Peugeot or BMW 1.6 - Which is better?

I skipped through some of the other thread re: the newer 1.6 Diesel engine used in the Mini.

2007 - 2009 is the Peugeot PSA 1.6 engine
2010 - 2013 is the newer BMW 1.6 engine
2014 onwards is the brand new 1.5

I have been hunting down a Dooper. Basically hovering around a 2009 or 2010 model with the right spec. So this made me wonder, is there any reason to get the BMW engine over the Peugeot one? Or is the older engine better?

Or just too nuanced for it to play any part of the buying decision?

Thanks

I've got the 2009 PSA engine in a Clubman. I'm at 130,000k with nothing but oil and filter changes. I get the stated 4.7L/100km fuel efficiency. I'm happy with the engine in this car. Still on the original battery too.

Some people have complained about the fuel comsumption figures on the BMW engine, but I have no long-term practical experience with that although I have driven both engines.

In terms of refinement, the BMW engine is much queter and smoother during the Stop/Start function. The PSA engine is a rather loud beast and not so gentle during the Stop/Start process.

If you are a DIY sort, then the PSA engine takes up less space in the engine bay and is easier to work on as a result. Should you need it there is lots of help on the Peugeot & Ford forums as the PSA is used in a wide variety of car makes.

Hope that helps.

It does, thank you. Constant source of knowledge

Do you know if the 2010 1.6 BMW engine needs the turbo seal replacing, EGR cleaning, like in the Peugeot one?

I've only read positive things about the one you have to be honest, and noise doesn't bother me. The things like the turbo are simple. I was just curious as much as anything really.

I did read in that thread about the BMW not getting the same sort of MPG figures as quoted. Whereas all the 2007-2009 ones I've looked at are doing 60-70 through casual use. Not that it makes a huge difference, but the earlier Peugeot engine seems more consistent in that regard.

Turbo on the BMW engine is mounted down behind and not easy to access, unlike the PSA which is front-mounted. Never heard of anyone having to change the seals on the BMW engine or do the EGR - at least not on the forums. For the record, I'm at 130,000 with the PSA engine and have never cleaned the EGR...

I had a relatively serious and expensive issue with the clutch about 18 months after I bought the car, so it hasn't been completely trouble-free.

As regards the fuel consumption, mine was using more than quoted until I hit about 55,000km then it settled down to the quoted figures. When I bought it in 2009 it was giving me 5.1 or 5.2 L/100km.

Interesting, thanks again!

Was your clutch issue predictable in any way, or just straight up unlucky?

I haven't read/heard of any known clutch issues, so I'm guessing you were just unlucky, sorry to hear that. Could I ask what it was? Was it thousands to sort out ?

I'd actually been hoping to get one with 35-45K on the clock, so if I do I guess it'll still need time to bed in.

At idle, the clutch was making a knocking noise when I first bought the car. I complained about it under warranty. Eventually the clutch started slipping. Mini covered the flywheel as a goodwill and offered some discounts on labour, but I still paid a tidy sum to have everything put in order. Came out to about €1400 total (after discounts). The story is all documented on this website - think the thread was "Clubman Clutch Despair" or something like that.

Since that episode, the car had performed beautifully, so I think it was just bad luck - likely a bad flywheel.

Dont Don't get the PSA, unless you can guarantee it has been well looked after, the stats are great and they will give the recorded mpg,but...turbo problems 1500...Dpf 800 etc...all well known issues, look at Peugeot/ford/Manda forums for the horror stories.
My local garage reckons they are now replacing at least 1-2 turbos a month on these engines..as a pointer the local motor factors holds the turbo (a 600 item) on their shelves.
Great when they work,but expensive when things go kaput.

I've ran Peugeot diesels for many years XUD's and Hdi's and the PSA is basically an Hdi and never once had a problem with any of them. My current R55 has the PSA engine and this was the reason for me buying it. Keep the engine serviced regular i.e regular oil/ filter changes and it will look after you!

My wife had a 307 (2008) with a engine 1.6-liter HDi DV6 I4 the same which is in 07-09 Cooper D . With regular service on the engine turbine gave up after 45000 Km and authorized mechanic explained (who is a good friend of us) that the turbine gave up because it was left without lubrication and that was a cause. She now has MC 2.0 SD (2013) with BMW engine N47N for now without any problems 20000 Km to see.

I've got a 2007 Mini Cooper D with the Peugeot engine & found it really reliable so far...I'm getting 55mpg driving around town in traffic & was surprised by how quick it is for a diesel but you can definately tell its a diesel engine when its idling

Turbo failure is common if the oil level hasn't been checked and topped up on a regular basis. When the engine gets low on oil it then starts to starve the turbo. I've recently added another R55 to the fleet and the turbo is worn on that but I got it at a good price as it has 127k on the clock. I'm going to be rebuilding the turbo in the next few weeks and just gathering up all the bits and pieces just now
