[BiturboS4] RE: more hesitation... after a cold start..

[Bill Coleman]

It's a long shot, but you could have them try swapping the
mass air flow sensor.  After Howard Cooper replaced the
throttle body (among other things) on my S4 it stopped
throwing codes, but it still wasn't running quite right.  Then
they tried the MAF and since then it's better than it's ever
been, including the cold start hesitation that I used to have.
