Just did a TBA with the VAG tool and experienced something that seemed strange to me.

The adaptation process started after switching to basic settings and displayed ADP-OK (or whatever the little right text field displays) but the % values continued to switch between 84 and 85% it never locked on to one value, and I just exited the module.

I turned key-off, removed vag cable, turned key on, waited about 30 secs and then started the car. The engline made a weird noise, like it wasn't too happy, and started right up with an idle around 1300 RPMS.

I turned the car off, repeated the above process, everything happened the same way again and the idle was high again with the weird noise at start-up. This time I left it running and the idle dropped slowy to normal over the next few minutes.

I decided to come post before I drove it just to make sure nothing is out of sorts.

Also, the first time I did a TBA, I had no problems it started and idled just fine right off the bat. Anyone have any ideas why this time everything seems so screwy?

TIA =)

Was the car cold? Coolant must be below 100C.

Then popped the other ECU right back in an re-adapted. That's when this funny business started.

In fact, perhaps it was too cold (not driven today), and that's the problem.

It's normal.

Coolant must be between 5 and 100C.

should I use the old key in ignition when cold routine.

SO the loud sound/jumpy rough start at startup from the car being in "choke mode" and nothing to worry about?

I'm excessively paranoid about these things. =)

Thanks for the help Taner.
