Exacty what was needed 5/5

ECU Testing refurbished my Merc gearbox ecu quickly and with superb customer service. I recommend them highly. As an ordinary consumer, I would just note that it is important to have a good mobil mechanic to assist in this kind of repair.

Satisfait du travail et rapidité de retour! 5/5

Je suis extrêment content du travail réalisé par ECUTESTING sur mon calculateur de BVA! On peut suivre en direct l'avancement des réparations... Je n'ai fait que 1000kms depuis que j'ai ré-installé mon calculateur, aucun défaut ne s'est ré-affiché. Merci ECUTESTING
