Since I live in iran there are few vw/audi cars in my country so I haven't used them yet..

I think you are right... how can I make sure if I choose the right area? How do you
choose option1 and option2 for toyota?

I ordered from www.autelonline.com, I contact with sales@autelonline.com and after I
pay the money they will send the cable out, I think i'll have it in one week or two,
depends on traffic jam :D

Nissan, hyundai, and honda have worked decent for me.

  VAG (VW/Skoda/Audi/Seat) would be better with more direct functions (software fulfilling actions in background like reset of service does right now, adressing the channel actions without you fussing about on it). Coud do with a menu for functions like much used items like adaptions etc. like this to make it better/faster to work with; without going through all kinds of channels.

Need of more directions when you are in channels, the label files for a lot of channels are incomplete and a lot of the times you don't know what data you are looking at (have to disconnect / trick sensors to see what what is). The help files could be greatly updated as well on this one.

Programming is great, like VCDS but should also be more easy to read data , pins etc. from the car ECU's so it's more easy to use (no need to fill in yourself, should be readable from the eeproms).

Could not give it a percentage but it's not close to a 100% yet

Peugeot ... lot of cars don't do auto detection and it is hard to find your way in the woods of ECU's , models, build codes, motorcodes, etc. etc. There is a lot of data and functions available using maxisys, but it's quite a journey to get into the right selections before you can access it. There should be better detection or better guidance in your selections.

Not all functions seem to be there. Varies a lot per model, some cars have awesome support, others I believe should have more actuators, adaptions etc. available. Don't have other Peugeot tools so I can't verify with those, but some fellow carshops use Bosch KTS and Delphi; detection is better on those (for a lot of other car brands as well to be honest)
