The parts aren't really that expensive, it's the labor these places charge an hour. Call around and see who can do it the cheapest, unless you want to do it your self.

I had the exact problem with my wifes 99 Cabrio - parked for 9 months. Ended up having to have the shop reprogram the ECU - it then worked fine.

SOURCE: my 1998 vw is getting less mileage per gallon, and

yes it will!! you have issues with the tps and air flow valve on the throttle body also you may have to use a code tool to reset all that once the unit is replaced to insure proper throttle response and speed controll through the ECM to the new unit

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)

Could a bad throttle body cause a low hum while driving and a turbo underboost error code?


Has to be at a shop that works on turbos

None of the code checking etc, without vehicle
system knowledge, is of any value to you

Throttle Body is not humming

If you can buy factory manuals for lots of money,
maybe you can work on it, when you have trouble charts to follow

Throttle Plate Angle or % is subject to constant change, so unless
your friend knows the vehicle systems, then you wouldn't be here

Code p1580


Your code relates to throttle motor bank 1 circuit mallfunction, this can be caused either by a wiring fault, the throttle motor itself, or ECM the most common fault is the air flow meter also called air mass meter

Engine stalls under acceleration, shows code P1580, changed throttle body with new one but problem persists


I would worry or be concerned about the code.
The code is about the throttle sensor or actuator. If the sensor is faulty or the computer is not getting a good signal from the sensor it does not know what the throttle position is.
You might try resetting the throttle position - clear the code, key on but don't start, hold pedal to the floor, key off.

ETC light is on, engine has problems starting.


The EPC (Electronic Pedal Control) is the "fly by wire" system that controls the throttle, it took the place of the cable that went from the gas pedal to the throttle body on VW. If this light is on and there is also a P0102, MAF (Mass Air Flow) related code stored in the vehicle's computer, the EPC may be caused indirectly from a faulty MAF. If the EPC is on and there is no other codes stored, it could be a faulty electronic throttle body or need to be re-programmed. The vehicle's computer must recognoze the throttle body so when replacing it with new or used it will need to be programmed at the dealer. Recently I replaced a MAF (a common problem on VW's) on a VW Golf and when I cleared the code the EPC went off as well.

Check the engine codes, and replace or repair the faulty sensor (most likely the MAF sensor).
