Hi all,

I have an Audi TT 8n that is giving me a lot of headaches. The current ECU has a chip tuning, the fuel consumption is very high. I get a maximum of 350km with a full tank.
Currently I have a big problem that the TT starts normally, but then after 10-20 seconds the 3 cylinder fails. The whole thing lasts until the car reaches 60/70 degrees and the error disappears. Now I bought a new control unit "8N0906018Q", the old one has the same housing, but VCDS shows me the following part number "8LO 906 018 J".
Now I would like to have the original software on it, as I don't know if the seller had changed anything on the control unit.
Can anyone give me the correct .bin file for this ECU?
And if possible, to remove the SAI as the pump is defective....

Maybe you guys can help me out on this one...

Thanks in advance.

018Q will be an AJQ ECU
018J will be an APP ECU

Should be interchangable without issues, only AJQ has no SAI from factory.

Just flash the new ECU with a stock 8N0906018Q job done.

where do you have the information that the 018Q is for an AJQ? I had already the new ECU in my car and my SAI started. Every information I found about that ECU is saying that it is for the APP.
That's why I bought it.
Any original stock file available here? Still new into this forum so need to figure it out first, what's in here..

Maybe my info is wrong, but have had APP and AJQ cars before. Should be able to flash AJQ file and be done with it. Or code out appropriately.
