BMW 730 head gasket failure
I have a BMW 730 petrol manual. A few weeks ago the engine warning light came on, relating to the MAF sensor. The car seemed to drive fine, so I ignored it.
Just under a 1000 miles later the car struggled to start and I'm now told the head gasket has gone, which is a result of me not rectifying the original sensor fault. Is this correct?

Ah, I think what they are trying to tell you is that the mass airflow sensor fault led to the engine running unduly lean, which would raise the temperature in the combustion chambers and could have led to the head gasket failure. That's the logic, anyway.
