2 now) haven't really come back with too much positive on mpg. However I've now done about 4500 miles and it does seem to be slowly improving. Long term average about 45 and motorway journeys at 70/80 getting close to 50. One thing I have noticed is these things take a lot longer to warm up than the old PD motor I had. I have a 10 mile country journey to work. My old Audi A3 used to do 47. XP does between 38 and 45 now and very dependant on outside temp. Today its 12 degrees outside and I got 38. One day last week it was much warmer and got 45.
Being anal I tried exact same run when motor warm. I got 51.
Both dealers have said that there's a lot more metal on these Haldex 4wd that needs to bed in and that makes some sense to me. I've also been recommended to not use supermarket fuel. I only switched last week and that does seem to make the engine run smoother.
I did read somewhere that somebody else with a 184 FR had lousy mpg which suddenly improved after 5000 miles. Hope springs eternal
I've found ECO makes no difference to mpg at all. In fact working the engine helps to warm it up quicker and mpg doesn't suffer that much.
My elusive knock bothers me more. Like a ping pong ball in a can and much more pronounced until the cars done 20 or 30 miles. Happens when accelerating especially when pulling out to overtake and when going uphill. Seems to be coming from under right hand side of car but maybe transmitted sound from the engine. No luck with tracing it yet but I'm gonna keep persevering with the dealers.
