Title: audi q7 edc16 chksum issue
Post by: airtite on January 26, 2022, 11:49:23 PM
I recently purchased a non runner q7, it had the steering lock actuator issue. I have fixed that a a few other things. Now the car starts but dies 5 seconds later logging the following.

P1610 - 006 - Memory Check Sum Error - Intermittent

I took a read using my mpps 13 cable and then wrote another file from my other q7 same ecu hardware/software number, mpps does the chksum while its writing and the issue still persists?

attached file is the read I took from the file. Any pointers?

it looks like a physical issue with the ECU, I have another ECU here I just need to do an immo off to test

The file is fine if you read it from the car after reflash.
Also this is only a calibration data. You have to check the whole file.
