Title: B7 Audi MED9.1 EEPROM read Post by: MoparFreak69 on April 13, 2015, 09:12:58 AM So I have not had any luck extracting the EEPROM information from my ECU. I understand that the B7 cars can be a royal pain to pull it. A clone BDM 100 isn't working for me and a real one is not in the budget. I would really like to be able to extract the EEPROM and BIN from this car so I can play around with working on a stage 1 tune.
Some people have mentioned around the forums about using an MPPS cable, but I cannot find a definitive answer as to whether the clones actually work in the B7 or not. I have heard mention of a BDM 192(?) that supposedly works better with the ECU. Any experienced persons willing to give me insite? My end goal is to be able to read/flash over OBD like I can with my ME7.5 GTI, but if I have to remove the ECU each time it isn't that big of a deal. I am not asking to be spoon fed here, I am just looking for information that I can read to determine what will actually work in my car, without bricking another ECU. Any links/posts/blogs/threads that can direct me to where I am trying to be? I am fairly confident in ME7.5, but I cannot crack this stupid MED9.1 to save my life! My secondary goal is to have the information needed in one place so anyone searching like I did can find the answers they need in one place. Thanks in advance!

You should be able to do it via BDM 100. On mine I had to supply 12v through the ecu plug because the internal relay on the BDM 100 wasn't working. You need to make a bench harness and supply all the needed power pins.

I have not had a issue reading B7 ECU's. I cannot however write just the flash back. I must either write a single file. (Flash+E2P) or flash it with MPPS. But reading has never been a problem. BTW, I can just flash the E2P by itself. |
