Open Question

Audi 500SEL fuel efficiency

Goodday!

Is there a way to better the fuel efficiency of my 500SEL?
It currently gives me a overall average of about 8-8,5L/100km.

Any suggestions please?
Kind Regards
Willem

I have a 1993 audi 500sel and the alternator does not work,i want to know if a 1998 audi a4 2.8 v6 alternator will work on my engine which is also a 2.8 v6 motor


same or bigger amperage should be no problem
where a problem may be is in the earlier alternator there may be a voltage regulator either in the alternator or external to the alternator
the later alternator by be regulated by the ECM

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.

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 all.you 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.
