A4 idle speed
I have a question regarding the normal idle speed for an un modified 2003 A4.
I can't find any specs in my FSM.
It is my son's car. It idles at 600RPM in neutral & 500 RPM in gear.
There are no performance/driveability issues. He feels this is too low.
Just for comparison my unmodified 2002 manual idles at just under 800 RPMs.
Thanks, Bill

He posed this question about a year and a half ago and I couldn't find any info.
I replaced his hazard switch for him a couple of days ago and after several hrs. of coaxing a very discharged Optima red top back to life I was able to start the car and check out all the systems. I was surprised that the car idled so low.
When revving in neutral and coming back to idle sometimes I could see and feel a speed droop below 600RPM and the engine felt like it was going to stall but always recovered. I didn't check it in drive.
Any way it seems to be happy where it's at.
Thanks for the reply, Bill
