How does the A3 sports suspension compare to the regular one? Is it
harsh, with too much road noise, as opposed to the one that comes with
premium package? Any input would be appreciated.

Yeah--so I was driving home from SF to LA on the 5 freeway at 4 AM.  All
of a sudden, the gas pedal stops working on my 2004 A4.  I press the
gas, but there's no acceleration.  I pull to the side of the road and
stop the car.  The car won't start.  But there's strong odor of gas

I need to find the Altitude sensor on my 1988 Audi 90 2.5 NG engine.
Are there any repairs maintence for the Air Flow meter? TIA
