both my cooper d i bought like that but both had dpf issues ie bought cheap one was total nightmare as past owner did not know what the truth was and how to tell the truth, ie its turbo failed before went in to diesel runaway and hurt the bottom end badly think it cracked the oil feed within block as it cast alloy and have seen another recently do same trick i would guess and only way out of it is another engine complete, good thing is a ford or pug or volvo engine fits straight in with a few wiring change over etc, and reprogram the injectors etc.
after this i always deleted the dpf filter and egr valve on any 1.6hdi and transforms them and should never get turbo melt down again but still need to change turbo at 80-100k ish for piece of mind,

Hi Mike, I'm hoping you can give me some much needed advice as you seem like a knowledgeable chap. Apologies for jumping in this thread.
I've just purchased a 2011 Countryman 1.6 D Cooper D from a local garage. Originally a demo model then one owner with full history and only 32000 on the clock. Happy days or so I thought until my MPG is only 37! I do a mix of mainly local but some motorway day to day and though the spec says 64mpg I thought I'd at least be nearing 50! My last car was an Audi A2 so used to getting alot more MPG.
Also have got warning message that auto stop/start not working so will return to garage to see if they can sort that as still in warranty period.
Any thoughts on why my MPG so low would be greatly appreciated. I've been taking it steady too which is most unlike me!

so you have the n47 diesel thats bmw own engine used in all there range form 1.6 to 2.0 with the timing chain at rear of engine but with those miles you should be ok for a while yet,, trouble with mpg its worked out by makers in a control way, on the flat none windy day on a set distance etc,, so try driving up a motorway with not many hills for 50 miles at no more than 50 mph with cruise control on think you will see 64mpg,, i've had hundreds of cars and i live in a town where to go anywhere it all hills at mo i got 2.2 cdti vauxhall suv around town 40mpg but i dont go above tick over hardly to get that when in down ie 30 mph,, if i drive it where it should be driven to keep the dpf filter happy ie over 2000 revs its 30mpg but on run at 50 mph i can get 50mpg out of it, its 184bhp so never need to rev it anywhere, sometimes a smaller engine is cheaper depending on how driven etc,
have heard a lot of people say the n47 in mini does worst mpg than same engine in the bmw 3 series or 1 series but in those its 2.0 and starts off at 180bhp ish less revs faster you get to speed without reving it best mpg it seems

Thanks for getting back to me. It's an r60 apparently. What does the dpf filter do then? Is there any way of improving MPG with mapping? I've been taking it steady but 37 is rubbish, especially when other folks with the same car say they're getting close to 60 at times.
