I could certainly believe that maybe VW prevents this kind of matching on purpose to prevent someone from screwing up and installing the wrong kind of cluster or ECU in a car. (and yes, I realize this is an Audi manual and that it's concerned with matching a new cluster to an existing ECU and not the other way around like you're trying to do), however maybe clusters of certain types don't want to swap VIN info with ECUs of certain types. 'Engine control unit does not supply data on account of previous use with a control unit (dash panel insert) of a different category (tuning protection)' 'Channel 50 Adaptation 32000 System not OK'Īnd it mentions that it's caused by this: I searched around for that 'System not OK' error and found this:Īt some point it mentions that you could receive the following error: I wonder if the ECU doesn't want to talk to the cluster because they're from different engine types. Also the new VIN information does not transfer to the new ECU. (Login procedure does not produce an error nor a disconnect from VCDS.) With the original 2003 1.8T cluster and 2003 ALH ECU and following Ross Tech's Instructions I get a 'System NOT OK' error when entering the old SKC into adaptation channel 50 when I'm supposed to get VIN and IMMO-ID information. As we don't have the cluster from the 2003 ALH the donor ECU came out of I retrieved the SKC from the 24C04 EPROM in the ECU and confirmed I can log into the ECU. I retrieved the SKC out of the original 1.8T cluster, which I presume matches the SKC in the ECU that was working with the car. The Auto to Manual conversions have been done to the harness as per the PDF that floats around here on the forums. The ALH itself is from an '00, but we've got a '03 Auto TDI ECU and harness. We've got a 2003 1.8T Jetta GLX Wagon that's getting an ALH with a DRW 6-speed. I debated between TDI conversions and MKIV forum, but landed here since the swap is into a vehicle that is available as a TDI, it's just this one isn't.
