P1568 code
no symotoms.? how many miles on car 50k or 250k miles>?
no other DTC, did you use scan tool? and one that read ALL VW DTC. if not FAIL. you will.
how can I fix.?
you want to fix the car or the TB?
most cars, its a new TB.
im not VW savvy, (can fix any car) but not their policies.
anyone can go to vw.com and to the parts page and see what is sold
anyone. just do it.
my guess, is you didnt read the FSM yet, on this failure
why not? it explains how to isolate the true cause.
4th generation and 5 sub types. from FUN to blue motion.....
2002 to 2009
P1568
got others?>
* VW DTC 17579 (P1171) - Throttle Actuation Potentiometer Signal 2 Range/Performance
* VW DTC 17950 (P1542) - Throttle Actuation Potentiometer Range/Performance
* VW DTC 17953 (P1545) - Throttle Position. Contr Malfunction
* VW DTC 17976 (P1568) - Idle Speed Control; Throttle Position - Mechanical Malfunction
so what does it mean.
it means idle can not be controls for any of many reasons.
the tech makes sure the engine runs ok, is in closed loop hot.
if not we fix that first , because misfiring or bogging engines the idle can be impossible to control.
then check that the throttle butterfly plat is not sticking (clean it)
if the throttle motor sticks the motor is bad. end of live for TB.
my guess is you dont have a scan tool, am I right>?
fixing cars with out one, is a bad idea.
engines can go lean and stall or surge.
engines can go rich misfire and stall.
we make sure that is not happening first and
the law is, IDLE is the last thing to work right on all EFI engines.
hell carbs. (ever get a vacuum leak with a carb ,it stalls)
