406oc.co.uk

Been under the bonnet over an hour, taken all air filter housing apart and cannot find air flow sensor.
Has it got one? Should it have one?
Even my bro has checked it out, he fitted his own on his Golf, and he cannot find it. Says it should be there.
Any help please?
Its a 1997 R plate 1.9TD

dont believe there is one mechanical fuel pump. maf sensor only needed to link to the ECU.

doesnt have one
the 1.9 in a 406 only has a partial engine management, and has no need to see measured airflow
