Keep reading :-)

Meet the erwin - Electronic Repair and Workshop Information service. This is not only for professionals but erWin is also available to private individuals who want to repair their Skoda vehicle themselves! Thank you VAG!

erWin contains

1. all repair guidelines for Škoda Auto
2. further repair information available in PDF format (not available in all languages). 
3. additional information such as self-study programmes and training programmes. 
4. vehicle-specific information, such as maintenance tables, vehicle data and field actions is available in many languages. 
5. continuous update of data 
6. the Offboard Diagnostic Information System Service - Diagnostic Software 
1. with the advantage of carrying out an offboard diagnosis for all vehicles of the Skoda brand, which have a EU 5 type approval, through a SAEJ2534-compliant interface (diagnosis interface),
2. and the possibility of direct access to the selected repair and maintenance information during a current diagnostic session via the diagnosis software. 

Open Internet Explorer. That's important, other browsers doesn't works as expected.
Goto their home page https://erwin.skoda-auto.cz/erwin/showHome.do

First of all, choose surface and article language. I recommend you to set it to English or German (if you know it) as it should be most comprehensive info.

Now, go register https://erwin.skoda-auto.cz/erwin/showCustomerRegistration.do
And login after that.

Now to start working, you need to pay for service with Visa or MasterCard. You can choose the duration according to your needs:
One hour including printing rights €5.00 
One day incl. printing rights €25.00
One week incl. printing rights €88.00
30 days incl. printing rights €310.00
365 days incl. printing rights €2,850.00

One hour was enough for me to get all material for Fabia Mk2 and my friend's Octavia Mk2, but you need  fast navigation skills, lot of interaction with keyboard and mouse to save everything on your PC.

Before you pay, take a look around in menus and check their tour in "About erWin".

After payment that you will get instant access to all material, you can also check your car by VIN number.

Actually erWin is a good replacement for ETKA that requires a lot of dancing around computer to make it work. And it always updated. Anyway, 5 euro is a not so much money for that information.
