Any updates on how to fix

Hi I have been chasing this for 3months now without success infact I have given up :-(
there seems to be two school of thoughts, 1. The turbo orange seal. 2. Crankcase sensor part no above but no hint or pic showing its location.??
As said I have given up and letting the wife crack on, will get rid when she starts to get it!!! as she says it never happens to her :-/

The crankshaft speed sensor is down by the oil pump. See here:

RealOEM.com BMW R55 Cooper d Lubrication system/Oil pump

Available here on Ebay. Not expensive

Hi, I've also been chasing this on a 2009 Clubman D (full service history, I am the sole owner) for about 1 year. Recently I've developed a new-found obsession with solving this problem.

I've changed oil, oil filter, air filter and have thrown in a can of diesel injector cleaner. This helped the car run smoother but has not solved the hesitation/loss of power issue.

Last weekend I cleaned the MAF sensor and checked all the connections for the intake piping. I discovered the orange turbo seal at the inlet is split and have ordered a new one. It's scheduled to arrive at the end of the week.

Cleaning the MAF helped somewhat, but the car is still not what it should be. I'll post the results of replacing the turbo inlet seal.

From reading and browsing Peugeot and Citroen forums, I've discovered that other possible causes could be the EGR valve, turbo vacuum control solenoid and the air doser (a.k.a. throttle body butterfly valve). However, the dealership doesn't want to start charging me for new parts for nothing as they are not pulling any error codes from the car.


I'll post updates when I have them.

Scotland Newbie with BMW engine Cooper D

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).

[QUOTE
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.

So frustrating.

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?

my hesitation got a bit better after a 40 min constant drive up the motorway.

but the flat spot is still there as is the poor MPG it is only 36 around town and 44 on the motorway driving like miss daisy

where is the orange seal?

i have ordered:

new airfilter
forte diesel treatment
forte dpf treament

Orange seal sits right at the turbo intake. Follow the piping from the airbox to the turbo, where the pipe joins the turbo, you'll see the seal. My new one just arrived today, haven't changed it out yet, but would be willing to post pictures if anyone is interested...

Just to add my advice here, you can see from my posts above I'm chasing the same issue. The air filter change and diesel treatment did nothing for me. Cleaning the MAF helped, but marginally only. I'll update on what happens after I install the new rubber seal.

FYI, I'm getting 4.7L/100km which works out to about 60UK miles per gallon on a 2009 Clubman D. I've been between 5.2L/100km and 4.5L/100km since I bought the car. I find tires make a big difference.

Can't help you there, I have no experience with a dpf delete. I know from reading the Peugeot/Citroen forums, some people have had varying degrees of success by blocking of the EGR valve with a steel or aluminum plate. However, it seems that post 2007 engines tend to throw a CEL in many cases...

Drove the car this morning with the new seal. Seems a little better, but I'm still missing some power in 3rd gear. Higher gears remain relatively unaffected it seems. Could be because I'm feeling the Overboost function which operates from gears 4-6 and increases torque by about 20Nm. Definitely I'm missing some acceleration power at the low end in 1-3. However, the car runs really smooth and there are still no error codes.

I'm wondering now if I haven't got some carbon buildup in the breather intake which could be restricting engine airflow or something. Could also be something stupid like a small hole or crack in the intercooler piping.

The more things I eliminate, the more I think it's simply due to the high mileage on the car rather than a problem with an engine part.

Please let us know how you get on. I'm really curious to put this problem behind me. Been chasing it for over a year now.
