Audio 500sel starting problems when it's hot or after filling petrol

When it does this hard start buy and keep a can of spray starting fluid in the car, spray it into the engine air intake, if it fires right up you have a failing fuel pump.

My 1993 AUDI 500SEL 2.8 V6 is swinging but won't start, . A mechanic said that the module was broken I replaced but is still no difference, apparently there is no spark on the spark plugs an injectors

depends on the module he was referring to
it could be the ignition control module but it could be either /or both the cam /crank position sensors , the immobilizer module or ECM unit
BUT would be best to have the fault codes read first and then fix the problem/s that are found

I have an audi 500sel 93 manual AAH Engine, no fire to the plugs, car refuses to start. checked computer box, 2 crank sensors, modulator, the coils all tested okay and fuel coming to injectors ok. timing...

We will star a list of what is good.and what controls spark
1. crank sensor .you done it
2.ignition control module. located on the center of bulkhead,behind intake air hose
3.coils. you tested it.
4.ECM located under passenger side foot well

ECM no you got fuel,so lets leave it out
cranksensor okay you replaced it
ICM ignition control moduel.
no spark you cover everthing. has to be a loose or no contact connection somewhere, you covered it might want to tap on the ecm., or check the fuse for power to junction the ones in the hood area those can blow and not give power to ignition system

Petrol ron95 or ron97 is better for sport car? Why?

Most modern cars can use either, the computer systems adjust running parameters to suit.
If you are after maximum performance capabilities of the engine and maximum fuel efficiency, use the higher rating.
