I find that momentarily lifting with my right foot as I brake with my left
foot works extremely effectively. Anybody who has attended on of Audi's
winter driving courses on the ice in Finland can confirm this, no problems.

This feature is not unique to Audi, contrary to reports from other listers
who revive that hoary old story about 'Unintended Acceleration' it is not
unique to Audi, it pertains to all cars running the most recent versions of
the Bosch Motronic Engine Management Systems.

Do not disable this feature, it is the future of all modern motor cars,
learn the new technique. If you watch experienced Audi Quattro winter
drivers, you will find that they are able to keep their cars under complete
control at all times, it is very simple to adapt to.

Subject: [BiturboS4] left-foot braking & fuel (???) cutoff


First of all - I'm not member of this mailgroup - so please include me
to CC:
line while replying... THANK YOU!

I tried to search through many mailinglist about left-foot braking
issue but
there was no success to my specific problem... and my problem is that
when I
apply breaks with left foot while NOT releasing gas pedal there seems
to appear
something like fuel cut-off by ECU... I installed on my S4'00 similar
known from earlier quattros (had it on my B4'94, S4'94 and now have it
also on
my CQ'87) to switch off ABS and ESP but switching off these features
disable this fuel-cutoff feature/bug ...

Does anybody have solution to this problem? I understand that audi
have built this "feature" to save the transmission from excessive force
sometimes I still want to use my left foot on ice track or on snow or
in similar
condition ...

One thing which I was thinking is maybe to put some additional switch
ABS-aus) on wire from break pedal to ECU (at least I think I found
one!) but I'm
not sure does it help and I'm bit afraid also about possibility to
damage ECU...

thanks in advance!

best regards,
