Ecm Fried

Hello everyone, i have a question about a 2009 volkswagen tiguan 2.0t car crank no start, diagnosed it and found fried ECM (engine control module). I am wondering if someone can give me info if it is possible to program a used ecm and i do have ross tech vag-com but i think a login code for the car will be required to be able program a used ecm, can anyone tell me how i can get that login code?

Hi ,

You need to send the used ecu to someone that can clear the immobiliser information and then you can program the ecu to the car . 

You can then extract the pin code from the dash panel and then program the ecu .

Sali the only way that I know that you can program the ECM on a VW or Audi is by using ODIS the factory scan tool. They have everything locked down. You will need an LSID that you can apply for from NASTF​.​org followed by a special approval by VW thst is done via Germany. Hope this Information helps

Hi Sali,

My understanding is that officially, used is a no go for 2005 and up VAG vehicles. I have had customers try the dealer route. It did not end well. Once the component protection is written, I am told that even ODIS will not marry a used PCM. There is a PIN stored, MAC address, VIN and Component Protection. It is not only stored in the Flash section of the ECU but in the EEPROM which is only accessed in Boot Mode. (Open up ECU and add ground or power to points on the board) I could be wrong on the ODIS ability but I don't know anyone that has succeeded with ODIS. The Abrites tool can turn the Immobilizer off on some earlier ECUs without programming but the VIN will not match and the Immobilizer lamp will stay on. (vehicle registration problems when VIN is read)

Because the VAG group, Mercedes and BMW all fit into this catagory, I decided to invest into specialty equipment to clone PCMs. The BMW tool called Autohex II uses a different method than cloning. It reads the ISN (similar to component protection) from the donor and writes it to the DME. It is only used for BMW. I use the Kess and Ktag from Alientech, the Galetto from FG Technology, The Abrites and BitBox to copy and process the PCMs. Some of the ECUs require the use of multiple tools. Be aware that there are fake tools on ebay and all over the internet, BTDT.

The 2009 Tiguan should have a Bosch MED17.5 ECU. It has a Protection Password that has to be deciphered over the internet. Without the discovery of the password all you can do is read ECU data, no flash, no EEPROM. Once the software has located the password, you can open up the ECU and activate Boot Mode by grounding specific pins. Then the Galetto tool can read the Flash and EEPROM. You then repeat the process with the donor and write the EEPROM and Flash to the donor. Once completed, the case needs to be resealed to keep moisture out. If all goes well it is plug and play. The vehicle does not know the difference as the Flash and EEPROM are identical to the donor. You have to make sure the numbers match on the ECU. For instance: 06J 906 026 H is a common Tiguan number.

Below is a picture of my setup. Being interrogated is a Bosch ME … Passat with 2.5L engine)

For more information you can contact me on Linked In or IATN.
