2003 Sharan 1.8T AWC is fitted with "06A 906 032 HA" ECU. From ETKA, I find ECU "06A 906 032 QJ" may be fitted on Sharan 1.8T AWC engine, too. Could I relash the ABT tuned file from "HA" to "QJ" ECU? Due to these two ECUs could be both fitted on Sharan 1.8T AWC.

I goolge the difference between "06A 906 032QJ" and "06A 906 032HA" in the below web site.

the actual coding of the module is 0004 ( by VAG COM)
I checked this module in ETKA and it says that this
ECM has two emissions programs inside PRG 0GG and PRG
7GG, the interesting part is that program 0GG if for
EU4 compliance emissions ( Europe) and 7GG is for
TIER1 compliance emissions (Mexico version of Sharan)
I think that any of these programs is selectable by
coding. before 2005 there was a special version of the
module for the European Sharan (06A 906 032 QB)(
emissions program 0GG) and mexican Sharan (06A 906 032
HA)(emissions program 7GG) but it appears that this 05
ECM the QJ version has both has both. In ELSA it
doesnt gyve any info for coding it just refers you to
the Guided fault finding function of VAS 5052 for
coding, so I would like to know if it has some coding
options available and what other

Is it possible to change the difference emissions programs automatically in the flash, 29F800BB? How it works?
