MAF Sensor

Hi All,

i was wondering if anyone could assist. My 2008 pre lci 320d has an intermittent problem.

1)On the odd startup my car takes alot longer than usual to build up boost
2) the turbo whistle is much louder and the engine sounds alot deeper when accelerating albeit much slower acceleration due to lack of boost.

when i park the car and leave it for a while/overnight and start it up again. it would be back to perfect running order????

could this be because my MAF is on its last legs?

Thanks in advance,
Jono
