Title: Trying to make a spare ECU for an Audi TT 2.0 TFSI med9.1. The original ECU is an 8J0907115N Post by: cawadany on August 02, 2016, 01:58:20 AM Hi to all. I am trying to make a spare ECU for an Audi TT 2.0 TFSI med9.1. The original ECU is an 8J0907115N.
The car's owner doesn't want to open original ECU, so I found a bdm backup with same HW: 0261S02519 and SW: 1037387549, and I found an used ecu from VW Golf 5 2.0 TFSI med9.1. (1K0907115). With E2PA I did immo off in eprom of this bdm backup, changed the coding for dsg (backup is from manual car, this one has dsg) and wrote flash and eprom on ecu with bdm. The car starts but it doesn't accelerate and the idle is unstable. DTC stored is 17796/P1388/005000 - Control Module Malfunction - DBW Throttle Monitoring. Is it possible that I have found an used faulty ecu? Or the problem can be immo off related? Title: Re: Trying to make a spare ECU for an Audi TT 2.0 TFSI med9.1.

Sorry, but my problem is related to the same topic , also because I used the same software for immo off on med9.1. Title: Re: Trying to make a spare ECU for an Audi TT 2.0 TFSI med9.1.

Doing the same thing and I have the same issue. I have ordered a replacement ecu. If problem persists will let you know it wasn't the ecu.

The original ECU is an 8J0907115N Post by: k0mpresd on August 03, 2016, 09:09:42 AM i sent an ecu to a customer for an a3. customer complained of same issue, throttle issues.
swapped ecu, still problem persisted. ended up refunding customer since i was unsure of issue and i was not in person to diagnose properly. i have never had a problem with med9 and throttle before but you seem to have similar problems as well.

The ecus was immo-off? Or cloned? If immo-off, with only eprom or with eprom+flash? Title: Re: Trying to make a spare ECU for an Audi TT 2.0 TFSI med9.1.

Now I don't have the car to test, but I will try with immo-off with e2p and flash. Title: Re: Trying to make a spare ECU for an Audi TT 2.0 TFSI med9.1.

I BDM cloned my old ECU to a this new ECU and the ECU works fine without throttle body errors. Mismatched eeproms maybe?
Title: Re: Post by: cawadany on August 03, 2016, 10:38:56 AM I think immo-off only e2p solution it's not good for all med9.1 sw
Title: Re: Post by: k0mpresd on August 03, 2016, 01:00:03 PM I think immo-off only e2p solution it's not good for all med9.1 sw this seems to be the common factor between them all. if it was mismatched e2p, ecu would not boot.

It's an immo-off related problem. I tried with old solution (eep+flash) and the car works perfectly!
