Asked by Matthew Jan 23, 2012 at 12:23 AM about the 2007 MINI Cooper S

Question type: Maintenance & Repair

Had the MINI almost 2 months and the oil light comes on, when checked the oil is low. After filling it back to the proper level runs
fine but a couple weeks later same issue comes up again. I heard this is because of the turbo but sounds unlikely. Any solutions
to stop or slow the oil burn down?

turbo does burn some oil. Check for obvious oil leaks. Also check around the crank seal. If oil is leaking from there it will burn off before dripping to the ground

No obvious leaks so far, but will definitely check around the crank seal for any leaks. Will that produce any other symptoms that might give it away?

Prince engines (those used in 2nd-gen MINIs) have a technical service bulletin out for a leaky turbo oil line. If your MINI is still within warranty, go to the dealer and complain of oil loss, and bring the TSB sheet in. They'll repair it, gratis.

When I bought the MINI it was out of warranty. It seems to keep doing this, I have to take it in to fix the aux water pump and will ask the techs about that.

ANY EXTERNAL OIL LEAK WILL MAKE A GREASY MESS EVENTUALLY ... cHECK the pcv hose and pcv valve .. as this creates an internal vacuum to the crank case thereby greatly reducing the likely hood of leaky seals or gaskets . SOOO we look to Mister turbo 's compressor side oil seal , This seal will operate under manifold vacuum until there is boost pressure present . and a leaky compressor seal will evenly divide consumed oil between all cylinders... so it may not ever smoke or knock period

These cars are nothing but junk... Poor assembled,poor crappie service,nobody can give a straight answer about the ton of problems they are loaded with...and at day's end, we have to check oil every thousand miles, if I were riding a horse I wouldn't be doing that, I had all these problems, from oil to chains to trunk not opening, to brake pads that have to be changed before I blink, to rattling sounds from dash board, roof and no one at the effin dealers have a clue... Never again...never

Mini Cooper of Long Beach said..."BMW says that loosing a liter of oil every 750 miles, is normal" Because of high" amount of pressure under valve cover, pushes oil down intake"..........Meaning they have no idea why.
