Here is the Audi A6 2005-2011 ELV module MCU pinout with XPROG-M ECU programmer V5.5.5 from obdii365.com:
OEM= 4F0905852B
MCU= 3L40K
Read as secured
I have done 4pc of this unit last month.
Short cables max 12cm long.
When it don’t read always try to lift reset pin
(I have never done it but some Xprog is sensitive and then try lift reset)
Operate by following my instruction, one friend used the adapter (BDM) and wires with a length of 10 cm. RESET leg lift.
MCU is dead! Work 100%
