>The Passat has less than 20K Km on it, so it
should not be a worn starter or corroded wires,
but anything is possible.
Battery would be the only thing to suffer with age. I imagine it's charged.
>To take out the battery and clean the poles on
this car is tricky, it needs back-up power. It
would forget the throttle positions. The throttle
adaptation algorithm can only be initiated by a
VAG-COM type computer.
Throttle angle settings don't always change with battery unhooked. I had to
do throttle adaptation only once on my '99 bug, when putting in a new
battery for the first time and never on my '00 bug, even after a new battery
went in. Granted, these are less complex cars than a Passat but usually,
when power is restored and the ECU and Immobilizer recognize each other, all
is well. Just need to recode the radio.
Funny thing - the Heidelberg radio I got in my '92 Eurovan didn't need
recoding after installing a new battery. Doesn't work well - a ton of
static over the stations sounds - but that seems to be another issue, which
I would appreciate help with.
