Hi I'm a newbie to posting on here but have been reading posts for a while now and wanted to add my mini experiences
Now on my third diesel mini, first had the Toyota 1.4 engine in the One (56 plate), then moved on to the Cooper D (59 plate) and now proud owner of a 4 day old 62 plate . All my minis have been brand new but the latest model with the BMW engine is like night and day compared with the other two.
Had major problems with the 59 plate (Peugeot engine) from day one but in the past 2 months it was at the dealership for 7 days and the fault still couldn't be found?
When the engine got hot, the start/stop facility made the car cut out really violently instead of just cutting the engine. No fault code was showing but I was told that the problem was the particulate filter in the exhaust not regenerating. Worked okay for a day or so then it got worse and worse. By this stage the car was out of warranty so dealership weren't that interested in finding the problem. Got so bad that it was like driving an old tractor -32k miles on the clock
To cut a long story short, I decided to bite the bullet and traded it in for the new 1.6d with the BMW engine. Best decision I've ever made
Engine so light and quiet and handling so much better. To any of you thinking of changing, it's a no brainer, best mini I've ever had (hope I'm still saying that after 30k miles).
Car's done over 20K miles now and have changed from supermarket fuel to Shell and now to BP diesel which initially seemed to have solved my issues however.....
I was driving along a local country main road last week behind a lorry at a constant 30 to 40 mph with very small throttle openings, at about 1500rpm, when all the old problems reappeared
The dealer has offered to have another look at it, over an extended period but I will probably leave it until the 25k service.
I don't hold out much hope of solving it as it's such an intermittent problem.
In my opinion the fuel 'quality' does make some difference to the overall smoothness of the engine but does not solve my issues with hestitation, flat spots and misfiring.
Perhaps I'll just chop its in against a new one with the BMW diesel engine.
Anyone got experience of the 2 versions? i.e. Peugeot vs BMW diesel engines?
