maf sensor rrc bmw 1994

Sorry to bore you guys with yet another dull question, but does anyone know where I can find the maf sensor on my rrc 94 bmw 2.5 dti?
All help greatly appreciated. thanks

on right hand side as you look at it pipe going into airfiltter you see plug what makes you think mas senser is f....d?

Thanks J the range, The car is in pensioner mode and wont go up hills. She is booked in the allisport next month to have a bigger intercooler and air filter, they will also fit a chip. After reading some threads on here i thought it cant do any harm to clean the maf sensor, if I can find it!!
