I was driving my car home today and it was running really well then all
the sudden i got an anoying beep to look up and see the little oil can
light come on then my car just totally shut off. is this a safety for
low oil or oil pressure i cant seem to get it to restart for anything.

You may have broken the timing belt. $$$$

Hopefully, it is something more easy to correct.

You should pull the ECU codes.

If you are not into mechanical work, have it checked by an independent mechanic
that is familiar with Audis. Check the mechanic's reputation with other local
Audi owners.

Did *all* of your dash warning lights also come on?  If they did it
probably is a broken timing belt.  When you try to start it, does the
starter motor sound high pitched like it is turning without any
resistence?  If this is the case, you definitely have a broken timing
belt.  Low oil pressure (little oil can light) shouldn't have caused
your engine to stop.  It might make some clickedyclack noises soon
after, but not stop the engine.

Is there an easy way to check and see for a broken timing belt? The guy
i got it from recently changed the timing belt not but a little over a
year ago. I cant get it to restart it really sounds like its turning
over with not alot of resistance at all and im gettin no spark to the
spark plugs. i sure hope its not the timing belt.

I dont know if all the lights came on on the dash but it was
almost like someone just shut the key off and the engine instanly shut
down but nothing else in the car shut off or interupted.

Is there an easy way to get the ecu codes without needing a computer
reader and how do i do it if u can read them without a special computer?

There is a method for pulling the codes but you would need a manual to interpret
them.

Based on your feeling that it is turning over with little resistance and no
spark I would guess that you did loose the timing belt. Sorry.

The previous owner may have changed the belt but there are other items involved
in the job like tensioners, idler pulleys, water pumps ... that can also cause
the failure. If they all had not been changed then the job was not done
correctly and I think that you have paid the price.

Flat bed to an Audi shop to verify.

Nice car to have that happen but it sure sounds like that is the problem.

>i sure hope its not the timing belt.

Sorry, Bill, but it sounds like a timing belt.  The engine would not
just suddenly shut off if the oil light came on.  Chances are you ate
some valves.  Tow it to an Audi dealer or have a mech look at it
wherever it is.  It will be an expensive repair and may not be worth
it considering the age of the car.  Good luck.

can u pull the distributor caps off and check to see if they are
turning would that tell u if the timing belt broke or not?

Is there an easily accessible timing belt cover? If so, pull that and look.

I guess.  But believe me, a car's engine does not just suddenly stop
like you describe unless it is a timing belt.  If you try to start it
and the starter is turning without resistance, it is a timing belt.

welll pulled the distributor cap when i got home from school today the
rotor isnt turning. So im pretty sure its just like everyone says its
the timing belt. they want 3000 to put one in it at an audi shop.

That sounds a bit too much.  You will priobably find bent valves which
would require replacement.  If you have it done (I wouldn't) replace
the water pump and thermostat.  I'm wondering how much you paid for
this car and if it is worth this costly repair.  It sounds like you
were the victim of some smooth talking dude who would say anything to
get rid of the car.  I'd go back to him and ask when and by whom was
the belt changed.  You may have a case against him.\

Good luck.

i bought the car on a auction and it had a bunch of reciepts from the
stuff this guy had done to it. he didnt have the timing belt replaced i
looked over the receipt and called the dealer that did the work and it
was a serpentine belt so it hadnt been changed in the past.

I payed 225 dollars for the car on the auction cause the day it sold it
was snowin and cold and no one showed up and there was no reserves.

What would be a average it should cost to have a new one put in it. i
am not sure if i will get it fixed yet or not i might even have my dad
try to help me do it myself instead of a shop. its really a nice car
and ran awsome before this happened and the leather interior is like
new so i hate to junk it but it might still not be worth a fortune to
fix.

Other than your current problem, you got a good deal on it. A V8 Quattro in good
shape often will sell for $1,500 to $3,000. You need to be sure about the T belt
in the V8 because when it fails it is usually considered more expensive to fix
than the car is worth.

Replacing the T belt when it hasn't previously failed should cost $1,200 to
$1,800. When it has failed it almost surely has broken valves and trashed
pistons. The only fix to consider is to replace the engine and that will
probably run $4,000. Fixing the engine would run more than that.

Audis are very nice cars but they are merciless on you when you don't keep up on
scheduled maintenance.
