this is what i got from LOC ...... looking at your VIN number, u can determine whether ur altezza is having LSD or not.....
Look for the codes
ao1a-no diff
ao1b-have a diff
ao2a-no diff
ao2b-have a diff
so if this code ends in B it means u have a diff
hope this helps....... mine doesnt have a diff......so kenot driff.......hehehe
