its a known fact you'll get coking on the N14 engine but if you're lucky enough to land an N18 engine then you should be ok. Engines drinking large quantities of oil is the first sign although BMW say that they allow 1ltr of oil to be used per 800-1000 miles which i think is total tosh. If you're not happy get it looked at.

Better to go off the build date rather than registration date to be accurate.

N14 engines also suffer with timing chain tensioner issues which should be done under warranty. Make sure you check the service history that its been done. N18 engines don't suffer from this from what I am aware of. Both N18 and N14 engines sound like sewing machines but if they are exceptionally loud especially from cold then it needs doing.

Apart from that they're pretty solid. Not sure if anyone else has had any issues though

Hi. Thanks for that guys. I will be sure to check the build date of the mini. Would the dealer know which engine it has?

knowing dealers..... probably not but you'll be able to tell from the build sheet which they can bring up on their system using the VIN

The N18 didn't replace the N14 in JCW models until July 2012 builds.

Find out the last 7 of VIN and use the BMW VIN Decoder to find out build date, engine type and equipment for the car.

N18 JCW - Stop/start. JCW badge on engine rocker cover.

To name but a few

Most of the issues you wont discover until you own the car for a few weeks or months... My 08 N14 dealer fit JCW, I appreciate wasn't a FJCW had so many issues but it took me a month to work out all the issues and that I bought from a dealer. The previous MCS 2007 N14 one had similar issues with regards to engine.

I now own a FJCW N18 engine which I have has for a week and waiting to see if there are any issues.

Common faults that I have had in most of my cars are the key holder being fiddly and having to be replaced on both, radio cuts out when the rear deimister is on element corroded and having to replace entire glass on both, the rear wiper jets blocked and replaced, AC needing toping up.

I am on my third R56 and all have had issues which were all replaced and sorted under warranty, on your 12 plate you should be ok... are you getting it from a dealer or private sale.
