My A6 is having some issues.

Symptoms:
-Just turns over, backfires occasionally
-Tries to start, finally does and dies almost immediately.
-Throttle does not keep car running.
-Has gas, tested ignition, getting spark, has compression.
-Tried to read codes, getting message "Unable to make connection" or something like that.
-Only once, I received message saying "Press clutch to start engine" -It's an automatic.

LOST!!!

Did the car die on you or was it working fine the last time you drove it? then the next time you went to start it was like this?

Throwing any codes? Could be fail coil packs... How long have you been on the current Timing belt?

thekingofvtec

im not sure about codes. it wont even read them. telling me unable to connect to computer.

and awhile, i bought the car used with this belt on it, so idk. its starts and runs, so i doubt it timing.

Have you tried cranking the motor for 6 seconds and trying to read the codes? Have you tried a different scanner yet?

ive tried more the one scanner, same thing. its the car. replaced all of the breather hoses and the temp sensor yesterday, at least it starts up right away now, but still stalls right away.

I had a problem like this and my intake air hose was disconnected from the airbox. I reconnected it and it ran perfectly.

I had it towed to Audi the other day, they had it for 3 days and determined the main problems are the ignition coil and the alternator. I replaced the coil when I got home and still same thing, cant imagine a bad alternator keeping it from running when being hooked up to another car. Its getting gas, at least to the fuel rail, not sure about the injectors, spark is fine.

Is the air intake hose the hose in the front of the box?

So... had it towed to my guy the other day, he is not sure whats wrong with it, but he told me that I first needed to replace the alternator and the coil pack.

Replaced alternator and coil pack, put it all back together, tried to start it...

Now i get...

Crank, crank, crank, starts, runs for maybe 2 secs (a lot smoother and quieter), I hear a loud audible beep, then it dies. Its almost like the beep is telling me something is wrong, but i really have no clue.

So guy hooked it up to his diag, still gets no connection, so he thinks the computer is bad.. is this a possibility?
