New to working on these cars. What are the functions of the power module? Do they measure airflow? I know the turbo intake hose goes through the module.

pm supplies and switches power for different things in the car like ignation , fuel pump etc

it switches power on to things through the asd - automatic shutdown relay

it also contains your voltage regulater for the chargeing system

there are a couple common things that affect it

if the pick up or wireing for the pick up in the distribuator is bad - the asd will not send power from the module to the ign or fuel pump

if the voltage reg goes bad you don't need to replace the module - just disconect the field wires going to the pm from the alternator and add in an old style voltage reg that bolts to the firewall or inner fender
usually a much cheeper fix than replaceing the module
