Read True Mileage: How to Check Car Odometer

Hello everyone

I recently purchased the professional diagnostic system KKL+CAN (see also here; http://shop.dieselschrauber.de/product_info.php/products_id/46).). Well, anyway, I'm mainly interested in the function that allows you to read the mileage from the control units, because I strongly suspect that the odometer reading has been tampered with.
Da wird ja nun angepriesen dass bei EDC15 und EDC16 Steuergeräten den wahren Kilometerstand auslesen kann. My question about this:

What percentage of VAG vehicles from 2000 to 2010 had this type of control unit installed?

"It didn't work on a Seat Toledo 1M, model year 2003 (engine code BCB), a Skoda Fabia 5J, model year 2009, or a Fabia 6Y. Perhaps you could give me some tips on how to solve this problem using VCDS. This function is really important for my purposes."

Here's a kind of experience thread:
Okay, I'm ready. Please provide the German text you want me to translate.

Hi!
Thank you for your quick response. Do you think that in the future, more ECUs will be supported? Also, does the diagnostic tool display what type of ECU it is when reading data? I only briefly saw "Marelli" on mine.

Best regards,

Also, and... does the diagnostic tool actually show what type of control unit it is when you read it?

Yes, using the VAG part number or the ECU information within VCDS.
