Maf Sensor Dilemma - 55 Focus, 1.6Tdci Auto
Posted 05 November 2012 - 05:55 PM
Bit of extra info: there is a film of oil on the air box which is blowing out of the engine breather which the mechanic reckons is not due to a leak, just a higher rate fo loss than he would expect from a car with his mileage - it doesn't need topping up between services or smoke much normally as far as I can see, so that may stand a second opinion. He reckons this may be the cause of the MAF getting dirty but not much can be done, and no prob if it just needs an annual clean. Thing is, it's becoming monthly!
So, I could buy a new sensor and see what happens - may not be linked to the oil? I could have another look for a leak - is there a 'classic' spot for this? Or I need a way of diverting the oil away from the MAF. Do you really need one in fact - maybe I can just disconnect it?
Any help much appreciated. I will report back on any results!
