This from the Bentley manual for 1993-95 90

If you do a search for "function 07" in the Bentley manual you will find how to RE-code your ECU to many diffirent parameters ex: no EGR, euro code... etc.

Unfortunately for the MMS 200 there is no software coding, you have to ground couple pins on the ECU it self. (which is what I have)

For MMS 300 and 311 you can use function 7 of vag software to code the ECU that you want.

Code Control Module (VAG 1551 function 07)

The VAG 1551 Scan Tool must display a four-digit code during Control Module identification.

The factory performs ECM coding in the wiring harness at connectors B and C of the ECM.

The first three digits are coded via terminals 14, 16 and 19 of connector B and the fourth digit via terminal 9 of connector C.

If one of these terminals is connected to Ground a zero is displayed; if this terminal is not occupied (open), a 1 is displayed in the appropriate position of the code.

Example

Coding 1 1 1 1
Connector B B B C
Terminal 14 16 19 9


- If VAG 1551 Scan Tool does not display appropriate coding for vehicle ( page 01-59 ), check ECM terminal assignment using wiring diagram.

- If incorrect terminal assignment is determined, correctly install terminals in connectors B or C using wiring diagram.

- If terminal assignments are correct, replace ECM.

Digging up a really old post here!

Who can tell me what ECE version is? coding 1110

i have a audi 80 quattro 2.8 aah and i want to turn off everything, as per

1110
ECE version
Heated Oxygen Sensors (HO2S), EVAP canister purge regulator valve, EGR

i have performed similar coding using a mms300, however need to now use a mms200 for ship purposes

any ideas? is 1110 the correct coding im after?

thanks for any help

definitely raising a zombie here.
anyone got a login code into mms200 8a0-906-266a?
