6N2 idle slow on startup.

Our Polo,[AHW engine] has had this problem for some time after it came in suddenly. First start of the day it idles around 500revs. After a short time it comes up to roughly 900rpm. When starting while warm it revs at 900rpm. Normal driving everything works as it should.Replacing the temp sensor & cleaning the throttle body made no difference. I also replaced the Lambda probe as the car has done 150,000km.
I bought a new cable from Ross Tech[HEX-USB+CAN] because my older one, VAG COM 409-1 from memory, wouldn't recognize the ECU.
VCDS shows, 00282 Throttle Position Actuator [V60]
26.00 Output Open
From what I have read this means that the throttle body is terminal & needs replacing.
What do you guys think?

Someone else reporting the same/similar thing here: Mk4 1.4 16v throttle body alignment problem

And here: Fault Code 00282 Throttle Postion Actuator - Volkswagen Lupo - Club Lupo

As you mentioned, a new throttle body sounds like the solution (providing a clean and adaptation didn't do anything).

Thanks Lucas. I remember reading the club polo link, not sure about the VW Audi forum one. The poster had slightly different symptoms to ours. Once slightly warm, first 100meters or so, it performs faultlessly. It is a bit of a worry that after replacing his with a new one, he finished up with the same fault codes as mine. As most will know, the throttle body is very expensive so it's not an option of just trying a new one.
I haven't tried the adaption process yet as I am a little concerned it could make it worse.

Hey mate, if you travel south, I can check it up for you.

Just try the adaption, it shouldn't make it worse, but its a risk you will have to take, or leave the car as is if you dont want to spend money.

I have done a few adaptions with the vagcom cable on the throttle bodies of 6n1's, it will complain if it doesn't work but i don't think it can break it and make it worse

Thanks, I will give it a try when the weather cools down a bit.

I need to sell the Polo as I have bought a Tiguan but I would still like to fix it before I do.

Thanks for the offer Miro. I have a friend who is a electronics guru who was to come tomorrow morning but in view of our hot conditions I have put it off until the weather cools & we can think straight. He will look at the electrical diagram & check the cable going to the ECU.

Thanks for to all the replies so far. If you think of anything else, repost. I will come back if & when I have success.
