Diagbox 7.83 review:

Review 1:

Took hours and hours to install the software, but afterwards it all works well. Read a few forums regarding the correct version of the software to install, you only need to go up to a certain point – after that the software gets more difficult to get to work properly. I use it on a 2012 DS3 to recalibrate the steering sensor and it works a treat.


Review 2:

This is an older version and you have to realise that Diagbox is the actual software you need to install not lexia. But i got it to work on my grand picasso 2009 1.6hdi after alot of you tube videos. Just do not update it beyond v5.1.


Review 3:

Arrived on time, Already had software installed so only really purchased for the lead which worked fine after simple install of drivers. my only disappointment was that it has no decals/stickers to distinguish the product but does not effect the use
