You will need to read the 95040 immo chip eeprom in the ECU, then view the hex dump in a hex editor. Then the IC is adapted to the ECU and immo. With the SKC, you can adapt the ECU to the instrument cluster, and correct the immo ID with the VIN of your A4, so that the immo ID is adapted to your VIN. The ECU immo chip, has the ECU SKC stored on the eeprom. If you clear all those DTC, do any of them reoccur? The No Comms is not associated with the immo, it is likely due to the IC and ECU not adapted to each other. Or these problems are not related and I have to solve this in other way? Other question is can these immo problems cause "communication errors" on other components?Ġ1317 - Control Module in Instrument Cluster (J285)Ġ1330 - Central Control Module for Central Convenience (J393)Ġ0466 - Control Module for Steering Column Electronics (J527)Ġ0457 - Control Module for Network (J519)Ġ1320 - Control Module for Climatronic (J255) If you learn 2 keys, first will show 0-2, after learn 1 key, it show 1-2, after learn 2 keys, it show 2-2.Thanks for the replies! I'm not good at this VCDS stuff, but as I remember VCDS can read EEPROM, or I'm wrong? Maybe it would be enough to fix only ECU in this way, so after that instrument cluster could be adapted in normal way, because ECU would have car's immo info already? When you get that message, the cluster will show “x-y”, “x” is the learned key number and “y” is the total learning number. If you press “OK” before that message will cause key learn failure. 5)Ĭonnect the VVDI2 VAG commander to the car,Īt the last, you will get a message insert every key to learn, don’t press “OK” until you get message “Learn key success” at the bottom. Step 4 – key learning through VVDI2 VAG (No. If the OEM keys support change ID, you can make an OEM key, the method is same as 4th immobilizer cluster OEM key, select one original key position and continue ( Most OEM keys is not support unlock, it can be prepared again with lock status, then learn it as normal). You can unlock the locked OEM key in “Transponder Programmer->Other Key Tool”. (if you don ’t have working key, the keyless function will not work ) Make key for A6/A7/A8/Touareg need a working key Make key for A4/Q5/A5 don ’t need a working key So you can make key for other cars before key learning. The key is not locked before you learn it. Put the programmable key into VVDI2 key programmerĪfter making key successfully.
For there are many OEM keys on the market, keyless key result may not accurate 3)Ĭheck key is locked or not, is keyless key or not. Step 2 – Verify key lock status with the “Check Key Status” button (No. As long as you have the BCM2 data, you don ’t need to read again, no matter key learn, no matter when Else may enter lost all key mode, of course, if reading success, it is also right BCM2 dataīCM2 data is always for the same car. Under OBD Read BCM2 for lost all key process, if cannot read BCM2 data after disconnect power or you get disconnect power for next time read, this type may not support OBD read without working key, you need read BCM2 data with 5th BDM Programmerīefore you read BCM2 via OBDII, you’d better switch OFF/ON ignition again, Keyless cars press START/STOP button again to switch ON. It need disconnect BCM2 power (2 interfaces) for a few seconds.
You need read BCM2 data with 5th BDM Programmer (No. – Error “read data length error” in OBD read method: 1), read BCM2 need enter service mode, the cluster may become dark under reading. So far, most cars support read BCM2 data via OBDII(Add key and lost all key all support).
Step 1: Choose a method to read BCM2 data So we need read BCM2 data from BCM2 module (J393) If you want prepare a new dealer key, you must know the total 16 bytes CS.
Car commander immo off how to#
It’s vvdi2 manual of how to use VVDI2 VAG to make a dealer key for vag vehicles with the 5th immobilizer system.
