Audi 5000CD Turbo

Hey guys.  

I'm sorry if the questions I ask have been asked before.  I searched 
the archives but came up empty.  I am obviously new to this list.  
My friend owns a 1986 Audi 5000 Turbo 5 Cylinder 5 speed.  He is 
having all kinds of problems with it now and is not sure where else 
to turn.  The Audi dealers are trying to charge him too much to 
figure out what the problems are so I figured some of you may be 
able to help me.  Here are a few of the problems he has:

1. The car will start OK, but will run horribly rough.  You have to 
drive with one foot on the gas and use your other to brake and 
clutch.  If he drives it for about 1-2 minutes, then if he shuts the car 
off, then restarts it, it idles perfect.  You don't need to hold the gas. 
 I was suspecting possible cooling sensor gone bad?  Or am I 
wrong and if so what is the problem?

2.  If you start the car without the headlights on, all dash lights are 
dead.  If you turn the headlights on first, then start it, they work fine.

3. He can drive the car for hours or minutes as long as it is nice 
and warm.  If he shuts it off, it will always start as long as he 
doesn't wait longer than 10 minutes or so.  Anytime shortly 
afterwards, the car will not start.  It will roll over and over, get fuel, 
but there will be NO spark at all.  If you wait 3-8 hours, depending 
on how cool it is outside, it will start up again.  For example, today, 
he drove it to work (20-40 minute drive), shut it off. Waited 5 
minutes.  It started right up.  Waited 10 minutes and now no spark. 
 4 hours later, still no spark.  But it will start tonight when he leaves 
work like 5-6 hours later.  What could this be???

4.  He had a problem with the cold start fuel injector (can't 
remember exactly what) and someone had rigged it up to a switch 
so he could manually switch on this injector.  What problems can 
this cause?

5.  The front power window swiches won't work.  If you hook up the 
front windows to the rear window switch on the driver's side door 
panel, they work.  Bad switch?

Is there any way to pull fault codes from the vehicle without having 
the dealer do it?  I know some cars flash the check engine light, 
giving out problem codes from the computer.

I know there is more, but I think I have bothered you all too much 
already.  Please either reply back to the digest here or drop me an 
email at golden@qwpage.com

Desperately Yours..
