ASJ engine only has 2 lambda probes and no SAI
ASJ = EU2 compliant
AZR engine has 4 lamda probes and SAI system
AZR = EU3 compliant
SAI = Secondary Air Injection system
I think the engine code is part of the V5 IIRC.

Engine code will also be in the service book (inside cover), and the other data sticker in the boot.
Will also be on the timing betl cover (LHS) IIRC

Unfortunately that's wrong
Both engines have SAI and 4 lambda probes, the difference is that an ASJ ECU doesn't care about SAI or the post-cat lambdas, whereas the AZR one does, because of the EU3 emission norm.

That's concerning as the lambda\SAI information was lifted from Elsawin v3.6

AFAIK, ASJ=AZR-SAI

SAI is present on all these engines, I can't find the link to the self-study program for the B5 RS4 just now but I'm sure it's stated pretty clearly in there too

Euro 2 and euro 3 emission (asj-azr) emission specs are mentioned in the RS4 training guide. Technically there are no differences
