Hello,

can dealer actually see that coding was done if I revert changes before doing car maintenance?

Are there any logs with timestamps or something like that?

Let's say I change some value from "0" to "1". Before visiting the dealer I change it back to "0". Is there a way to track that there was a modification done?

It's your car, if you code it's none of the dealer's business. Besides that they really don't care.

They will only care if you screw up the coding...ie expert mode... and F Up an ECU, and then try and get the dealer to fix it for free.

Otherwise.... nope.

Little note, It's nearly impossible to brick a module with coding, so even if you mess something up FDL coding (excluding flashing) you can always revert back to stock coding easily. That being said, FDL coding is harmless and cannot void any type of warranty that I can see. Vehicle order coding on the other hand can void warranty, their systems will see you've tampered with the vehicle order either adding a new one or removing it which I can 100% see cause issues. Also if you were to flash/update software on any module that can cause warranty issues. Standard FDL coding is fine.

As for dealers detecting coding, I'm sure if they dig they can see it was tampered with but it doesn't leave a flash count like updating software would leave. I'm not familiar with all their tech but in theory it could leave a trace even if you put it back to stock FDL coding. I wouldn't worry though, you'd have to go to a dick of a dealer for them to deny warranty because you have coding on the car.

All memory keeps a record of how many times it's been written to.

If your flash count was whatever, 267 the last time your BMW was connected to ISTA and info sent to BMW and it's 356 the next time, they know it's been changed and it wasn't them.

Do they care?

In most instances, no.

If you have major issue costing $10,000 of warranty claim, you better believe they will care.

I don't believe standard FDL coding changes any flash counters, correct me if I'm wrong though.

Every write to memory increases a counter by 1
