All, So as title suggests, my car has warned me of “low oil” after 2k miles since service. It had also needed a couple of top ups in between services. I’ve added a litre and it’s back to Max. Hoping for the best, I’ve just replaced the crankcase breather on the cam cover, purchased from MKY performance (https://mkyperformance.co.uk/products/bmw-n57-pcv-diaphragm-valve-cover-repair-kit-cap-11127800309?_pos=1&_psq=BMW+N57+PCV+Diaphragm+Valve+Cover+Repair+Kit+Cap+11127800309+330d+430d+530d+325d+640d+×+1&_psid=d7acb3413&_ss=e&_v=1.0) Real OEM doesn’t show the valve as being separate from the cover. No real need for explanation, it’s straightforward enough to do as can be seen from pics. There’s even a 10% discount code on the business card. I removed the compressor inlet duct for access & used a pair of pick tools to unpick the old cover. Old diaphragm was quite a bit more supple and the spring seemed weaker too. Time will tell if it’s cured the oil consumption. 🤞🏻
