View Full Version : Recoding APR ECM w/ Vag Com-- Manual to Tiptronic?

07-11-2007, 08:16 AM
Now, I may be totally wrong here, but I have been told that you can recode the ECM from Manual to Tiptronic. Anybody know how to do this? I have read about changing from 'new' to 'old' style tiptronic, but I'm still not finding much on switching modes completely. I just picked up a Vag Com, so I should be able to make it work... right? Please help!

old and new refers to the TCM, not the ECM...

being a 98.5, you should be able to recode it, but there are a few ecu boxes that arent recodeable...

i recoded it when i sold mine to another person. open up control module -> engine -> coding -> itll give you a little pop up window that shows what number should be what for auto/manual, fronttrak/quattro, etc etc

It's P/N 8D0 907 557 P, which is the same part number I had with the stock box. I know this is a common number, it's got to be recodable. Any ever done anything like this before?

Sweet. I'll try it. Thanks!

Ok, so I'm trying to recode my ECM w/ the Vag-Com, The current code is 06201. (06=usa, 2= quattro w/o traction control, 0= 5-speed manual, 1= class B vehicle type). I NEED it to be 06251, the 5 being automatic trans. I'm not having any luck, and I think I might need a valid login code. The manual says they are located in the factory repair manual for my car... wtf? Can anyone help me with these?

Nevermind... figured out that it has nothing to do with the login codes. It just won't let me re-code it. I was able to change the code on the stock ecm, just not the APR ecm. Anyone else have problems coding a chipped ecm?

Anyone have any other ideas about this? Has anyone recoded an APR chip successfully?

if its an ATW, some of the ECU's are stubborn about recoding, i have had mixed success with certain ECU codes. You should be able to do it through VAG-COM

It's an AEB. I used the Vag-Com over and over last night and as soon as I hit 'Do it!' it would go right back to what it was originally coded to. I did that multiple times with no success. I don't know if I'm missing something or what? I recoded my stock ECM just to see what happened, and it worked the first time. aargh... The two ECM's match numbers, but there are different component numbers. Am I screwed?

Any ideas? Is it possible I need to recode the softcode somewhere else? I'm guessing I'm just screwed.

If that's the case, I've got an APR ECU for sale: P/N 8D0 907 557 P, stock and chipped modes, nDBW came out of a 99.5 A4 1.8T 5-speed. Great shape.

did you ever get this to work? I've got the same problem with an ECU I bought....trying to go from Auto to Manual......

08-08-2007, 12:22 PM
looks like we have one member that needs a auto ECU and one that needs a manual ECU - .........might be easier to just switch ECU's -lol

LOL!!! That would be awesome! One problem......mine is a GIAC K04!

08-08-2007, 08:11 PM
If I had a K04 and if you had a K03 then I suppose a swap would work great!! I never got it to work. Since I bought it and now have a second ECU laying around, I'm debating just sending it in to get it recoded. It would defeat the purpose of buying it used at a better deal, but hell, atleast I still have a spare ECU!!

LOL!!! That would be awesome! One problem......mine is a GIAC K04!

Crap. That's what I was afraid of.....I think I might be in the same boat. I still don't get why it won't work.....

It could just have to do with the chip manufacturers coding and the way they lock out certain features to prevent people from looking at their software. I don't know.
