By the way guys, is there a way of cleaning the turbo while on the car assembled, with a Aerosol Turbo cleaner which prayed through the intake? Or is that not a good idea and there no point in doing so?
to everyone who owns a diesel mini i will try and explain the chain of events that will happened not if its when,
so you buy a mini with say 60k on the clock got full service history been loved and just had additive tank refill and reset counter, and off you go thinking that all is good now,, hmmm trouble is these engines are by design due to the dpf filter and what it does a very dirty engine that stores the carbon that would of gone out the exhaust if it did not have a dpf,, so this carbon now is everywhere including the engine oil. same engine oil that cools and lubricates the high pressure turbo bearing and oil seals, so at around 80k the dpf is at the end of its life and needs replacing or as some try cleaning,, but a lot of people at this point get told to go and race the hell out of your car to generate heat to aid regeneration,, where really you should go and replace dpf filter with replacement and re do additive tank and reset the system ie the ecu needs to be told it has now got a new filter etc, by racing the engine with a massive back pressure that also the ecu on regen adds fuel and changing timing to increase heat to regen then cooks and over loads the turbo,,, this is where it gets stupid, so turbo will fail and the engine oil gets sprayed straight in to the air intake,, a diesel engines loves this as it burns oil so goes in to over run, this is where you can not stop engine from reving at 10,000 revs and will not stop until its used all the engine oil,, this then starves the engine of oil destroys it every bearing face run dry,, so at point of car needing a dpf at 60k would cost £200 for filter and £50 for additve and £50 for reset,, you end up with refurb turbo £200. dpf and cat £400 at new engine £2500 or secondhand one at £700 plus the labour.
or car dont go in to over run you and been lucky, so off you go and buy a new turbo bolt it on replace the oil pipes and clean out sump do injectors seals but dont change the dpf filter and reset it.. so car runs ok for a few hundred maybe thousands of miles but soon it will once again destroy another turbo,, and the turbo company no matter how you have fitted a new turbo will invent some reason for not replacing your new turbo as a faulty item.
prevention is always the best way to service any thing, except that some things have a shelf life and must be replaced.. garages tend only to deal with stuff when it breaks because they make more money then, main dealers will always say no there is not issues with any of their products even when the internet is rife with expensive problems all the same,
