A4 Cabriolet 3.0L Quattro.
My wife was driving, EPS light went off, stalled, restarted then stalled again.
Towed home 2 hrs later, started for 30 seconds then stalled and hasn't run sense. Initial VAG scan was AIT sensor. 4 calss to the dealer to learn it is supposed to be a combo unit in the MFA. So i cleaned the MFA and still won't start.
IF I SPRAY STARTING FLUID DOWN THE AIR INTAKE IT WILL RUN AS LONG AS I KEEP SPRAYING.
So I change the combo fuel filter/pressure regulator, while disconnected I turned the ignition on and pumped a couple of cups of fuel out of the tank, so I THINK THE FUEL PUMP IS GOOD. But I can't pressure check it. Now I get a "steering angle sensor G85 lost signal terminal 30" code.

Anyone figure out how to diagnose all these sensor issues?
Any help would be greatly appreciated.

Does anyone know what codes will put the ECU into no start mode?
Thanks
Rich

Thanks for the advice. I got fed up and replaced the MAF, that was easy. But it didn't solve the problem, still won't start.
Any other suggestions?

When the esp on, it threw a code, I had to reset it and everything should be back to normal. Make sure none of the vacuum hoses are broken or unplugged at the intake. All sensor plugs are connected
