Hello,
I recently repaired a customer's odometer from an Audi A6 C6, 2008.
Sent to me with broken LCD backlight.
I replaced the inverter because it was interrupted on the secondary winding.
Prophylactically, without checking, I also replaced the 74HC08A and MOSFET Si9945A gate, because they reportedly fall frequently.
Instead of the 74HC08A, I gave the version without "A" that is normal, not Automotive grade.
Unfortunately, then I did not have how to test the meter outside the car, so I sent it back.
The customer put it in the car and everything worked.
A few hours later he called me saying that the word "dEF" appeared on the meter and the lights were still flashing. It also says that VAG-COM reports ICM errors, but that may be because I was plugging the meter into the power supply on my desk, so maybe it's all sensor missing errors etc.
What could this dEF error mean?
Could this have something to do with my repair? (I exclude some careless soldering, these circuits are huge, soldering according to the art)
He sent me a picture of the CD, you can't see anything burned out.
For now, I've told him to erase all errors and try to fire up, then read again.
Thanks in advance for your help.
best regards

He was doing a run with some quinol and something hit.
