Right , so Ive searche through a lot fo threds and got a few, very vaired opinions about a few niggles with my car... Its a 2003, 318 compact ti se, 2.0. 75k Now and then, when the radio is off, i can hear a noise from behind where the glove box is, (when im driving) which sounds like water swishing around? From what I can find, it seems to be most likely air in the cooling system...so im going to bleed this tomorrow and hopefully that will solve it. Anyone go any other suggestion? Also, ive been buring oil, like a lot of cars seem to, or at least the oi light is coming on around every 500 miles or so (and ive been topping up with 1 litre of oil). I think the cause of this is a worn CCV? housing/valve which will be getting sorted when i find a garage willing to replace it...Other than that the car runs fine, no smoke, no visible leaks or noise...
