almost all cars with computers have what called adaptive stratagy. the PCM (powertrain control module) learns what the engine is doing and make little compensations over time. example: it the engine runs lean, the 02 sensors will let the pcm know and it will richen the mixture until its normal again. your code means that something is affecting the idle quality and the pcm is adjusting the idle and now there is no more adjustment left. possibilies are, running lean due to injectors clogged or vacuum leak, unmetered air leak around MAF sensor ( reads the air coming in) fouled plugs, timing, plugged fuel filter... could also be rich due to plugged air filter, leaky injectors, bad fuel pressure regulator.... you'll need someone with a some knowlegde and tools to help you with this one if your a novice. This type of code is almost impossibe to guess due to the amount of possibilities. "Throwing darts "as we call it in the industry gets expensive!

[8|] I have seen several posts on this subject (P1582), but no one ever replies to ever fixing their cars. Some of these posts are quite old. I am sure some of the cars must have been repaired by now! I also have the code P1582 in my 97 Jetta and was hoping some one could steer me in the right direction.....thanx [:)]

Just take off the air intake pipe from the throttle body and open the butterfly valve and clean the inside of your throttle body. The error code you get is typically from a build up of carbon that is preventing the valve from either openeing or closing all the way.

I WONT TAKE CREDIT FOR THIS BUT HERE IS THE SOLUTION>>>>

you need to have the throtle body remaped
did you unhook the battery latley

Maybe a good ecu reset would be in order after a through cleaning? Thats my first two steps...

Jrailer -> RE: Code P1582 (8/1/2008 6:33:09 PM)

cleaning it out wont do a thing on this problem
the throtle body needs to be recalibrated (remaped)with a vw scan tool not your cheap $50  code readers
i do this all the time and have many posts on it
you see it mostly on battery installs or un hooks

Not from what ive been told with people having this exact issue, they did what I mentioned and fixed said code so dont think you know more than everyone else there buddy ol pal. Whatever you can try the cheap almost free method or you can buy a 300 dollar vag com, your choice...
