Title: Audi c5 allroad 2.7t ARE SAI and LAMBDA 2 Delete. Post by: nicraM35 on January 17, 2025, 12:50:55 PM Hi, I recently did a little cleaning up under the hood. I deleted the SAI and installed downpipes without the second lambda sensors. Now the car throws a check engine light because of it. Could someone tell me what cable I need to delete it from the ECU? I only have access to VCDS but am willing to buy anything necessary. Thanks in advance!

you have to generate xdf file to your ecu #-box 1 you need a hex editor to do hex compare best software is called Scooter Beyond Compare 2 you need m-box bin file and the xdf 3 tuner Pro software is needed to generate and edit your maps NOW open the editor go to > session > new session > hex compare load m-box to the right your ecu-x to the lift go to tuner pro -open xdf and m-box bin let's say you need boost map in the tuner pro copy the address hex from boost map now go to hex editor >search >goto > put the hex address the hex editor will bring both maps against each other you copy the address that appears under your ecu file name put it in the address in the boost map that's how i figured mine Title: Re: Audi c5 allroad 2.7t ARE SAI and LAMBDA 2 Delete.
