Old Audi won't start properly

I have an M reg Audi A4 which has a problem starting and then just dying. I start it again and give it some throttle and rev it for a half a minute and it keeps going and drives ok until the next time I need to start it. It is getting worse each time now and needs more starts before I can keep it from stalling.

It could be a number of things.
First check all air intake /vacuum system for leaks
Then check the fuel lines/filter.
If all okay the you will need to check the following.
MAF (mass air flow) sensor
CKP (crankshaft position ) sensor
CMP (camshaft position ) sensor
IAT (Intake air Temp) sensor
ECT (engine coolant temp) sensor
EVAP (Evaporative emission cannister purge valve)
