I've heard that the replacment ECUs do not necessarily have the VW PN on them. The easy way to tell is to open the unit up, and look for the ROM chip on the daughterboard. count the pins. Then you will know for sure. I believe the magic number is 24.

I am trying to determine if my ECU is the 022D required for the chip upgrade.  I just pulled it out and looked at it and the only lable is a b&w Bosch label that shows the date of manufacture in 1996 and shows the VW part number as
BOSCH 0 261 200 284 /285

There is no "Digifant" number listed on the label.  Any ideas?

Thanks in advance!
