Last week my friend has told with me about this product.But I know what it is.So I seach it in the website in the uobd2.com.
who knows Lexia-3?
What can it do with Citroën?

Lexia3 is Dealer software for the PSA group (Citroen and Peugeot) it can read fault codes , recode keys ,show live data , nearly all that a dealer can do , price wise i`ve seen them sell from China (since it is a cracked software) from as little as £70 posted.
