Need to replace airflow metering box on my 1994 BMW 316 E36 M40 engine. Part costs £350 new so would like to buy used part. BMW will not give me the part number!! Don't have original part for this and have tried loads of metering boxes that just don't fit. Please help have been tryng to get my motor back on the road for three weeks now!!

Really need more info about your car. Month and year manufactured, sedan/coupe, transmission, catalytic converter or not, and even LHD or RHD all make a difference. But try this, 13621734653 or go to http://www.realoem.com and find it.
