Hi,
Trying to save FA date from new cas module but get error:
"warning I-Levels are not valid in this cas, they will not be saved"
any ideas? have just read another on the bench and it saved no problem.

I-Level (production and current) are part of FA. They are needed to calculate ecu updates along with other FA items.
If there is an invalid I-Level in the CAS you will get this warning.

Invalid as in a new bmw supplied cas will have latest firmware with higher I-Level?
any way of forcing the save working on bench?

If the cas is a brand new from BMW it will have no FA nor I-Levels. (Blank CAS)

Really?
I always thought that a new cas ordered with chassis number came with all details for car and keys and just needed sync once fitted,
this is all I have ever done when replacing with a new cas,
when it was fitted to the car with original ecu it worked fine without any errors so would assume the fa is correct. (problem still existed with dme after "repair" from well known repair specialist who insisted it worked fine while on bench) dme has now been replaced and new cas matched was just really trying to match the used cas that came with dme, easy enough to do on car but its 20 miles away hence trying to backup fa from new cas to write back to old cas on bench.

just copy FA from FRM(LMA) to CAS and code it
if autohex doesnot allow it its 2 min job in ncsexpert
