No luck changed the o2 sensor today and the coils .....waste of time codes cleared then came straight back again.....this looks like the dreaded carbon buildup or a sticking valve grrrrrrr.......gonna try the seafoam treatment first......if that doesn't work looks like the heads gonna have to come off...........

Do a compression or if you can a leakdown test to se if that shows any problems

thx for the reply man aye i'm gonna do a compression test tommoro.....seafoam was a waste of time tried it today.....and i also found out the carbon issue only applies to the S anyway so another 20 wasted.......you cant win with these problems either you go to a dealer and get fleeced often with the problem still not diagnosed correctly or you do it yourself and waste money changing stuff hoping for the best....ahhhhh the joys of motoring....crazy thing is the car runs like a wee gem above 1000rpm loads of power and smooth as silk....just can't understand what could be the issue surely a damaged head or valve would be apparent at high revs also.........from what i've read online so far these N12 pug engines are chocolate teapots....with a whole host of issues even with low mileage examples ...simply not fit for purpose.....a shame for BMW......just hoping its not gonna be a lemon...our cooper D with way more mileage runs like a dream

Wondering could this be a faulty MAP sensor ? would explain the poor/lumpy idle does the MAP sensor throw up any codes if its bad ?

UPDATE

checked the plugs today all look nice and clean a nice tan colour with no pitting
i removed the lambda sensors both.... and cleaned them
i topped up the engine oil as level was lowish
i sealed the flange between the cold air intake and the airfilter housing which was loose

i also ran a can of Cataclean through it incase the seafoam had clogged up the cat

i cleared the codes and touch wood she seems fine gona take her for a thrashing now hope this has sorted the issue....seems all to easy tho....nothins ever that handy....

to date

NEW BERU OE PLUGS
NEW COILS
REPLACED BOTH 02 SENSORS
SEAMFOAM TREATMENT
CATACLEAN TREATMENT
INJECTOR CLEANER DIRECT TO THE INLET MANIFOLD/FUEL ADDITIVE
CHECKED FOR VACCUME LEAKS
CHECKED INJECTOR WIRING
CHECKED OIL LEVEL
CHECKED VAVLE COVER FOR CRACKS/LEAKS
RESET ECU

COMPRESSION TESTED

CYL 1-173
CYL 2-174
CYL 3-172
CYL 4-173

I'm fresh outa ideas man

maybe crank/cam sensor but surely that would thro up a separate code directly related to the component that is failing ?

I'm in way over my head now looks like a replacement engine is the way forward by the time i replace everything releated to this misfire i'll have spent near the same money....madness

Another update folks i'm getting closer now.......changed both camshaft position sensors today and the car instantly began running better although still off a cylinder,this cant be right i thought so to my horror one of the new coils i installed weeks ago was breaking down every now and then,i put another coil in to check and the car instantly came to life......moral of the story don't assume new parts are faultless.......now the car idles fine and the misfire is gone as is the check light.....well not quite when i pull up to traffic lights sometimes the revs struggle to stay at idle moving between 500rpm and 950 rpm with the check light flashing then going out.....similar to the original issue i had although not as severe,this has gotta be a software issue with the ecu/dme i cannot think of any hardware problem that would cause this also there are no stored or pending codes being picked up either thank goodness.....it has improved like 90% over the previous state however i'd still like to have it running 100%.........thx for all the replys folk any others with similar problems post away if you think it may help

are there any other engine control unit faults other than the cylinder misfire faults?
I've seen r56 thermostat cause a lot of problems when they go bad.
Trying bringing up a live coolant temp reading and then find the coolant temp sensor in the thermostat on the left side/back of the motor. top of the thermostat it's a green plug. pull on the wiring loom lightly see if the temp reading bounces around a lot
